Makita 136312-6 — Tool Holder Assembly (original Makita). Direct-replacement tool holder assembly for Makita rotary hammers (listed as TOOL HOLDER ASS'Y, part no. 136312-6), designed to restore secure SDS‑Plus bit retention and correct engagement with the hammer mechanism.
Fits models including HR3001C and HR3011FC and HR008G that use the same SDS‑Plus holder, so it mates with SDS‑Plus bits (10 mm shank) used in those 30 mm class combination hammers.
This genuine Makita tool holder assembly comes as the complete holding sleeve and locking components (ready to drop into the gear / hammer housing), returning proper bit seating and consistent hammer / rotation transfer — ideal when the original holder shows wear, excessive play, or damaged locking grooves. Makita parts are manufactured to the same tolerances as the factory-installed component.
If you need a reliable replacement to get your drill back to spec, this original Makita 136312-6 is the exact partshown for these models and is counted among common power tool parts for SDS‑Plus rotary hammers.
