Description
Created for continuous-duty rock drilling applications, the Piston (OEM HD712-01101) offers a service-focused replacement choice for the percussion and drifter assembly. The component supports the percussion or tool-retention sequence, helping transfer drilling forces while keeping the working assembly correctly aligned.
For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing. Typical listed applications include HCR 12-S and HCR 1200-DS, subject to machine specification and configuration verification. The geometry is intended to remain stable under repeated impact loading, supporting reliable interaction with the adjacent drifter components.
