TiAIN Coating: The industrial-grade TiAIN coating, with its exceptional hardness, gives the step drills a longer service life, higher machining speeds, and excellent heat resistance! This coating offers excellent resistance to heat, wear, and corrosion, as well as strong adhesion and low friction. Helpful Information: When using the drill for the first time, it is necessary to use cutting oil to allow the bit to start easily and reduce friction. As the bit is a wear part, it should be replaced regularly, especially if it has been subjected to heavy use.
