Rockler High-Speed Steel Countersinks
Made from heat-treated high-speed steel, this countersink drill bit lets you quickly chamfer holes in wood, metal and other materials. It is ideal for countersinking holes to accept flat-head screws, and for chamfering or deburring the rim of a hole in wood, plastic or soft metals. The countersink features a single edge that is hardened and sharpened for highly efficient cutting action with little vibration, ensuring smooth results.
- Precision-ground HSS resists overheating for a more durable edge
- Sharpened point provides exact, instant centering and immediate cutting action
- Wide flute ejects chips quickly for less clogging
- Hex shank prevents slipping and can be used in keyed, keyless and quick-change chucks (see our optional Quick-Change Chuck #69015)
