Bosch 1609B00458 — Genuine Bosch Quick‑Lock. This small replacement quick‑lock/lever assembly restores the slide‑lock function on Bosch sliding and compound mitre saws, letting the saw carriage be locked for transport or fixed during setup exactly like the original Bosch part.

Fits (examples): GCM12SD, GCM12MX, GCM18V‑08 (3601M41010), CM12, CM10GD, CM8S / GCM8 SDE and several other Bosch mitre/slide saw variants that use the same Quick‑Lock part number 1609B00458. Confirm your tool’s 10‑digit version number from the side of the machine against the part number before ordering.

Notes for repair: this is the original Bosch replacement Quick‑Lock (same form and fit as the factory part) designed to install in the same mounting location and use the existing fasteners and linkage on compatible Bosch saws. If your saw’s locking lever is worn, broken or missing, this genuine Bosch part returns the original locking action without modification.
