DeWalt N031214 Brush & Holder Assembly Tool Replacement Parts for Drills DCD985 DCD980

The DeWalt N031214 Brush & Holder Assembly is a vital factory-spec motor maintenance component developed exclusively for heavy-duty cordless hammer drills and drivers. This complete kit houses the mechanical carbon blocks and tension springs needed to maintain continuous electric contact with the spinning armature commutator. By delivering a steady stream of electrical current, the assembly ensures optimal torque transmission, stable rotational speed, and reliable electric braking performance during challenging drilling applications. Over time, carbon contacts naturally erode due to friction, which can lead to intermittent power losses, reduced overall drilling efficiency, or a complete failure to turn on. Replacing your degraded motor brushes with this premium module quickly restores consistent electrical flow and shields the inner motor from destructive arcing damage. Built with highly conductive carbon formulations and a rigid, temperature-resistant housing frame, this component is designed to survive high-vibration conditions and continuous construction work. For safety, always remove the lithium-ion battery pack from the tool chassis and wear appropriate eye protection before opening the casing to execute this component replacement
