Description
Overview:
This genuine Hitachi/Hikoki ball holder is a small but essential service part used in the bit retention mechanism of compatible rotary hammers, including the DH 28PX and DH 28PMY. It supports the locking balls inside the tool holder so the drill bit engages correctly and stays secure under load. Built from robust metal with a durable black finish, it is designed for repeated impact and rotation in tough site conditions. As an OEM component (OEM No. 324528, replaces 322810), it offers the correct fit and geometry for consistent performance and long service life. Ideal for restoring smooth operation and preventing premature wear in the chuck/tool holder assembly, it helps keep your hammer drilling and chiselling efficiently in concrete, masonry, and similar materials.
