Reduced Shank Drill Bits

Reduced Shank Drill Bits for Larger Holes with Standard Chucks

Reduced shank drill bits allow larger cutting diameters while fitting standard drill chucks, making them useful for drilling oversized holes without specialized equipment. The smaller shank works with common handheld drills and drill presses while still providing the capacity needed for metal, wood, and plastic. For similar large-diameter drilling, many shops also use silver & deming drill bits designed for wider hole sizes.

In machining and production work where shorter tools are preferred, technicians often rely on screw machine drill bits built with compact lengths for added stability. Some drilling setups also include slow helix drill bits designed to help manage chips in harder materials. Shop at JB Tools with fast shipping and free shipping on orders over $99!
