Wera 05056525001 Phillips Insert Bit No. 3 1/4 in Drive

Product Description

The WERA 05056525001 is a No. 3 Phillips screwdriver insert bit designed for use with 1/4 inch drive power tools and hand tool bit holders. With a 1 inch overall length, this insert bit is built for use in tight spaces and high-torque fastening applications. WERA constructs the bit with a ductile and tough material profile, helping it resist cam-out and deformation under repeated use. This type of insert bit is commonly used by electricians, HVAC technicians, plumbers, and general trade professionals who rely on bit drivers during equipment installation and service work.

This No. 3 Phillips insert bit is suited for driving larger Phillips-head fasteners found in electrical panels, HVAC cabinet assemblies, junction boxes, and mechanical equipment enclosures. The 1/4 inch drive shank fits standard bit holders, magnetic bit extensions, and quick-change chucks on cordless drills and impact-rated drivers. Its short 1 inch OAL makes it practical for confined access areas where longer bits cannot seat properly.

Installation Notes

Insert bits should be seated fully into the bit holder before driving fasteners to prevent slippage or tip damage. Verify that the bit tip engages the fastener recess fully before applying torque. Replace worn or chipped bits promptly, as damaged tips increase the risk of cam-out and fastener head damage. This is a consumable accessory and does not require special tools for installation.
