Metal cutting tools are the cutters, drills, taps, dies, reamers, and saw blades that remove material to shape a metal part. Choose by the operation first (drilling, milling, turning, threading, sawing), then by work material, tool material and coating, and geometry such as flute count. Victor Machinery's online store organizes its catalog around exactly these categories, so the operation is the most reliable starting point for a search.

Start With the Operation, Not the Tool Name

Each cutting action has a characteristic tool and a characteristic failure mode. Matching the tool to the operation prevents most wrong purchases.

Victor Machinery's category menu follows this structure: End Mills, Milling Cutters, Drill Bits, Reamers, Taps, Dies, Threading Tools, Hacksaw and Bandsaw Blades, and Lathe Tool Holders are listed as separate departments. If you know the operation, you can go straight to the matching department instead of browsing the alphabetical index.

The Main Categories in a Machine Shop

Drill bits

The entry point for holemaking. The catalog separates drill bits from cutting tools, bits, and blades as a group, and also lists combination drill and taps for drilling and threading in one step.

End mills and milling cutters

End mills are listed by geometry: 2-flute and 4-flute, single-end and double-end, long length, ball nose, and metric sizes, in HSS. Flute count is the visible selection axis here — 2-flute for more chip clearance, 4-flute for a stronger edge and better finish on harder materials.

Reamers

Used after drilling when a hole needs a controlled diameter and smoother wall. They are a distinct category rather than a variant of drill bits, which reflects their finishing role.

Taps and dies

Taps cut internal threads; dies cut external threads. The catalog breaks taps down by thread standard and style — hand taps in NC and NF, spiral point taps, spiral flute and STI taps, pipe taps, metric taps, left-hand taps, Acme taps, and long or oversize taps. Dies follow the same logic: HS round dies in NC and NF, carbon steel hex dies, metric dies, left-hand dies, and pipe dies. Die head chasers are listed separately for production threading heads.

Saw blades and lathe tooling

Bandsaw blades and hacksaw blades form their own department. Lathe tool holders and lathe and drill chucks sit under machine accessories rather than cutting tools, which is a useful distinction: the holder is not the cutter.

Selection Factors That Actually Change the Cut

• Work material. The catalog separates HSS (high-speed steel) tooling from carbide tooling (solid and tipped) and carbide inserts plus indexable tools. HSS is the general-purpose default shown across end mills, taps, and dies; carbide is offered as its own line for higher production or harder work.
• Flute count and geometry. End mills are sold as 2-flute, 4-flute, ball, long, single-end, and double-end. Each variant exists because chip evacuation, rigidity, and reach trade off against each other.
• Thread standard and hand. Taps and dies are organized by NC/NF, metric, pipe (NPT/NPS), left-hand, and special pitch. Buying the wrong standard or hand is the most common threading mistake, so this is the first filter to apply.
• Size range. Special pitch taps and dies are split into up to 1/2 inch, 9/16 to 1-1/8 inch, and 1-3/16 inch and larger. Die head chasers are split by head size (5/16 and 9/16, 3/4 and 1 inch, 1-1/4). Size determines which listing applies to you.
• Tool holding. Tap wrenches and guides, die stocks and holders, and tapping and die heads are separate from the cutters themselves. A correct cutter in the wrong holder will not cut correctly.

Matching a Tool to the Job: A Worked Example

Suppose you need a threaded hole in a piece of mild steel.

1. Drill the hole. Select a drill bit sized for the thread's minor diameter. The catalog lists drill bits as their own department, and combination drill and taps exist if you want one tool for both steps.
2. Choose the thread standard. Decide NC, NF, metric, or pipe. This narrows you to one tap family.
3. Choose the tap style. A hand tap for manual work; a spiral point tap for through holes on a machine; a spiral flute tap for blind holes where chips must come out the top.
4. Match the tap to the hole type. Through hole versus blind hole is the deciding factor between spiral point and spiral flute.
5. Hold it correctly. Use a tap wrench and guide from the threading tools group so the tap starts square.

