Makita 643827-1 Brush Holder for Saw BJR182F

The Makita 643827-1 Brush Holder is an OEM (Original Equipment Manufacturer) replacement part designed for use in Makita 18V LXT reciprocating saws (models like BJR182, BJR182F, BJR182X, BJR182Z, etc.). Its primary job is to hold the carbon brush in the correct position, ensuring good electrical contact with the armature or rotor so that the motor operates properly. Over time, due to wear and tear, heat, and mechanical stress, the brush holder may degrade or fail; replacing this part helps restore motor function, reduce sparking, and maintain performance. It fits into the motor assembly of the reciprocating saw, and it is sold individually (without carbon brushes or the holder cap, which are separate parts).
