Part No. 3115 2129 00 is an impact piston used in Atlas Copco COP 1838HD+ rock drill.
It is one of the core components of the rock drill, responsible for generating high-frequency impact energy and transferring it to the shank adapter, which drives the drill steel to break rock.
The piston works under high pressure and high impact frequency, so material quality and machining accuracy are critical. Our product is manufactured according to OEM standards and can directly replace the original part.
