Product Information

Full details

The Bosch HSS Step Drill Bit is constructed from HSS (high-speed steel) for extended durability with coolant usage. It features laser-marked figures in spiral flutes for easily visible and robust hole diameter markings. The 3-flat shank ensures a secure grip in the chuck and enables powerful high-torque transmission. This drill bit allows for smooth, burr-free drilling across multiple diameters with a single tool, ideal for deburring, creating round holes, and enlarging existing ones. Its split-point tip eliminates the need for pre-punching, providing an easy start. The CNC-ground spiral flute optimizes chip removal and minimizes vibration for consistent drilling. Axial and radial relief grinding guarantee superior cutting performance and smoothness. It is suitable for thin materials including non-ferrous metals, sheet plastic, sheet steel, plastic, and stainless steel. Step diameter ranges from 6-39mm, with a step height of 4mm. The shank diameter is 10.0mm, and the total length is 93.5mm.