The same logic applies to milling: pick the end mill flute count and length from the operation (roughing versus finishing, deep versus shallow), then confirm the holder.

Wear Signs and When to Replace or Resharpen

A dull cutting tool shows up as changed results before it shows up as visible damage:

• Increased cutting force or spindle load for the same cut
• Poor surface finish where the tool previously produced a good one
• Oversize or out-of-round holes from a drill or reamer
• Torn or galled threads from a worn tap or die
• Chipping or rounding on the cutting edge under magnification

When these appear, stop and inspect the edge. Whether a specific tool can be resharpened depends on its geometry and material — end mills and drills commonly are, while many taps and dies are replaced rather than reground. The catalog does not state sharpening services, so treat resharpening as a shop decision based on the tool type.

Practical Takeaways

• Identify the operation first; the Victor Machinery catalog is organized that way.
• Use the standard and size filters for taps, dies, and chasers before anything else.
• Match flute count and tool material to the work material and the hole or cut type.
• Remember that holders, wrenches, and guides are separate purchases from the cutters.
• Replace or resharpen when results degrade, not only when the edge is visibly broken.

For a small machine shop, the practical way to build a supply list is to organize it by the job it does: cutting tools (end mills, drill bits, taps, reamers), measuring instruments (micrometers, calipers, indicators), workholding (clamps, vises, chucks), and consumables (abrasives, saw blades, cutting fluids, fasteners). Stock the sizes and types you use weekly; buy specials only against a specific job. The sections below cover what each category does, how to choose within it, and where the common buying mistakes are.

Cutting tools: end mills, drill bits, taps, reamers

These are the tools that remove metal, and they are also where most wrong purchases happen, because the same nominal size comes in many material, flute, and geometry combinations.

End mills

• Material: High-speed steel (HSS) is tougher and more forgiving on manual machines and light setups; solid carbide holds an edge longer and runs faster but chips under vibration. For a small shop with older or lighter machines, HSS is often the safer first purchase.
• Flute count: Fewer flutes (2) give more chip clearance for slotting and softer materials; more flutes (4) give a stronger core and better finish for profiling and harder materials.
• Configuration: Single-end vs. double-end, square vs. ball, standard vs. long reach. Buy the reach you actually need — long end mills deflect more.
• Metric vs. inch: Confirm which system your drawings use before ordering.

Drill bits

Match the bit to the material and the hole requirement. Jobber-length bits cover most general work; stub or screw-machine lengths are stiffer for shallow, accurate holes. For holes that must be sized precisely, drill undersize and finish with a reamer.

Taps and dies

This is the category where specifications get confused most often. Before ordering, confirm all four of these:

A tap and die set is a reasonable starting point for occasional threading, but production or repeat work is better served by individual taps in the styles that match your hole type. Keep tap wrenches, guides, and screw extractors on hand — broken taps are a normal shop event, not an exception.

Reamers

Use reamers when a drilled hole needs a controlled diameter and finish. Order them to the finished size you need, and leave enough material in the drilled hole for the reamer to cut rather than rub.

Measuring instruments: calipers, micrometers, indicators

Choose by what the tool measures and how tight the tolerance is, not by brand tier alone.

• Calipers — general outside, inside, depth, and step dimensions. The everyday first measuring tool.
• Micrometers — precise outside diameters. Use when caliper resolution is not enough for the tolerance on the drawing.
• Indicators and other measuring tools — dial test indicators for runout and alignment; squares and setup tools for checking work before cutting.

Two buying rules that prevent most returns: match the range to the largest part you measure, and match the resolution to the tightest tolerance you inspect. A tool that is more precise than your process needs costs more and does not improve the part.

Workholding: clamps, vises, chucks

Workholding determines whether the cut is stable, so it belongs in the same purchase plan as the cutters.

