Bosch PRO Robust Line 13 Piece HSS-Co Drill Bit Set

The Bosch PRO Robust Line 13 Piece HSS Co Drill Bit Set is a professional grade metal drill bit set designed specifically for drilling in stainless steel and other metals. Manufactured from high speed steel blended with 5% cobalt HSS Co, these bits deliver excellent heat and wear resistance essential when working with tough materials such as stainless steel. The cobalt content reinforces the cutting edge, helping the bits maintain performance through extended use on demanding jobs. Each bit features a precision centring tip that prevents wandering when starting a new hole, enabling accurate, clean results from the first contact. This makes them a practical choice for construction workers, installers, and contractors who need reliable, repeatable performance across a range of hole sizes. The set includes 13 bits covering diameters from 1.5mm to 6.5mm, all with a cylindrical shank compatible with standard three jaw drill chucks. Presented in a compact Robust Line case, the set keeps bits organised and protected on site.
