It is engineered for direct fitment in the specified Makita drills, aligning with the existing motor housing, bearings, brushes and field coil without modification. Suitable for tradespeople and DIY users, this OEM armature helps maintain tool efficiency and extends service life under regular on-site or workshop use.
