Wera 851/1 PH Impaktor Phillips Screwdriver Bits

This variant is the Wera 851/1 PH Impaktor bit in PH2, 25mm, supplied in a pack of 10. The PH2 is the most universally used Phillips profile, making this an essential bit for general construction, joinery, decking, and everyday trade use. The 25mm length keeps things compact and manoeuvrable in restricted spaces. Wera's Impaktor technology is at the heart of these bits, engineered to withstand the punishing torque and shock forces produced by impact drivers — extending bit life well beyond what standard bits can offer. The diamond-particle coating on the tip grips the screw head securely, biting in to prevent the frustrating slippage and cam-out that can damage both bit and workpiece. Colour-coded for effortless identification on site.
