Wiha 28199 Interchangeable Bit Screwdriver Handle 10 Pc

Product Description

The WIHA 28199 is a 10-piece interchangeable bit screwdriver handle set built for trade professionals who need versatility in a single ergonomic tool. The set centers on a Softfinish multi-component cushion grip handle with adjustable and reversible locking blades and a ball retainer hold to keep bits secure during use. Bits are manufactured from chrome-vanadium-molybdenum tool steel for durability under daily job-site loads. The handle features roll-off protection and is sized for a natural, comfortable grip across extended work sessions. This is a compact, organized solution for technicians who work across fastener types without carrying multiple dedicated drivers.

The WIHA 28199 is suited for residential and light commercial service work where multiple fastener types are encountered in a single job. Typical applications include HVAC equipment panels, electrical enclosures, plumbing access covers, and control board servicing. The set covers Torx sizes T6, T7, T8, T9, T10, T15, T20, and T25, Phillips sizes 1 and 2, slotted sizes 4 mm and 6 mm, and hex drive sizes from 3/32 to 3/16 inches. The included bits span two Phillips, two slotted, six hex, and eight Torx configurations.
