The Makita 643700-5 Brush Holder Cap is a genuine OEM spare part for the Makita 2414B and 2414NB abrasive cut-off saws, designed to secure the carbon brushes within the motor's brush holder assembly. This screw-in cap maintains the correct spring pressure on the carbon brushes, ensuring a consistent and reliable electrical connection to the commutator. Constructed from hard-wearing moulded material with a precisely formed thread, it is built to withstand the demanding conditions of both site and workshop environments. A worn, cracked, or missing brush holder cap can allow dust and debris to enter the brush holder, leading to intermittent running, accelerated wear on the armature and commutator, and ultimately premature motor failure. Replacing this component as part of routine maintenance helps protect the motor internals and restore stable, reliable tool performance. As a genuine Makita replacement part, the 643700-5 offers a like-for-like fit on the listed machines with no modification required. Installation is straightforward — the cap simply screws into place without the need for specialist tools, making it well suited to fast turnarounds on busy sites and reducing costly downtime for contractors and professional users.
