Original Makita brush holder — part no. 644503-0 — a genuine Makita carbon brush holder designed for the 2×18 V (36 V) / 190 mm cordless circular saw DHS710 and closely related variants.
The unit secures a single motor carbon brush with an integrated spring contact and mounting tabs; the housing is heat‑resistant polymer with metal contacts to maintain steady electrical contact to the commutator and reduce sparking.
This listing is for one side (one brush holder); the matching opposite holder is part number 644504-8, so check both sides if the motor has been running hot or showing heavy arcing.
Fits the DHS710 so it installs as a direct, drop‑in replacement without modification.
A compact, reliable repair part to keep in your Makita spare parts kit — one of those small but critical power tool parts that restores proper motor contact and helps prevent further commutator damage.
