Cop1838+ Rock Drill Impact Piston 3115212900 Spare Part for Epiroc 3115 2129 00
Precision impact piston 3115212900 for the Epiroc COP1838+ hydraulic rock drill drifter. Manufactured from high-strength hardened alloy steel with CNC machining, heat treatment and precision grinding, this percussion piston delivers powerful, reliable impact energy for efficient rock drilling in demanding mining and tunneling applications.
Product Overview
The 3115212900 Impact Piston is the core percussion component of the Epiroc COP1838+ hydraulic rock drill drifter. Driven by high-pressure hydraulic oil, it reciprocates at high speed inside the drifter, striking the shank adapter to convert hydraulic energy into percussive impact energy for breaking rock. Manufactured from high-strength hardened alloy steel with CNC machining, heat treatment and precision grinding, this piston delivers exact OEM dimensions, superior fatigue resistance and long service life under continuous heavy-load drilling in harsh underground and surface conditions.
