Description
Overview:
The Tool Holder 142972-4 is a Genuine Makita part for the HR2601 Rotary Hammer Drill, and is also compatible with the DHR280ZJ. It is the front chuck/tool retainer assembly that secures the drill bit and transfers hammer energy accurately into the workpiece. Built with a hardened steel core and a durable protective nose boot, it is designed to withstand heavy site use and continuous impact loads. The holder keeps the bit centred and stable to reduce wobble and improve drilling precision. As a like-for-like service replacement, it restores correct fit and performance when the original holder is worn, contaminated, or damaged. It is intended for the bit interface used by these Makita SDS‐Plus rotary hammer drills, supporting reliable, safe bit retention during drilling and light chiselling tasks in masonry and concrete.
