Cold Saw Blade & Tooth Recommendation
Need help finding a cold saw blade? Not sure the # of teeth for the job? We can help!
Which cold saw blade and tooth configuration do I need?
Start with your saw. The blade has to match its required diameter, thickness or kerf, arbor bore, drive-pin pattern, cutting capacity, and permitted RPM. Then pick the tooth configuration based on the metal, stock shape, section size, wall thickness, and cutting orientation. Thin-wall tubing and small profiles need a finer pitch and more teeth. Thick-wall tubing and solid stock need a coarser pitch and fewer teeth so chips can clear. In the HSS blade tables this calculator uses, BW is the usual starting tooth form for light-gauge tubes and sections, and C (also called HZ) is used for solids and thick-wall tubing. No single tooth count works for everything. Enter your blade and stock measurements below for a starting recommendation, then confirm the full blade specification and cutting conditions before you order.
Important: A matching diameter does not by itself mean the blade fits your saw. The calculator gives a starting point. It is not a machine rating, and it does not guarantee results for every alloy, saw, or cutting process.
For the best starting recommendation, have these details ready: saw make/model or blade specifications; metal and grade; solid, tube, pipe, or profile; outside dimensions; wall thickness; and cutting orientation.

How to choose the correct configuration
1. Confirm the blade fits the machine. Match the saw manufacturer's specified blade diameter, body thickness or kerf, center bore, drive-pin holes, cutting capacity, and allowable blade speed. If the diameter matches but the bore, pin pattern, thickness, or operating speed is wrong, the blade is not compatible.
2. Identify the complete workpiece. Record the metal and grade, hardness if you know it, whether the stock is solid or hollow, outside dimensions, wall thickness, cutting orientation, and whether you cut pieces one at a time or in a bundle. Two tubes with the same outside diameter can need different pitches if their walls differ.
3. Match pitch to the section. Thin-wall tubes and small sections need a finer pitch and more teeth so individual teeth don't hit a thin edge on their own. Thick walls and solids need a coarser pitch and fewer teeth so the gullets have room for larger chips.
4. Match the tooth form. In the HSS tables used here, BW is the normal starting form for light-gauge tubes and profiles. C/HZ is a roughing-and-finishing geometry for solids and thick-wall tubes, normally used at pitches above 4 mm. Some thin-wall and production jobs call for a specialized B or chip-breaker grind. Confirm that it suits the saw, the material, and the motor capacity before using it.
5. Confirm the cutting process. Conventional low-RPM cold saws that run coolant commonly use resharpenable HSS blades. Higher-speed dry-cut, TCT, and cermet processes need blades and settings made for those machines. Don't carry settings over from one process to another.
6. Set and verify the cut. Tooth count is only one part of the setup. Use the machine or blade supplier's speed and feed for your material, supply the specified coolant or lubrication, and clamp the work securely. During the cut, watch chip formation, sound, finish, and machine load.
| Application | Starting direction | Typical HSS form in this calculator | Why |
|---|---|---|---|
| Thin-wall round or square tube | Finer pitch; more teeth | BW | Keeps teeth engaged and reduces shock on a thin wall. |
| Small profile or light-gauge section | Finer pitch; more teeth | BW | Gives steadier engagement across an interrupted section. |
| Thick-wall tube or pipe | Coarser than thin-wall tube | C/HZ | Larger gullets and a stronger roughing/finishing geometry. |
| Solid round, square, or rectangular stock | Coarser pitch; fewer teeth as section size increases | C/HZ | Leaves room for larger chips and cuts heat from packed gullets. |
| Stainless or tough alloy | Application review required | Usually material-specific HSS/coating/form | The material may need a different pitch, speed, feed, coolant, or coating. |
| Aluminum, brass, or copper | Use a compatible non-ferrous blade and saw setup | Application-specific | Non-ferrous metals use different tooth geometry and often very different operating speeds. |
| Bundled or stacked material | Separate review | Application-specific | Tooth engagement and chip evacuation differ from a single piece, so a single-piece result may not apply. |
Worked examples
These examples use the site's tables and show how the answer changes with the stock, even at the same blade diameter.
