Wiha 71139 Power Hex Bit Holder 1/4 in Hex Drive

Product Description

The WIHA 71139 is a power hex bit holder designed for use with 1/4 inch hex shank power bits in impact drivers and drill/drivers. Built from steel, this holder accepts standard 1/4 inch hex drive bits and provides a secure, positive connection during high-torque power tool operation. The 4 inch overall length adds reach in tight spaces without sacrificing stability. It is a straightforward accessory for electricians, HVAC technicians, plumbers, and general trade professionals who rely on power tools for fastening tasks on the job site.

The WIHA 71139 is suited for residential and commercial applications where a 1/4 inch hex drive bit holder is needed for power screwdriving, drilling, or fastener installation. It fits standard 1/4 inch hex quick-change chucks found on most cordless and corded impact drivers and drill/drivers. The 4 inch OAL makes it practical for work in recessed panels, junction boxes, and other confined installation areas common in electrical, mechanical, and plumbing rough-in work.
