The WERA 05056662001 is a No. 2 Phillips insert bit designed for use with 1/4 inch hex drive power tools and hand drivers. It measures 1 inch in overall length, placing it in the standard insert-bit class for use in bit holders, quick-change chucks, and inline screwdrivers. Built from a ductile, tough-viscous steel formulation, this bit is engineered to resist cam-out and torsional fracture under repeated fastening cycles. Electricians, HVAC technicians, and other trade professionals who rely on power-assisted fastening will find this bit suited for high-repetition screw-driving tasks where bit longevity and torque transfer matter.
This insert bit is a fit for residential and light commercial trade work where No. 2 Phillips fasteners are common - panel covers, equipment enclosures, junction boxes, sheet metal screws, and similar applications. Its 1 inch OAL is optimized for use in bit holders or magnetic bit extensions rather than direct chuck use. It is sold individually with a minimum order quantity of 10 units, making it practical for stocking job boxes or service vans.
Designed as an OEM-style replacement insert bit compatible with any 1/4 inch hex drive bit holder, screwdriver handle, or power tool chuck accepting standard 1 inch insert bits.
Insert bits should be seated fully into the bit holder or magnetic chuck before applying torque. Always de-energize or unplug power tools before swapping bits. Inspect the bit tip for wear or rounding before each use - a worn Phillips tip increases cam-out risk and can damage fastener heads. No specialized tools or trade licensing are required for bit replacement.
