Original DeWalt NA611431 — Spring assembly (spring SA) for the DCW620 series plunge routers. This small coil spring assembly restores the plunge/return action in the router’s plunge mechanism so the base returns smoothly and depth adjustments hold correctly.

Compatible with DeWalt DCW620H2 and DCW620NT 18 V 1/2" plunge routers (listed as NA611431 in the DCW620 Type‑1 parts diagram), so you can use it as a direct replacement when the original spring is worn or broken.

A genuine DeWalt spring assembly supplied as the single replacement part — an easy swap that gets your tool back to original ‑like plunge action. Keep this original DeWalt item on hand when working through power tool parts repairs for a quick fix.
