Wiha Phillips PH1 25mm Hex E6.3 krom-vanadij bit 22509

Driving Phillips screws with a standard 1/4" hex power bit can be frustrating when the tip slips or wears quickly, damaging screw heads and slowing work. The Wiha Phillips PH1 bit solves this with a precision-machined tip that seats securely in PH1 fasteners, reducing cam-out and protecting both the screw and the bit. Made from high-quality chrome-vanadium steel and through-hardened for durability, it withstands the torque of power tools while maintaining its shape over many uses.
