Built from high-speed steel with 5% cobalt for higher heat resistance, these twist drill bits are made to handle demanding drilling where standard HSS bits can struggle. The 135° split point helps with faster starts, and the 3-flat shank is designed to reduce slipping in the chuck.
- 12-piece set of 1/4-inch (0.25 in) jobber-length twist drill bits with a storage case
- M35 cobalt construction (high-speed steel + 5% cobalt) for improved heat resistance
- 135° split point for more controlled starting
- 3-flat shank designed to help the bit stay secure in the chuck
- Jobber length: 2-3/4-inch flute length and 4-inch overall length
Because cobalt hardness is uniform through the material, these bits can be repeatedly sharpened as needed, making them a good fit for users who prefer maintaining bits rather than replacing them.
