Irwin 16102 Unibit2MT Titanium Nitrate Coated 4-Millimeter to 12-Millimeter by 1/4-Inch Shank Step Drill Bit

This IRWIN Unibit #2MT Titanium Metric Self-Starting Drill Bit is ideal for drilling holes into thin materials, such as stainless-steel, copper, brass, aluminum, plastic and laminates. IRWIN drill bits use a single-flute cutting edge for greater control through steps. A hex shank on each drill bit helps prevent slipping in the drill chuck, while the SpeedPoint tip penetrates faster to minimize walking.
