Bosch Phillips Impact Bits PRO PH2 55mm Pack of 15

The Bosch PRO Impact Control Torsion Phillips Screwdriver Bits are heavy-duty PH2 bits engineered for demanding screwdriving applications where standard bits fail under pressure. Constructed from heat-treated modified steel, these bits deliver exceptional strength and resistance to high torque. They are claimed to be up to 50x more robust than the Bosch Extra Hard bit, making them a reliable choice for installers and contractors working with impact drivers and drill drivers. The extended torsion zone is the key to their durability - rather than snapping under stress, the bit flexes and absorbs torque at the tip, significantly reducing the risk of breakage during heavy-duty use. Colour-coded rings indicate the head type at a glance, while laser markings allow for quick size identification, helping tradespeople work efficiently on site. With a 1/4" impact-rated hex shank, these bits are compatible with standard impact drivers and drill drivers, making them a practical addition to any pro
