DeWalt 942930-00 — Lock / spindle for plunge routers

Keep your router working like new: this original DeWalt lock (part number 942930-00) is the spring-loaded spindle lock that secures the router’s shaft during collet/bit changes. It installs into the collet housing and works together with the clamp lever and internal spring to hold the armature stationary while you tighten or remove the collet nut. This is the exact replacement used in DeWalt plunge routers that require the locking mechanism.

Physical note: the replacement is a compact lock / spindle component — vendor specs list approximate external dimensions of about 18 × 36 × 20 mm ; check your parts diagram to confirm fit before installing. The lock is shown in the DW625 parts breakdown alongside the related spring (942909-00) and collet-nut / collet components, so it swaps in directly where the factory unit sits.

Example models this part fits: DeWalt DW625 , DW624, DWE625 , DW629 and DeWalt MOF131 / MOF177 routers. If your parts diagram shows 942930-00 as the lock / spindle, this original DeWalt piece will restore the locking action.

Simple to install and sized to replace the factory component, this genuine DeWalt lock/spindle gets your router back to safe, reliable collet operations.
