In daily use

These countersinks are designed for high-performance applications, including dry machining and hard-to-machine materials. The cylindrical shank fits standard drill chucks, allowing use in drill presses, hand drills, and machining centers. The TiAlN coating reduces friction and improves chip flow, resulting in smoother finishes and longer intervals between sharpening.
