The Draper HSS Step Drill Bit is a versatile cutting tool designed for drilling precise holes in multiple materials including steel, brass, copper, aluminium, wood and plastics. Manufactured from high-speed steel and correctly hardened, this step drill bit delivers reliable performance and extended service life across demanding applications. This stepped drill bit features 2mm increments with clearly marked graduations from 4mm through to 30mm, eliminating the need for multiple drill bits when creating various hole sizes.
The progressive step design allows tradespeople to drill and enlarge holes in a single operation, making it particularly useful for electricians installing cable glands, plumbers working with pipework, and engineers preparing mounting holes in sheet metal. The high-speed steel construction ensures the cutting edges maintain their sharpness even when working with harder materials such as steel and brass. Each step graduation is clearly marked on the bit itself, enabling accurate hole sizing without constant measurement and reducing the risk of drilling oversized holes in precision work.
