BRAND NEW IN CLAMSHELL

Unibit step drills from Irwin are the industry standard. Their single flute design results in a much more accurate hole than double flute bits. The SpeedPoint™ gets the hole started fast! Ideal for drilling holes in thin materials such as mild steel, copper, brass, aluminum, plexiglass, wood and laminates. Models designated with a T offer a TiN (Titanium Nitride) coating which hold their cutting edge up to six times longer!
