COP 1838HD Drifter

Developed as a practical replacement for intensive field operation, the COP 1838HD Drifter (OEM reference 8311 1257 50) provides a replacement option for compatible Atlas Copco drilling applications. In the assembly, it provides the core percussion and drilling action required to transfer impact energy and rotation to the drill string. It is cross-referenced for equipment including BOOMER L2D and COP 1838HD.

Its design focuses on high-frequency impact, hydraulic pressure, rotation, vibration and continuous rock-drilling duty. The use of precision-engineered internal interfaces and heavy-duty construction suited to demanding drifter operation supports consistent fit at the relevant interfaces and reliable operation after replacement. In practical maintenance terms, this supports consistent drilling performance, efficient energy transfer and reliable operation in production and development drilling.
