Bosch 35 Piece Drill and Screwdriver Bit Set for Metal

The Bosch 35 Piece Drill and Screwdriver Bit Set for Metal is a drill bit set designed for universal drilling and screw-driving. It combines screwdriver bits and HSS drill bits in one set, so you can switch between fixing and drilling without changing kit. The screwdriver bits are made from S2 Modified Steel with an optimised heat treatment process for extra-hard performance. A tapered torsion zone absorbs force and vibration, helping the bits cope with torque peaks. The bits are colour-coded, so the right type is quick to spot on site. The precision-ground HSS (high-speed steel) drill bits give a fast drilling rate in metal and plastics. All bits have a 1/4-inch external hex shank for use with screwdrivers and drill drivers. The set comes in a robust storage box that shows its contents clearly and keeps the bits safe in storage and transit.
