Wera 05059755001 PH1 Phillips Power Screwdriver Bit 1/4 in Hex

Product Description

The WERA 05059755001 is a PH1 Phillips power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. Built to the PH1 specialty point size, it delivers precise engagement on Phillips head fasteners in production, assembly, and service applications. The bit measures 2-3/4 inches overall length and features a 4.50 mm body diameter, giving it the reach and rigidity needed for repetitive power driving. This is a professional-grade bit suited for electricians, HVAC technicians, plumbers, and general trade professionals who drive Phillips fasteners daily with power tools.

This bit fits standard 1/4 inch hex quick-change chucks found on cordless drills, impact drivers, and electric screwdrivers. The PH1 point size is commonly used on smaller fasteners found in electrical panels, control boards, junction boxes, access covers, and light-gauge sheet metal applications. The 2-3/4 inch overall length provides additional reach in recessed or hard-to-access fastener locations without requiring an extension. It is sold individually with a minimum order quantity of 5 units, making it practical for stocking service trucks and toolboxes.

Installation Notes

Insert the bit fully into the 1/4 inch hex chuck until it seats and locks before driving. For impact driver use, verify the bit is rated for impact service to avoid premature fracture. When driving into sensitive components such as control boards or terminal blocks, use a clutch-controlled drill setting to prevent overtorque and fastener damage. Replace bits showing visible wear on the tip profile to avoid cam-out and fastener head damage.
