Description

TUSK HSS STEP DRILL BITS Used to drill holes or enlarge holes in non-ferrous metals, sheet steel, plastic and stainless steel up to 3mm thick. Precision ground, spiral-flute design cuts faster with less vibration for clean & accurate burr free holes. Also features a self-centering point which eliminates the need to pre-punch.

Available in 2 options - both are manufactured using premium M2 High Speed Steel. The 'Bevelled Straight Shank' design guarantees stability in the chuck and designed for use on a standard drill, and the 'Quick Change Hex Fit' designed to be run on Impact Drivers - with a Titanium Nitride (TiN) coating that reduces heat for longer life and extra wear resistance.
