Irwin PRO 10 Pieces Metal HSS Drill Bit Set

Discover the versatility and durability of the IRWIN Tools HSS PRO drill. These bits measure 1.6mm x 43mm and have a working length of 20mm. HSS Pro Series drills are designed for drilling steel and steel moldings, alloy and non-alloy steels, cast iron, non-ferrous metals, plastics and other materials. A 118 slotted tip shape provides optimal centering when starting and a faster drilling rate that requires lower feed pressure than standard HSS drills with a beveled edge. The high elasticity of this HSS drill ensures a low risk of breakage even when drilling with smaller diameters. Tight tolerances and high concentricity allow maximum drilling accuracy.
