Wiha 79243 Screwdriver Insert Bit Set 11 Piece

Product Description

The WIHA 79243 is an 11-piece screwdriver insert bit set covering three tip types: Phillips, slotted, and Torx. Designed for use with power tools, impact drivers, and manual bit holders, this set gives tradespeople a compact, multi-tip solution for panel work, fixture installation, and equipment service. The set spans Phillips sizes 1 through 3, slotted sizes 4.5 mm through 8.0 mm, and Torx sizes T-10, T-15, and T-20, making it suitable for a wide range of fastener heads encountered in electrical, HVAC, and general mechanical work.

This bit set is well suited for residential and light commercial service work where technicians regularly switch between fastener types. Electricians and HVAC technicians will find the Torx and Phillips coverage particularly useful for panel covers, equipment enclosures, and control box fasteners. The slotted bits extend usefulness to terminal screws and older equipment hardware. The compact 11-piece format keeps a full range of common drive sizes accessible without carrying multiple individual bits.

Installation Notes

Insert bits are installed and removed by hand into any compatible 1/4-inch hex bit holder or chuck.
