The WERA 05135009001 is a Phillips insert bit designed for use in power tools, impact drivers, and bit holders with a standard 1/4 inch hex drive. The bit features a No. 2 point size and measures 1 inch in overall length, making it well suited for compact fastening applications where clearance is limited. Built with a tough viscous treatment for universal use, this insert bit is intended for professionals who drive fasteners repeatedly across a range of materials and fastener head conditions. Electricians, HVAC technicians, plumbers, and general trade contractors will find this format common in daily service work.
This insert bit fits standard 1/4 inch hex bit holders and quick-change chucks found on cordless drills, impact drivers, and manual bit holders. The 1 inch OAL format is the most common insert length for bench-top and in-place fastening tasks across residential and light commercial service work. It is appropriate wherever No. 2 Phillips fasteners are encountered, including electrical panels, equipment enclosures, ductwork, and general mechanical assemblies.
Designed as a standard 1/4 inch hex drive insert bit compatible with any bit holder, screwdriver handle, or power tool chuck accepting the 1/4 inch hex insert format.
Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit damage. Inspect the bit tip for wear before each use, as a worn Phillips tip increases the risk of fastener head damage. Always ensure the driver and fastener point size match before driving. Replace worn bits promptly to maintain fastener integrity and reduce hand fatigue.
