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. 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. 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. 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. Pneumatic Air Rock Drill by Sullair.
