Wiha 77792 1/4 in Drive Bit Screwdriver Set 26 Piece

Product Description

The WIHA 77792 is a 26-piece, 1/4 inch drive bit screwdriver set built for trade professionals who need the right fastener tip available fast. The set covers four tip types — Hex, Phillips, Slotted, and Torx — making it a practical all-in-one driver solution for HVAC, electrical, plumbing, and general mechanical work. Bits are hardened and tempered CVM tool steel, precision machined for an exact fit. The ergonomic cushion grip handle reduces hand fatigue during extended use, and the spring-driven pop-up cartridge with quick-release locking bit holder keeps the selected bit secure and allows rapid swaps on the job.

This set suits residential and light commercial service environments where a technician needs access to a wide range of bit types without carrying multiple individual drivers. The spring-driven pop-up cartridge stores all 26 bit tips in a compact, grab-and-go format. Torx coverage runs from T8 to T30, Phillips covers No. 1 and No. 2 points, Slotted covers 4 mm and 6 mm, and the 14 Hex bits round out the set. It is well suited for panel work, equipment installation, and routine service calls across multiple trades.

Installation Notes

Insert the selected bit tip into the quick-release locking bit holder until it clicks securely before applying torque. Inspect bit tips before use and replace any that show wear, rounding, or chipping to avoid fastener damage. When servicing energized equipment, always de-energize and lock out the circuit before using driver tools inside panels or enclosures per applicable NEC requirements.
