The Bosch PRO 8 Piece Impact Control Torx Bit Set delivers professional-grade performance for demanding screwdriving applications, built to handle high-torque impact driving without breaking. Manufactured from heat-treated modified steel, these Torx screwdriver bits are engineered for outstanding strength and durability. An extended torsion zone absorbs torque stress at the tip of each bit, protecting against breakage even under the most demanding conditions — making them well suited for installers, contractors, and tradespeople working with impact drivers on heavy-duty fixings. The set includes five Torx sizes (T15, T20, T25, T30, and T40), each featuring a 1/4" hex shank rated for use with both impact drivers and drill drivers. Colour-coded rings and laser-etched size markings make it easy to identify the correct bit quickly on site, reducing downtime and improving workflow efficiency.
