This IRWIN Unibit #4MT 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.
