Evolution 13/16 in. Diameter x 2 in. Depth Annular HSS Cutter with 3/4 in. Weldon Shank CC812L

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. Evolution iD Style Geometry: When drilling through multiple layers of material, Evolution’s ID style cutters are recommended. Using this custom geometry enhances accuracy and saves time when compared to the alternative method of stopping after each layer and removing the residual slug. This allows for a single ejection of slugs when drilling through stacked material.
