Titanium drill bits offer twice the life cover of a standard HSS drill bit. Designed for use in the higher torque impact drill/drivers, they have an upgraded tip design for no-skate starts and a titanium cooling shield thanks to the titanium nitrate coating. The coating provides less friction and thus less generated heat. Excellent for the handyman and trade alike. This set contains 13 metric drills in a handy plastic case, sizes 1.5 - 6.5mm. Hang-sell.
