This variant of the Bosch PRO Impact Control Torsion Pozidriv Bit is a PZ3, 55mm bit supplied in a pack of 2. Combining a PZ3 head for large-screw applications with a 55mm length for additional reach, this bit is well suited to structural timber, decking, and heavy-duty installations where both torque capacity and bit depth are important. The longer format is particularly effective when driving screws through thicker materials or accessing fixing points that a standard 25mm bit cannot comfortably reach. The twin-pack provides a practical spare for continuous use on site. Manufactured from heat-treated modified steel with an extended torsion zone, these bits are built to withstand the most demanding screwdriving tasks without snapping. Up to 50x more robust than the Bosch Extra Hard Bit (2607001528), with a 1/4" impact-rated hex shank. Features and Benefits: • Up to 50x more robust than Bosch Extra Hard Bits for exceptional durability • Heat-treated modified steel for superior strength under high-torque conditions • Extended torsion zone prevents tip breakage during heavy-duty use • 1/4" impact-rated hex shank compatible with impact drivers and drill drivers • Colour-coded rings and laser markings for quick and easy identification Specifications: Head Type: PZ3 Length: 55mm Pack Quantity: 2 Contents: • Pack of 2
