05A106 - Walter SST Core Cut Annular Cutter 1-3/8 Inch x 1 Inch Depth

The SST Core Cutters feature cutting-edge surface treatment technology that efficiently removes porosity for a flawlessly smooth finish. This enhanced design facilitates optimal material evacuation during drilling, resulting in improved product longevity and reduced drilling time. The state-of-the-art treatment also reduces friction with the work surface, minimizing heat generation. Additional features of these core cutters include fully ground extra large flutes, a modern tooth design and cutter geometry, a special bronze SST surface treatment, and a universal shank.
