## Description

The Makita 643710-2 Brush Holder Cap is a genuine OEM replacement part designed to seal and protect the carbon brush holder on heavy-duty Makita demolition hammers and cutters. Made from a durable, heat-resistant polymer, this cap keeps dust, debris, and moisture out of the brush chamber during demanding site use. Its screw-in design allows for straightforward removal and refitting, making it well suited to routine servicing and brush replacements without specialist tools or modification. A worn, cracked, or missing brush holder cap can compromise brush contact, leading to arcing, uneven brush wear, and reduced motor performance. Fitting a genuine replacement restores the original seal and helps maintain consistent power delivery under the sustained vibration and impact loads typical of demolition work. This part is a direct fit for the Makita HM1800 and HM1810 demolition hammers, and is also compatible with selected Makita cutters including the 4112HS and 4114S. Using a genuine Makita part (MPN 643710-2) ensures correct fit without adaptation and supports long-term tool reliability on site.
