Hitachi 310-124 Spare Part - Handle Damper

Original Hitachi handle damper — part no. 310‑124 — a molded rubber/elastomer cushion that sits in the side/handle assembly to absorb shock, reduce vibration transfer to the user and prevent metal‑on‑metal wear in demolition/rotary hammers.

This genuine Hitachi replacement is referenced in Hitachi parts lists and fits a range of demolition and rotary‑hammer models, for example H45MA, H45MR, H45MRY, H45SB2, H60MRV, DH40MRY, DH45ME, H65SD3 and H70SA (confirm the part number against your tool’s parts diagram to be certain).

Small, resilient and simple to fit (push‑in/seat into the handle assembly), the 310‑124 handle damper restores handle isolation and extends the life of nearby components; it’s a common item listed among Hitachi spare parts for demolition hammers.

If your tool shows a cracked, hardened or missing rubber damper, replacing the 310‑124 is a low‑cost repair option that settles rattles and vibration — a straightforward, direct replacement listed in parts diagrams and useful when you only need a single component to get the tool back to working order. This is one of the small, specific parts for power tools that directly affects comfort and service life.
