The Bosch PRO 8 Piece Impact Screwdriver Bit Set is a professional-grade mixed bit set designed for heavy-duty screwdriving with impact drivers and drill drivers. Built from heat-treated modified steel, these bits offer exceptional strength and resistance to high torque — making them a reliable choice for installers and contractors who put their tools through demanding, repetitive use. Bosch claim the bits are up to 50x more robust than the Bosch Extra Hard standard bit (2607001528). A key design feature is the extended torsion zone, which absorbs torque stress at the tip of the bit rather than allowing it to build to breaking point. This helps extend bit life significantly during high-impact applications. Each bit includes a colour-coded ring for quick head-type identification, alongside laser markings indicating the size — so you can grab the right bit without stopping to squint at the shank. The 1/4" hex shank is impact-rated for use in both impact drivers and drill drivers. The set covers the most commonly used drive profiles on site, including Phillips PH2, Pozi PZ2, Hex H5, and Torx T20, T25, and T30.
