Makita Genuine 136312-6 Tool Holder Assembly for Makita HR3001C Rotary Hammer

The Makita Genuine 136312-6 Tool Holder Assembly is a genuine OEM replacement part designed specifically for the Makita HR3001C rotary hammer, restoring precise bit retention and reliable power transfer.

This assembly replaces the complete front tool-holding mechanism that interfaces directly with the bit shank. Manufactured to factory tolerances, it is built from hardened metal components engineered to withstand the demands of heavy site use and regular workshop maintenance schedules.

The integrated sealing elements help limit dust ingress, protecting internal mechanisms in gritty or dusty working environments — a practical consideration for contractors working with masonry, concrete, or block. Firm bit retention reduces vibration and the risk of unplanned bit release, supporting both drilling and chiselling operation modes.

As a genuine Makita part, the 136312-6 offers assured compatibility with the HR3001C, helping to maintain the tool's original performance, user safety, and service life. It is a straightforward replacement using basic hand tools, making it well suited to proactive maintenance programmes and reactive repairs alike, minimising costly downtime on site.
