All cold saw blades used to cut steel products should have a coating. The most common coating is a 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.
