Percussion Piston

The Percussion Piston (OEM 3363 0862 79) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. As the core driver of percussive energy, it converts hydraulic pressure into the high-impact blows that fracture rock, making its dimensional accuracy and surface integrity critical to drilling efficiency.

Manufactured from premium hardened steel with precision-ground striking and guide surfaces, it withstands extreme cyclic impact loads while maintaining tight running clearances for maximum impact energy transfer. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