Example: thin-wall round tube
For a 350 mm blade cutting 2-inch round tube with a 0.060 to 0.090 inch wall, the site's table gives a starting recommendation of 280 teeth, BW form. That number comes from a table lookup. Before ordering, you still need to confirm bore, kerf, pinholes, alloy, machine RPM, feed, and coolant.
Example: solid round stock
For a 350 mm blade cutting 1 3/4 to 2 1/4 inch solid round stock, the site's table gives a starting recommendation of 140 teeth, C form. With fewer teeth than the thin-wall tube blade, it has a coarser pitch and more chip space. The exact material and machine conditions still decide the final specification.
Example: orientation changes the answer
Scotchman's blade guide shows that a 2-inch square tube may need a different pitch when cut across the flat than when cut diagonally. In its example, the pitch goes from 6.5 mm on the diagonal to about 7.5 to 8.5 mm across the flat. That's why the calculator asks for cutting orientation and doesn't rely on outside size alone.
Confirmation checklist
Confirm these details before you order from a Cold Saw Blade Store Blade and Tooth Count Recommendation:
- Saw manufacturer and model
- Blade diameter
- Blade body thickness or listed kerf
- Arbor or center-bore diameter
- Drive-pin hole number, diameter, and bolt-circle location
- Machine RPM and blade/process type
- Metal type, grade, and hardness if known
- Solid, tube, pipe, angle, channel, or other profile
- Outside dimensions and wall thickness
- Cutting orientation
- Single piece or bundle
- Coolant or dry-cut requirement
- Finish, burr, production-rate, and blade-life priorities
Missing a size or cutting an unusual alloy or profile? Don't just pick the nearest table value. Send us the saw model, blade dimensions, metal grade, stock dimensions, wall thickness, and a photo or drawing of the cross-section, and we'll review the application.
How many teeth should my cold saw blade have?
It depends on blade diameter, stock shape and size, wall thickness, material, and cutting orientation. At the same blade diameter, more teeth give a finer pitch for thin sections. Fewer teeth give a coarser pitch with more chip space for thick sections and solids.
What do BW and C/HZ mean?
BW is an alternately beveled HSS tooth form for light-gauge tubes and profiles, usually at tooth pitches of 4 mm or less. C/HZ alternates a higher beveled roughing tooth with a square finishing tooth. It is used for solids and thick-wall tubes at pitches above 4 mm.
Should thin metal use more or fewer teeth?
More. Thin-wall material needs more teeth and a finer pitch so several teeth share the cut and no single tooth is overloaded. Thick-wall material and solids need fewer teeth and a coarser pitch so chips can clear without packing the gullets.
Is blade diameter enough to select a cold saw blade?
No. Along with diameter, confirm thickness or kerf, arbor bore, drive-pin pattern, cutting capacity, and operating speed. Then choose tooth count and geometry for the material and workpiece.
Can one blade cut tubing and solid bar?
It can cut both, but one tooth configuration is unlikely to work well for both thin tubing and large solid stock. Thin walls cut best with a fine pitch and steady engagement. Solids need a coarser pitch and more chip capacity. If the two jobs differ much, keep separate application records and use separate blades.
Does the metal change the recommendation?
Yes. Metal grade and hardness can change the best pitch, tooth geometry, coating, cutting speed, feed, and coolant. The calculator's baseline tooth count comes from stock geometry tables, so check the result against your metal before you treat it as an order specification.
Can I use an HSS blade on a dry-cut saw?
Not without checking first. A low-RPM HSS cold-saw blade and a high-speed dry-cut blade may not be interchangeable. Use only the blade type, size, and RPM range that the saw and blade manufacturers specify.
