Titanium Coated Step Drill Bit 4-22mm

Create accurate holes or enlarge existing holes in metals up to 10mm thick with this step drill bit. Suitable for use with steel, non-ferrous metals and hard plastics, the drill has clearly-marked 2mm graduations from 4-22mm.
A precision ground, multi-flute cutting edge delivers burr-free holes, while a self-centring point eliminates the need to pre-punch. The bit’s TiN coating gives it extra wear resistance, making it a firm favourite among trade professionals.
