HSSÂ M35 Co5 VAPOR STEAM TREATED BLACK OXIDE
This blade is made from M35 tool steel containing 5% cobalt in addition to the alloy elements already present in the M2 blades. They are considered super high-speed steel blades which will provide extra hardness (66 HRc) for cutting stainless steel and hard alloy steels above 800 N/mm².
Do you think you're going through too many blades or they're dulling too quickly? Try our M35 Co5 blades - most customers experience two times the number of cuts compared to standard M2 blades.
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.
All blades are ground in the US on advanced computer numerically controlled (CNC) grinding equipment by industry experts with over 40 years of industry experience.Â

Running flood coolant?
Add CSS 2000 Semi-Synthetic Sawing Fluid
Keep tooth temperature down and chips moving. The right coolant is one of the easiest ways to get more cuts out of every HSS blade.
