The Bosch PRO 8 Piece Impact Screwdriver Bit Set is a professional-grade bit set designed for heavy-duty screwdriving with impact drivers and drill drivers. Built from heat-treated modified steel, these bits offer outstanding strength and resistance to high torque — making them a reliable choice for installers and contractors who demand performance under pressure. Bosch claim up to 50x greater robustness compared to the Bosch Extra Hard Bit (2607001528). The extended torsion zone is a key feature here, absorbing torque stress at the tip of the bit rather than allowing it to build to breaking point. This design helps prevent bit failure during demanding applications, extending working life significantly. Each bit features a colour-coded ring for quick head-type identification and laser markings for fast size selection — practical details that matter when you're working at pace on site. The set covers the most commonly used profiles: PH1, PH2, PZ1, PZ2, T15, T20, T25, and T30.
