Milwaukee router bit set with 12 mm shank, 7-piece

Cobalt alloyed micro-grain tungsten carbide for the best durability and service life; thicker carbide allows repeated sharpening.
To create a strong connection, the carbide is brazed to the body with a three-layer process (silver-copper-silver).
Multi-axis CNC sharpening process gives the cutting edge an ultra-sharp geometry and allows it to stay sharp longer.
Anti-friction coating reduces snagging, friction and heat during cutting, and also protects the router from corrosion and resin build-up.
Anti-kickback shoulder limits the cutting depth and reduces kickback.
