The WIHA 72522 is a Phillips screwdriver insert bit designed for use with 1/4 inch hex drive tools. It carries a Number 2 point size and measures 25 millimeters in overall length. The bit is machined to an exact-fit tip profile and is through-hardened steel for extended service life under repeated torque loads. Electricians, HVAC technicians, and general trade professionals use insert bits like this one when working with power screwdrivers, impact drivers, or bit holders on panelboards, equipment enclosures, and fixture installations.
This insert bit is suited to residential and light commercial applications where a standard 1/4 inch hex drive is the platform of choice. The Number 2 Phillips profile covers the most common fastener size encountered in electrical boxes, HVAC cabinet screws, and general mechanical assemblies. The through-hardened construction helps resist cam-out and tip deformation during high-cycle use. It is sold in a package quantity of 30 bits, making it a practical bench or van-stock item for trade professionals who go through consumable bits regularly.
Designed for use with any 1/4 inch hex drive bit holder, power screwdriver, or impact driver accepting standard insert-style bits.
Insert bits should be seated fully into the bit holder before applying torque. Inspect tip condition before each use and replace bits showing visible wear or rounding at the tip profile. When used with an impact driver, confirm the bit holder is rated for impact use to avoid premature bit failure.