• Clamps and vises — for milling and drilling setups on the table.
• Lathe and drill chucks — match the mount and capacity to your machine spindle.
• Tool holding — holders and adapters sized to your tool shanks.

Buy workholding that fits your machine's table slots and spindle taper. A vise or chuck that does not mount correctly is unusable regardless of quality.

Consumables: abrasives, saw blades, fluids, fasteners

These are the items that stop work when they run out, so stock them by consumption rate rather than by project.

• Abrasives and deburring tools — used constantly; keep common grits and shapes on hand.
• Bandsaw and hacksaw blades — stock the blade sizes your saw takes, since a broken blade halts cutting.
• Cutting fluids and fluids — replenish before they run low.
• Fasteners — keep the common sizes used in fixtures and setups.

The rule for this category: never let a high-frequency item hit zero. Special sizes can wait until a job calls for them.

How to decide what to buy first

1. List the operations you perform most often (milling, drilling, threading, turning, sawing).
2. For each operation, list the sizes and standards that appear on your actual drawings.
3. Buy the common sizes in each category in HSS or carbide according to your machine's rigidity.
4. Add the measuring tool that covers your tightest routine tolerance.
5. Stock consumables at a level that covers your normal reorder lead time.
6. Buy specials — odd pitches, long reach, unusual thread standards — only against a confirmed job.

Common buying mistakes to avoid

• Ordering a tap or die without confirming the thread standard. NC, NF, metric, and pipe threads are not interchangeable.
• Buying carbide for a machine that cannot support it. The tool will chip before it wears out.
• Choosing a measuring tool by brand instead of by range and resolution. The wrong range is useless even if the quality is high.
• Skipping workholding. A good cutter in a loose setup produces a bad part.
• Letting consumables run out mid-job. Stock by usage rate, not by project.

Victor Machinery's online store organizes its catalog by these same functional groups — abrasives, end mills, drill bits, taps, dies, reamers, measuring tools, workholding, and saw blades — so you can work category by category when building a stock list.

Buy metalworking equipment by working backward from the operations you actually perform: cutting (end mills, drill bits, taps, dies, reamers), measuring (micrometers, calipers, indicators), workholding (clamps, vises, chucks), and sawing consumables (hacksaw and bandsaw blades). For each category, match tool material and geometry to your workpiece and spindle, match measuring range and resolution to the tolerance you must hold, and verify the interface (shank, tap size, chuck type) fits the machine you already own. Victor Machinery's online store is organized around exactly these categories, with an alphabetical index and a "My Tool Crib" list for repeat ordering, which suits small shops buying in ones and twos rather than case quantities.

Start with the operations, not the catalog

A small shop or serious hobby setup rarely needs everything at once. List the jobs you take in, then buy the tooling each job forces you to own.

Victor Machinery's category menu covers abrasives, end mills, air tools and grinders, fasteners, burrs and deburring tools, files, mill and lathe accessories, carbide inserts and indexable tools, gages and setup tools, milling cutters, reamers, clamps and vises, hand tools, saw blades, counterbores and countersinks, indicators and measuring tools, taps, cutting tools and bits and blades, lathe and drill chucks, threading tools, dies, lathe tool holders, tool holding, and drill bits. Use that list as a checklist against your job list — anything with no matching job can wait.

Cutting tools: match material and geometry to the workpiece

Tool material

High-speed steel (HSS) is the default for hand-fed and lower-speed work, and it is what most of Victor Machinery's end mill, tap, and die listings are built around — HSS end mills in 2-flute and 4-flute, single and double end, plus long and metric sizes; HSS hand taps, spiral point taps, and round dies. Carbide (solid and tipped) and indexable tooling appear as separate categories, and are the choice when you run higher speeds or need longer edge life in harder material. If your spindle is a manual mill or lathe without high-speed capability, HSS is the practical starting point; add carbide only where a specific job justifies it.

