Wera 851/1 PH Impaktor Phillips Screwdriver Bits

This variant is the Wera 851/1 PH Impaktor bit in PH1, 25mm, supplied in a pack of 10. The compact 25mm length is ideal for use in tight spaces and confined access points where a shorter bit gives greater control, and the PH1 profile suits smaller Phillips screws commonly found in cabinetry, electronics housing, and precision joinery work. Built around Wera's Impaktor technology, these bits are purpose-designed for impact drivers, absorbing the high-torque shock loads that would quickly destroy standard bits. The rough diamond-particle coating on the tip bites into the screw head, eliminating slippage and cam-out for cleaner, more reliable drives. Colour-coded for quick identification, these bits are a professional staple for any trade kit.
