Makita 455502-5 Spare Part - HANDLE BASE A

Original Makita Handle Base A — part 455502-5 — replacement handle support for Makita breaker hammers. Fits the HM1812 series (listed also as HMJ1812 on some parts diagrams) and installs as the drop-in handle base that secures the fixed handle and helps isolate vibration from the main housing.

This genuine Makita component is sold as the single handle base (also referenced as 4555025 on some listings) and is designed to restore proper handle alignment and vibration absorption so the breaker performs and feels like it should. Ideal when you need a correct-fit part to finish a repair; it’s one of the power tool parts you’ll want to replace if the original handle base is cracked, worn, or loose.
