High-speed steel provides enhanced hardness and wear resistance, enabling the bit to maintain its sharpness over extended use. This results in cleaner cuts and reduced chipping, especially when working with harder materials.

The titanium nitride (TiN) coating lowers friction during drilling, which enhances both cutting efficiency and tool life. This means less heat build-up and extended operation without the need for frequent bit changes.

Yes, the 1/4 hex shank design allows compatibility with a variety of drill types, including electric, cordless, and impact drills, making it a versatile addition to your toolkit.
