Pusher Leg Pneumatic Rock Drill

DESCRIPTION:

Atlas Copco water flushed, pusher leg mounted rock drills are designed for driving drifts and tunnels with a small cross section. These well-proven rock drills are recognized for their high performance and reliability. They are intended for use for hole diameter range of 27 to 41 mm with H22 rotation chuck as a standard.

When used with Atlas Copco tapered button bits, penetration rate will improve some 25-50% compared to conventional integral steels and have three to five times longer service life.

All-round rock drill which suits most drilling applications. It has a robust rifle bar rotation with large sliding surfaces, which has contributed to its reputation as a durable dependable drill. It is easy handled in collaring due to the location of the single air inlet, located at the same side as the main control. Also the pusher leg control is located at the back head of the rock drill.
