Original Makita 638921-2 — brush holder / endbell complete for Makita grinders and shears. This replacement assembly restores the brush mounts and endbell on affected tools so the armature and brushes sit and contact correctly.
Fits (direct-replacement for) common Makita models including BGA450, BGA452, DGA452, BGD800 (DDG800) and the BJS-series shears (BJS160, BJS161, BJS101). Makita parts diagrams show this part used as the brush-holder / endbell on these models.
What you’re getting: the original Makita plastic/metal brush-holder/endbell assembly with two brush slots and spring clips/terminals ready to accept the correct carbon brushes. It is supplied without carbon brushes (replace the brushes separately if needed); the brush types commonly used in these tool models include Makita CB-430 and CB-438.
Quick install notes (so you know what to expect): it replaces the broken or worn brush carrier and endbell in-place — keep the brush springs and terminals aligned and reuse any original mounting screws. The part is an original Makita component and matches the parts diagrams for the listed models.
