Wiha 28188 32 Piece Interchangeable Bit Screwdriver Handle Set

Product Description

The WIHA 28188 is a 32-piece interchangeable bit screwdriver handle set built around a 1/4 inch drive cushion-grip handle. The set covers a wide range of fastener types including hex, Torx, Phillips, slotted, square, and nut driver applications. Bits are made from chrome-vanadium-molybdenum tool steel for durability under repeated use. The ergonomic soft-finish multi-component handle provides a comfortable grip during extended work. A ball bearing retainer locks blades in place during use, and the adjustable and reversible locking blade design adds versatility. The compact wallet organizer keeps the full set accessible on the job.

This set is suited for service technicians across HVAC, electrical, plumbing, and general mechanical trades. The 1/4 inch drive format and broad bit selection make it practical for panel access, equipment servicing, and tight-space fastener work. Torx coverage runs from T6s to T40s, Phillips from number 0 to number 6, and slotted from 3 mm through 6.5 mm. The chrome-plated finish resists corrosion in field conditions. The set includes 2 slotted bits, 5 Torx bits, 6 hex bits, 14 nut driver bits, 3 Phillips/slotted combination bits, square bits, and the handle, all stored in a compact wallet.
