The Makita 638500-6 Brush Holder Unit is a genuine OEM spare part designed to restore reliable electrical contact in Makita SDS-Plus rotary hammers, including the HR2230, HR2460, and HR2470. Constructed from heat-resistant engineering plastic with robust metal contacts and terminals, the holder securely locates the carbon brushes and maintains the correct pressure against the commutator. This precise fit ensures consistent power delivery and helps reduce arcing, overheating, and premature brush wear — all common consequences of a degraded or damaged holder. As a genuine Makita component, the 638500-6 is a direct, like-for-like replacement that requires no modification to the tool. It is equally suited to scheduled servicing or fault diagnosis and repair, making it a practical addition to any maintenance routine on site. The holder performs reliably under the demanding conditions typical of trade use — including dust, vibration, and frequent start/stop cycling. Keeping this component in good condition helps protect the motor and extend overall tool life, supporting dependable drilling and chiselling performance in masonry and concrete.
