Description

Engineered around the operating needs of surface and underground drilling equipment, the Piston (OEM HD612-01101) is an aftermarket component 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.

Cross-reference data lists applications including HCR 12; final fit should be confirmed against the machine configuration or serial information. Accurate fit and robust working surfaces help maintain energy transfer and alignment through the high-frequency load cycles produced during drilling. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel.

Delkom combines rock-drilling spare-parts expertise with broad export capability for mining and tunneling customers. For purchasing support, bulk requirements or fitment confirmation, use Delkom reference 130 100 858 and OEM reference HD612-01101.
