Wiha 66990 MagicRing Metric Ball End Hex L-Key Set
The Wiha 66990 is a premium 9-piece metric hex L-key set designed for professional mechanics, technicians, and field engineers. Housed in a convenient ErgoStar turn-select holder, these keys are constructed from high-quality tool steel and feature a corrosion-resistant chrome-plated satin finish.
This specialized set features Wiha's MagicRing technology on sizes 3.0mm and larger, utilizing a steel spring compression ring to securely hold screws in place during installation or removal.

Each blade is CNC precision machined with chamfered ends for reduced cam out and an exact fit.
