Bosch PRO Robust Line 6 Piece HSS-Co Drill Bit Set

The Bosch PRO Robust Line 6 Piece HSS-Co Drill Bit Set is a precision-ground twist drill bit set designed for drilling clean, accurate holes in stainless steel and other metals.

The cobalt content strengthens the cutting edge and helps maintain performance across repeated use, reducing the need for frequent bit changes on site. Each bit features a centring tip that prevents wandering at the point of contact, allowing you to start holes precisely without the need for a centre punch.

The cylindrical shank is compatible with standard three-jaw drill chucks, so no specialist tooling is requ
