Wiha 72521 Phillips Insert Bit 1/4 Inch Drive 30 Pack

Product Description

The WIHA 72521 is a Phillips screwdriver insert bit engineered for demanding trade use. Sized at point 1 and built for a 1/4 inch drive, this 25 mm bit is manufactured from through-hardened steel for extended service life. The exact-fit machined tip reduces cam-out and tip wear during high-torque fastening work. Packaged in a 30-piece quantity, this insert bit suits electricians, HVAC technicians, plumbers, and other tradespeople who burn through bits on production work and need a reliable bulk supply on hand.

This insert bit is intended for use with 1/4 inch hex drive power tools, impact drivers, and bit holders commonly found on residential and light commercial job sites. The No. 1 Phillips point size handles smaller fasteners typical in electrical panels, junction boxes, equipment covers, and control assemblies. Through-hardened steel construction holds up to repeated use in high-cycle applications where softer bits deform quickly.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque. Inspect the tip for deformation or rounding before each use and replace worn bits to prevent fastener head damage. This product is installed by electricians, HVAC technicians, and general tradespeople as a consumable accessory.
