AT REDUCED SHANK DRILLS
AT Reduced Shank Drills—also known as Silver & Deming drill bits—are heavy-duty drilling tools designed to produce large-diameter holes while fitting standard drill chucks. Featuring a reduced shank, these drill bits allow larger cutting diameters to be used with common 1/2-inch drill chucks, eliminating the need for specialized tooling in many applications.
