YH65 YH70 Chuck 51533073 is a component of the rock drill rotation system. It holds and drives the drill shank, transferring rotational force from the rotation mechanism to the drill steel during drilling operations.
Manufactured by ONSAMAK from wear-resistant steel, the 51533073 chuck is designed to handle rotational loads and repeated contact with the drill shank. It is supplied as an aftermarket replacement part for use in mining, quarrying, and construction drilling equipment.
