WWM320 Bronze-Coated Insert for Stainless Steel and HRC35–HRC45 Hardened Materials
WWM320 is a milling insert made for stainless steel and hardened materials in the HRC35–HRC45 range. The bronze coating is there to cut friction at the edge.
Two things tend to go wrong when milling stainless steel: the workpiece sticks to the cutting edge, and the hardened skin layer wears the insert down fast. The WWM320 is set up to deal with both. Wear and chipping resistance stay strong, cutting runs stable, and the surface comes out clean.
Each part is engineered and QC'd against the exacting standards your equipment demands.
aimed at stainless steel, so chips clear instead of welding to the edge
keeps friction down, which slows wear and helps hold tolerance
