About this item
- [Professional Drill Bit Set] This Professional Drill Bit Set features high-speed steel construction with a gold oxide finish, resulting in increased hardness and corrosion resistance. These attributes make the drill bits suitable for use on hardened working materials, further enhancing their versatility and durability.
- [3-Flat Shank] The distinct design of the 3-flat shank ensures a secure fit for bits, preventing any slipping and saving time and frustration. Shank sizes vary: 1/16"-11/64" is round, 3/16"-3/8" is three-flatted, and 25/64"-1/2" comes in both 3/8" reduced shank and three-flatted options.
