Reg Piston

The Reg Piston (OEM 3217 9203 12) 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. 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.
