Product description

Product Description

The IRWIN Unibit #1M High-Speed Steel Metric Hole-Enlarging Step Drill Bit is ideal for drilling holes into thin materials, such as stainless-steel, copper, brass, aluminum, plastic and laminates. Each drill bit uses a single-flute cutting edge that gives a true, round hole and provides greater control through steps. The hex shank helps prevent slipping in the drill chuck. The #1M drill bit creates 4mm to 12mm holes with 9 steps.
