What Are Cold Saw Blades?

Cold saw blades are most commonly made out of M2 steel for cutting ferrous and non-ferrous metals. Cold saw blades are typically ran on low RPM cold saw machines that run between 15 and 60 RPM. The term “cold saw blade” is used because the heat generated when cutting is transferred from the blade to the chips created by the saw blade. Companies will often consider a cold saw when minimal burr and more precise cuts are required. HSS M2 Cold Saw Blades are used to cut round and square tubes/pipes, solids, angle iron, structural shapes such as extrusions and even forgings.

M2 Cold Saw Blades are made from M2 DMo5 tool steel. During the manufacturing process they are heat treated and hardened to 64-65 HRc, triple tempered, and press quenched to preserve their flatness. Every cold saw blade undergoes a quality control check. During this process we test for runout on flatness, surface roughness, blade thickness, cracks, and scars. Flatness is checked at every point on the surface and roughness is checked via infrared deflection.

In addition to M2 HSS Cold Saw Blades, we offer HSS M35 Co5 Cold Saw Blades which are hardened a bit more to 66 HRc and contain 5% cobalt in addition to the alloy elements already present in the M2 cold saw blades. You can find out more about M35 cold saw blades by clicking here.

All cold saw blades used to cut steel products should have a coating. The most common coating is black oxide, sometimes referred to as vapor steam coated. The coating is most important to help prevent galling. Galling is caused by friction between sliding surfaces, most commonly found in metal on metal applications when there is inadequate lubrication between the surfaces. The combination of the coated blade and your flood coolant will prevent this issue.
