Piston

The Piston (OEM 345 702 38) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. 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. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.

Delkom manufactures and exports premium alternative rock drilling, drifter equipment and spare parts to more than 100 countries. Contact us for current availability, bulk pricing and technical support.