Geometry and flute count

• 2-flute end mills clear chips well and suit slotting and softer materials.
• 4-flute end mills give a stronger core and better finish for profiling and finishing.
• Ball end mills for contoured surfaces; metric sizes when the drawing is metric.
• Spiral point taps push chips ahead of the cut — good for through holes. Spiral flute taps lift chips out — better for blind holes. Victor Machinery lists both, plus left-hand and metric variants.

Threading: the size trap

Taps and dies are the easiest place to buy the wrong thing. The store separates hand taps (NC and NF), spiral point taps, special pitch taps by size band (up to 1/2 inch, 9/16 to 1-1/8 inch, 1-3/16 inch and larger), pipe taps, metric taps, left-hand taps in inch sizes, left-hand taps in metric and pipe sizes, Acme taps, long and oversize taps, combination drill and taps, and spiral flute and STI taps. Dies split the same way: HSS round dies (NC and NF), carbon steel hex dies, special pitch dies by size band, metric HSS round dies, metric carbon steel hex dies, left-hand dies, and pipe dies. Decide thread standard, pitch, direction, and hole type before you order.

Measuring tools: buy to the tolerance, not to the catalog

Pick resolution and range from the tightest tolerance you must hold, then avoid duplicates.

• Micrometers and calipers cover most outside and general dimensions. One micrometer in your common size range plus one caliper covers a large share of small-shop work.
• Indicators and other measuring tools for runout, alignment, and setup.
• Gages, squares, and setup tools for checking angles, squareness, and machine setup rather than part dimensions.

Two rules that prevent wasted money: don't buy two instruments that cover the same range and resolution, and don't buy a coarser instrument than the tolerance requires. If a print calls out a tolerance tighter than your current instrument can resolve, that instrument is the purchase — not another general-purpose tool.

Verify the interface before you order

Tooling that doesn't mount is money spent twice. Check these before checkout:

1. End mill and cutter shanks — diameter and type must match your collet or holder.
2. Tap and die sizes — thread standard, pitch, and direction, as above.
3. Chucks — lathe and drill chucks must fit your spindle or arbor.
4. Tool holding — the holder category exists precisely because shank-to-spindle mismatch is common; confirm the holder you have accepts the tool you're buying.
5. Die heads and chasers — die head chasers are listed by head size (specials for 5/16 and 9/16, 3/4 and 1 inch, and 1-1/4 die heads), so chasers are only useful with the matching head.

Buying and reordering for a small shop

Victor Machinery's storefront is built for piece-by-piece purchasing rather than bulk: browse by category menu or the Alphabetical Index, keep a "My Tool Crib" list, and use Express Ordering for repeat items. The site also lists Export Sales and an ordering info page, which matters if you buy from outside the US. Pricing is not shown in the material available here, so confirm current price and availability on the product page or by contacting the store before committing to a purchase plan.

A practical sequence for a first order: buy the cutting tools for your next three jobs, one measuring instrument at the resolution your tightest tolerance needs, the workholding to secure those parts, and saw blades to cut the stock. Add carbide, special taps, and extra measuring tools only when a specific job demands them.

Precision measuring instruments are the tools you use to verify that a machined feature actually matches its print tolerance. The right choice depends on four things: what feature you're measuring (outside diameter, inside diameter, depth, flatness), the tolerance you need to hold, where you're measuring (machine side or inspection bench), and how often you'll repeat the measurement. Victor Machinery's catalog groups these tools under Micrometers and Calipers, Indicators + Other Measuring Tools, and Gages, Squares, Set Up Tools, which maps closely to how most shops organize them.

The main categories and what each one is for

Victor Machinery lists Micrometers and Calipers as a top-level category and separates Indicators + Other Measuring Tools and Gages, Squares, Set Up Tools, so you can browse by function rather than by brand.

