Evolution 11/16 in. Diameter x 2 in. Depth Annular HSS Cutter with 3/4 in. Weldon Shank CC687L

Included pilot pin: Evolution recommends that all annular cutters be cooled properly throughout the cut to ensure cutter life is optimized. In order to accomplish this, an included pilot pin is required so the coolant can be delivered directly to the cutting surface. The included pilot pin is yet another value-added feature that makes Evolution annular cutters the easy choice for industrial drilling applications. Evolution Standard Geometry: Evolution standard geometry is sufficient for most drilling applications. Manufactured specifically to maximize hole accuracy while minimizing cutter vibration and extending annular cutter life.
