Wiha 71994 38-piece Screwdriver Insert Bit Set

Product Description

The WIHA 71994 is a 38-piece screwdriver insert bit set covering five drive types: Hex, Phillips, Slotted, Square, and Torx. It is designed for use with standard 1/4-inch hex bit holders and power screwdrivers. The set includes a magnetic bit holder and a dual-material handle, making it suitable for both hand-driving and power-tool applications. Hex sizes range from 1/16 to 1/4 inch, Torx sizes span T-7 to T-40, and Phillips sizes run from 0 through 3. The non-rolling hex shape of the storage case keeps bits organized on the workbench. Electricians, HVAC technicians, and plumbers use sets like this when servicing equipment that requires multiple driver types in a single job.

This bit set suits a wide range of trade service applications where fastener variety demands multiple tip types in one kit. The inclusion of Pozidriv sizes 1, 2, and 3 makes it useful for imported equipment and European-manufactured components common in HVAC and electrical panels. The set is equally applicable on residential service calls and light commercial work where technicians carry a single organized kit rather than individual drivers. The included magnetic bit holder allows quick swaps between bit types without additional tooling.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit damage. When used in powered screwdrivers, select the appropriate clutch setting for the fastener size and material. Store bits in the provided case to prevent corrosion and maintain tip geometry. Inspect bit tips regularly and replace any showing wear to avoid fastener head damage.
