1/4″ Hex Shank 1/2 Irwin Unibit® HSS Fractional Step Drill
IRWIN® UNIBIT® step drill bits are ideal for drilling holes in just about any type of thin material. General purpose high speed steel UNIBIT step drill bits are perfect for use in mild steel, copper, brass, aluminum, plexiglass, wood, and laminate. Hole sizes are permanently laser-etched on the inside of the flute, so they can be easily identified throughout the life of the bit.
