The black oxide coating adds real performance value to HSS cold saw blades by improving lubricity, reducing friction, and enhancing heat resistance during cutting.
Key advantages include:
-
Improved chip flow – Black oxide helps reduce chip welding and galling, especially in mild steel, by allowing chips to evacuate more cleanly.
-
Lower friction = longer life – The coating reduces surface friction between the blade and material, which decreases heat buildup and extends blade life.
-
Corrosion resistance – Offers added protection against rust during storage or downtime.
-
Better surface finish – Leads to cleaner cuts with less burring when paired with proper RPM and tooth count.
This coating is especially useful in dry or semi-dry cutting environments where coolant is limited or inconsistent.
