What This Product Line Covers
Use this guide as a quick selection reference before sending your material, machine photo, blade marking, and trial quantity. Final blade design can be adjusted by cutting material, machine model, bore, pin-hole layout, and sample feedback.
Regular Steel Cutting
For steel bar, pipe, square tube, and mixed profiles from small P50 machines to larger P170-P200 cutting machines.
Fast Cutting Series
Designed for higher equipment utilization. Suitable when machine rigidity, clamping, coolant, and feed control are stable.
Thin Kerf Series
Lower kerf and thinner body reduce material loss, especially when cutting high-volume steel bar or tube with repeated lengths.
Thin-Wall Steel Pipe
Higher tooth counts for thinner wall pipe and cleaner cutting with controlled burr and deformation.
Hard Steel / Stainless
Dedicated grades and coating options for bearing steel, 65Mn, 42CrMoA, stainless steel, and other demanding materials.
Bore and Pin Holes
Bore, pin-hole quantity, pin-hole diameter, and PCD can be customized from your current blade photo or machine drawing.
Technical Features
For metal cutting, the final performance depends on the complete system: tip material, blade body, tension treatment, grinding accuracy, and machine matching.
Cermet or Carbide Tips
Imported cermet or carbide grades can be selected according to mild steel, stainless steel, pipe, hard steel, cutting finish, and machine stability.
Stable Steel Body
High-grade blade body, laser cutting, and stress control help reduce vibration and improve cutting stability under load.
Application Tooth Geometry
Different tooth forms are used for solid bar, thick-wall tube, thin-wall pipe, hinge parts, steel plate, and stainless steel.
Coating and Lubrication Options
Coated stainless series and suitable micro-lubrication can improve service life when the machine and application justify the upgrade.

Cutting Parameter Reference
These formulas help buyers discuss cutting speed and feed per tooth with the factory. They are references, not a substitute for sample testing on the real machine.
Feed Per Tooth
Fz = F / (N x Z)
Fz: feed per tooth, mm/tooth
F: feed speed, mm/min
N: spindle speed, rpm
Z: number of teeth
Reference: bar material Fz = 0.04-0.07 mm/tooth; pipe material Fz = 0.03-0.05 mm/tooth.
Blade Linear Speed
V = π x D x N / 1000
V: cutting speed, m/min
D: outside diameter, mm
N: spindle speed, rpm
Reference: medium/low carbon steel V = 100-130 m/min; high carbon and alloy steel V = 70-100 m/min.
Cold Saw Blade Selection Notes
A cold saw blade should not be selected by diameter alone. The same 285mm blade can perform very differently on solid bar, tube, profile, stainless steel, or aluminum. Use the notes below as a practical first check before confirming carbide grade, cermet grade, tooth count and tooth geometry.
For solid workpieces, several teeth should stay engaged during cutting. If too few teeth are engaged, the blade can grab or chip. If too many teeth are engaged, chips cannot clear well and cutting heat increases.
Mild steel, stainless steel, copper, brass and aluminum need different speed ranges. Stainless and hard alloy materials normally need more careful RPM and feed control than mild steel.
Bright, uniform and curled chips usually mean the feed is closer to correct. Dust-like chips may indicate feed is too light. Blue, burnt or welded chips may indicate excessive heat, feed, speed, or poor coolant delivery.
A stable spindle, clean flange, firm vice and correct pin-hole fit are part of blade performance. Even a good blade can fail early if the workpiece moves or the blade has excessive runout.
| Cutting Condition | What to Confirm First | Blade Selection Direction | Common Risk if Ignored |
|---|---|---|---|
| Mild steel solid bar | Bar diameter, machine RPM, coolant condition, bore and pin holes | Start with a stable carbide or suitable cermet option; tooth count should allow chip space for solid material. | Short blade life, chipped teeth, heavy burr or slow cutting. |
| Steel tube or profile | Wall thickness, shape, clamping method and bundle cutting requirement | Use tooth geometry that controls vibration and protects the tooth tip when entering thin walls. | Tooth grabbing, vibration marks, burr and broken tips. |
| Stainless steel | Stainless grade, wall thickness or bar size, coolant, machine rigidity | Use application-specific carbide or cermet grade with controlled speed and feed. | Heat build-up, material pick-up, poor finish and early dulling. |
| Aluminum or non-ferrous metal | Profile thickness, extrusion shape, surface finish requirement and chip evacuation | Do not use a steel-cutting setup blindly. Non-ferrous cutting usually needs different tooth geometry and higher chip clearance. | Material sticking, rough surface, noise and unstable cutting. |
Practical sample approach: if the buyer is unsure about RPM, feed or grade, we recommend starting with a conservative sample blade based on the current blade marking and material photo. After the first cutting test, we can adjust tooth count, tooth form, carbide/cermet grade, coating or body thickness.
Is cermet always better than carbide?
No. Cermet can perform very well on suitable machines and materials, but carbide can be safer when the machine condition, clamping or cutting data is not fully confirmed.
Why do we ask for material photos?
The blade for solid bar is not always the same as the blade for tube, profile or plate. Photos help confirm the workpiece shape before we recommend tooth geometry.
Can one blade cut mild steel and stainless steel?
Sometimes it can, but it is not the best way to control cost per cut. Stainless steel usually needs more careful speed, feed and grade selection.
What should be checked before mounting a blade?
Clean the blade, flange and mounting surface. Confirm bore fit, pin-hole position, rotation direction, coolant delivery and workpiece clamping.
What to Send Before Quotation
For cold saw blades, a professional quote depends on matching the blade to the real machine and material. If you are not sure, photos and videos are enough for a first check.
Current Blade Marking
Send OD x kerf x plate/body x bore x teeth, or send a clear photo of the blade marking.
Machine and Bore
Send machine photo, bore size, pin-hole quantity, pin-hole diameter, and PCD if available.
Material and Size
Confirm mild steel, stainless, hard steel, pipe, tube, solid bar, plate, hinge part, plus diameter or wall thickness.
Need a Sample Recommendation?
Send your blade size, material photo, machine photo, and trial quantity. We will recommend a practical carbide or cermet grade first, then adjust after your cutting test result.
