Specifications

The SULLAIR MRD-9 Rock Drill is a light-weight pneumatic rock drill that provides fast, economical means for drilling 1/2 in to 1 in diameter holes up to 8 in deep. At half the weight and air consumption of most pneumatic rock drills, the SULLAIR is ideal for high volumes of drilling small to medium diameter holes in hard stone.

Features
Dead Man Safety Handle
The Sullair drills are designed so that the tool automatically stops operating when the operator releases the throttle lever.

One Control for Drilling and Blowing
The single throttle lever controls all tool functions from off, to blowing only, to progressive drilling speeds.

Variable Throttle Control
Allows stepless speed control for maximum drilling production.

Continuous Hole Cleaning
Blowing air is directed through the drill rod at all drilling speeds to clear debris from the hole.

Direct Rotation of the Piston
This feature reduces torque loss and eliminates wearing parts, such as the rifle bar assembly.

Less Maintenance
The unique design of the Sullair drills eliminates many high wear parts. This means less loss of power due to wear, less downtime to replace worn parts and lower overall maintenance costs.

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

Oil Reservoir
A built-in oil reservoir assures direct lubrication to rotating parts. Use of standard 90-140 weight gear lubricant extends the life of critical parts.