Match the instrument to the feature, not the other way around

Work backward from the feature on the drawing:

• Outside diameter or thickness → outside micrometer for tight work, calipers for quick checks.
• Inside diameter or bore → inside micrometer or bore gage; calipers only for rough sizing.
• Depth or step → depth micrometer or the depth rod on a caliper.
• Runout, concentricity, flatness → dial or test indicator with a suitable stand.
• Squareness and setup → squares, gage blocks, and setup tools.

If a single feature has both a loose and a tight dimension, don't force one tool to do both jobs. A caliper that reads a rough OD quickly is not the tool you want on a ±0.0005 in. bore.

Precision, resolution, and repeatability are not the same thing

These three terms get used interchangeably, and that causes most bad purchases:

• Resolution is the smallest increment the tool displays. A digital caliper may show 0.0005 in. while its actual accuracy is far looser.
• Accuracy is how close the reading is to the true value.
• Repeatability is how consistently it returns the same reading on the same part.

A tool with fine resolution but poor repeatability will make you chase tolerances that aren't real. For production checking, repeatability usually matters more than a flashy resolution number.

Shop floor vs. inspection bench

The same feature may need two different tools depending on where you measure:

• Machine side: speed and durability matter. Calipers, indicators on magnetic bases, and quick-check gages keep the spindle turning.
• Inspection bench: stability and reference standards matter. Micrometers, bore gages, gage blocks, and squares belong here, ideally at a controlled temperature.

Buying a bench-grade instrument for the machine side often means it gets dropped, contaminated, or knocked out of calibration. Buying a shop-grade tool for final inspection means you can't trust the numbers.

Common selection mistakes

• Chasing the highest precision number when the tolerance doesn't require it, then struggling with a tool that's slow or awkward to use.
• Using calipers for everything because they're convenient, including bores and tight ODs where they aren't accurate enough.
• Ignoring the size range. Micrometers and bore gages cover specific ranges; a 0–1 in. micrometer won't measure a 1.5 in. shaft.
• Skipping the reference. Inside micrometers and bore gages need a master or gage block to set them; without it, the reading is meaningless.
• Forgetting calibration. Any instrument used for acceptance needs a calibration path, whether that's gage blocks, a setting master, or an outside service.

A practical way to decide

1. List the features you measure and their tolerances.
2. Assign each feature to the category table above.
3. Pick the least expensive tool that reliably covers the tolerance and the size range.
4. Confirm you have the reference standard or master the tool needs.
5. Decide whether it lives at the machine or at the bench, and buy accordingly.

If you're equipping a shop from scratch, start with calipers for general work, one or two outside micrometers in your most common size ranges, a dial indicator with a stand, and a set of gage blocks or squares for setup and reference. Add inside micrometers, bore gages, and depth micrometers as your work demands tighter IDs and depths. Victor Machinery's category structure — Micrometers and Calipers, Indicators + Other Measuring Tools, and Gages, Squares, Set Up Tools — is a reasonable checklist to browse against as you build out that set.

For a beginner machinist, the practical starting point is a small core of cutting tools and measuring instruments that covers the most common jobs: drilling, threading, milling, and checking the result. Victor Machinery's catalog organizes machinist tools into categories such as drill bits, taps, dies, reamers, end mills, micrometers and calipers, indicators, and lathe and drill chucks. The right combination depends on the material you cut, the hole or thread size you need, and the machine you run — not on buying one of everything at once.

The two families of machinist tools

Every basic shop kit splits into tools that remove metal and tools that verify what you removed.

Cutting tools shape the part:

• Drill bits — start holes. Victor Machinery lists drill bits as their own category alongside cutting tools and blades.
• End mills — cut slots, faces, and profiles on a milling machine. The catalog separates them by flute count and configuration: 2 flute and 4 flute, single end and double end, long, ball, and metric HSS end mills.
• Taps — cut internal threads. The store indexes hand taps, spiral point taps, spiral flute and STI taps, pipe taps, metric taps, left hand taps, and special pitch taps by size range.
• Dies — cut external threads, in round and hex styles, inch and metric, plus pipe dies.
• Reamers — size a drilled hole to a precise diameter.
• Counterbores and countersinks — recess a hole for a bolt head or chamfer an edge.

