Unibit Step Drill Sets HSS #1,2 & 3
The IRWIN Unibit Step Drill Set HSS No 1,2 and 3 allows you to drill through various types of thin materials. This Irwin drill bit set has a three-flatted shank to help prevent slipping inside the drill chuck. It has a tip that self starts to prevent skidding and avoid the need for center punching. The single-flute cutting edge gives you more control when going through steps. The measurements of the Unibit step drill bits are permanently laser etched on the flute for convenient viewing year after year, so it’s always easy to find the bit you need.
