51/64" Reduced Shank HSS Drill Bit 1/2" Shank 3-Flat Shank

The 51/64" Reduced Shank HSS Drill Bit is designed for accurate drilling while remaining compatible with standard 1/2" drill chucks. Manufactured from high-speed steel (HSS), this drill bit provides durability, heat resistance, and reliable cutting performance for a wide range of drilling applications.

The reduced 1/2" shank allows larger drill sizes to be used with standard hand drills and drill presses without requiring larger chuck capacities. Its 3-flat shank design helps prevent slipping in the chuck, providing a secure grip and improved torque transfer during drilling.

Ideal for metalworking, fabrication, maintenance, and general shop use, this drill bit performs well when drilling into metal, plastic, and other materials requiring precise hole sizes.
