Chuck

The Chuck (OEM 550 520 91) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It grips and drives the drill rod or shank adapter, transmitting rotation and percussion to the drill string while maintaining secure alignment.

Manufactured from hardened, wear-resistant alloy steel, it withstands high torque and impact loads while preserving accurate centring and long service life. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.
