Makita 453129-5 — Grip Base (original Makita)
Replacement grip base that forms the collar for the auxiliary (side) handle on selected Makita SDS‑plus rotary/combination hammers. The part is a moulded, impact‑resistant polymer collar in black that locates and stabilises the side‑handle assembly, and it mates with Makita grip 158057‑6 and secures with an M8×90 hex bolt (part 266745‑2).
Fits (examples): DHR243 / DHR242 series (including DHR242RFE / DHR242Z), BHR242 / BHR243 and HR2650 rotary hammers — listed in Makita parts diagrams for those models.
Why this part helps: if the side‑handle collar on your hammer is cracked, loose, or missing, this genuine Makita grip base restores correct alignment and secure clamping for the auxiliary handle so you can safely control the tool during drilling or chiselling.
(Part number: 453129‑5 — original Makita fitment.)
