NA121486 supersedes older part numbers: N435943

Original DeWalt NA121486 — Carbon brush pair built to restore reliable motor contact in small DeWalt angle grinders. These graphite/ carbon brushes replace worn brushes that cause intermittent power, sparking, or reduced torque and are sold as a matched pair so both sides of the commutator wear evenly.

Key details: rectangular carbon brush blocks with nominal dimensions around 6.5 × 12 × 14 mm (initial brush length ~14 mm), fitted with the usual spring/contact arrangement for easy replacement. This matches the original brush length specification for the DWE4206 series.

Fits (example models): commonly used in DeWalt DWE4206 angle grinders (including DWE4206K variants) and is listed as compatible with several DWE-series small grinders such as DWE4202 and DWE4204 on parts diagrams — check your tool’s type label to confirm fit.

Why buy it: a simple, direct replacement to get your grinder running like new again — a genuine DeWalt part number NA121486 that keeps your tool performing to spec. For best results replace both brushes together and inspect the armature/commutator for scoring or debris before reinstalling. This is a common maintenance item among DeWalt parts and a straightforward repair in the range of routine parts for power tools.
