Description

Built for continuous heavy-duty service, the Damping Piston (OEM HD709-01504) is a premium aftermarket component for rock drilling and drifter rigs operating in extreme conditions. 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. As a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.

Delkom produces premium alternative rock drilling and drifter equipment and spare parts, shipped to over 100 countries worldwide. Get in touch for stock availability, bulk pricing and technical assistance.