Measuring instruments confirm the part is correct:

• Micrometers and calipers — outside dimensions, diameters, and thicknesses.
• Indicators and other measuring tools — runout, alignment, and setup checks.
• Gages, squares, and setup tools — reference dimensions and machine setup.

A shop with only cutting tools is guessing. A shop with only measuring tools is not making anything. Budget for both from the start.

Choosing cutting tools by job

Work backward from the feature you need to produce.

Two selection rules matter more than the rest:

1. Match the tool to the material. High-speed steel (HSS) tooling is the standard general-purpose choice in this catalog — HSS end mills, HSS taps, HSS round dies. Harder or more abrasive work pushes you toward carbide, which the store lists separately as solid and tipped carbide tools and carbide inserts.
2. Match the tool to the hole type. A through hole can use a spiral point tap that pushes chips ahead of the cut. A blind hole needs a tap that pulls chips back out, such as a spiral flute tap. Getting this wrong is one of the most common beginner failures — the tap bottoms out and breaks.

For thread work specifically, confirm three things before ordering: the thread standard, the nominal diameter, and the pitch. Victor Machinery indexes taps and dies by exactly these attributes, including special pitch sizes in ranges like up to 1/2 inch, 9/16 to 1-1/8 inch, and 1-3/16 inch and larger.

Choosing measuring tools by tolerance

The instrument must be finer than the tolerance you need to hold. A caliper reading to a coarse resolution cannot verify a tight bore.

• Calipers — fast, versatile, good for general dimensions and quick checks.
• Micrometers — better repeatability for a single dimension such as a shaft diameter or a thickness.
• Indicators — for movement, runout, and alignment rather than absolute size.
• Gages, squares, and setup tools — for checking angles, flatness, and machine setup.

Pick the range to cover your largest expected part, and pick the resolution to be a step finer than your tightest tolerance. If you routinely work at a given tolerance, the measuring tool should resolve meaningfully below it — otherwise you are reading noise.

Workholding and machine accessories

Cutting and measuring tools do nothing without holding the work and the tool. The catalog covers this under clamps and vises, lathe and drill chucks, lathe tool holders, and tool holding. For a beginner:

• A vise or clamps secure the workpiece on a mill or drill press.
• A chuck holds drills and work on a lathe or drill.
• Tool holders position cutting tools in the machine spindle.

These are not glamorous purchases, but a part that moves during a cut ruins the tool, the part, and sometimes the machine.

A sensible buying order for a new machinist

1. Start with the highest-frequency items: a set of drill bits, a caliper, and the taps and dies for the thread sizes you actually use.
2. Add measuring depth: a micrometer in your most common size range, then an indicator for setup work.
3. Add milling capability: end mills in the flute counts and lengths your jobs require.
4. Add precision hole finishing: reamers and counterbores once drilled holes need tighter control.
5. Expand by thread and size: special pitch, metric, pipe, and left-hand taps and dies as jobs demand them.

Buying in this order keeps money in tools you will reach for daily instead of a drawer of one-off sizes.

Where to look in the Victor Machinery catalog

The store's category menus and alphabetical index are the fastest route to a specific tool. Relevant entry points include:

• Cutting Tools + Bits + Blades — drill bits and general cutting tools
• End Mills — HSS end mills by flute count, length, and configuration
• Taps and Dies — threading tools by standard, size, and pitch
• Reamers, Counterbores and Countersinks — hole finishing
• Micrometers and Calipers, Indicators + Other Measuring Tools, Gages, Squares, Set Up Tools — measurement
• Clamps and Vises, Lathe and Drill Chucks, Lathe Tool Holders, Tool Holding — workholding and machine accessories

If you are unsure of a size or standard, the alphabetical index and the size-based subcategories (for example, special pitch taps split by diameter range) let you confirm the exact specification before ordering.
