Genuine DeWalt carbon motor brush (part number 580017-01) — a direct-fit replacement carbon brush with insulated lead wire and molded connector designed for DeWalt plunge routers. This single brush installs into the motor’s brush holder and restores consistent commutator contact and motor performance; it’s recommended to replace brushes in pairs for best results.

Common fits include DeWalt DW621 series routers (multiple Type/variant suffixes) and several DW620/DW622 router models, so it’s a likely match if your router is one of those models.

Sold per brush (lead wire attached), this original DeWalt spare parts item is compact, simple to fit, and a standard maintenance item when a router starts smoking, sputtering, or losing power under load.

If you need a straightforward replacement of essential power tool parts to get a router back to reliable operation, this genuine DeWalt 580017-01 brush is the specific component technicians commonly use for the DW621/DW620/DW622.
