Wiha 79246 Hex Bit Set 11 Piece 1/4 Inch Drive

Product Description

The WIHA 79246 is an 11-piece hex bit set designed for use with standard 1/4 inch drive bit holders and power tools. The set covers a full range of inch hex sizes from 1/16 inch up to 1/4 inch, making it a practical bench and field option for technicians who work across multiple fastener sizes without swapping toolboxes. Each bit measures 25mm in length and the set ships in a plastic holder that keeps bits organized and accessible on the job. It also includes a Wiha 71131 universal magnetic insert bit holder to extend reach and improve bit retention during use.

This hex bit set is suited for HVAC, electrical, and general mechanical service work where hex-head fasteners are common. It is equally at home in a service van or a shop environment. The plastic holder organizes bits by size so technicians can grab the right bit quickly during installation or maintenance tasks. The included magnetic bit holder adds utility when working in tight panels or enclosures where standard-depth access is limited.

Installation Notes

Hex bits should be fully seated in the bit holder before applying torque to avoid cam-out or fastener damage. When using with a power driver, set the clutch to an appropriate torque level for the fastener and material to prevent stripping. Inspect bits for wear or rounding before use, particularly on critical fasteners inside electrical panels or HVAC equipment where damaged fasteners create service delays.
