Carbon brush set with part number N039389, is a precise replacement motor brush suit for Dewalt,  including the, 14″In Pipe Cutter and several closely related models. These brushes are essential for the electrical operation of universal motors found in these grinders, providing reliable conductivity between the stationary field windings and the rotating armature under load.

Manufactured from high‑quality carbon/graphite composite, each brush is engineered to maintain stable electrical contact with the commutator while resisting wear and heat from continuous motor operation. Over time, carbon brushes wear down naturally; replacing worn brushes with this genuine or high‑quality equivalent set ensures your grinder maintains torque, reduces motor sparking, and delivers consistent performance.

Product Dimension – 18 x 16.50 x 6.50 M.M.
Application – 14″In Pipe Cutter
Part No. – N039389
