The Irwin UNIBIT 20M HSS step drill bit drills holes up to 24 mm in diameter in sheet steel, brass, copper, aluminium, wood and plastic. The single flute helps produce round holes and can also be used for deburring.
The steps are laser-marked inside the flute. The SpeedPoint tip allows drilling up to 6 times faster than the standard model. Pilot drilling is required, as the bit has no centring point.
