Piston

The Piston (OEM HD712-01101) is a precision-made alternative spare part for rock drills and drifter equipment used in the most challenging mining and tunnelling environments. It is the central component that turns hydraulic pressure into the powerful percussive blows used to break rock, so its precision and finish directly affect drilling output.

Made from premium hardened steel with precision-ground impact and guide surfaces, it endures severe cyclic loading while holding tight clearances for efficient energy transfer. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
