MRD-40 Rock Drill

Single-throttle lever controls all tool functions: automatic-off, blow only, and progressive drill speeds.

We eliminated many high wear parts. To you this means less loss of power due to wear, less downtime to replace worn parts, and lower overall maintenance costs.

With only two parts moving during operation, a non-corrosive automatic valve, less radial piston movement and high-tech alloys, our drills do not require special rock drill oil. Under normal operating conditions, oil carry-over from the compressor combined with moisture in the air will provide sufficient lubrication.

 

Models vary by region. Please contact your Sullair sales representative for more details.
