Revolutionarybriteview coating will protect and last for years. Woodtek ® straight shaper cutters have a rugged, bright yellow, PTFE (polytetrafluoroethylene ) briteview ™ coating which protects the cutter and increases the visibility for safer use.: Micro-grain carbide cutting surfaces have been diamond honed to 800 grit for tighter-fitting cuts time after time. CNC-machining to +/-0. 001" tolerances and dynamic balancing help ensure smoother cuts and vibration-free operation. Positive shear angle is ideal for working with hardwoods, softwood, composites and laminates. By reducing the "bite" taken out of a workpiece, the anti-kickback design greatly reduces the risk of dangerous kickback. 1/2" bushing included. Imported.
