30 lb Air Rock Drill for Concrete

The Ingersoll/Rand JRD30-B is a 30 lb class pneumatic rock drill built for concrete work. It delivers 2700 blows per minute at 73 cfm air consumption. The 7/8 in x 4 1/4 in hex shank fits standard drilling steel. This tool suits contractors driving holes up to 10 ft deep and 1 1/2 in diameter.

Sustained Load Behaviour

Continuous operation at 2700 bpm demands a steady 73 cfm supply to keep the 2 3/8 in bore piston cycling without pressure drop. The sound reducing muffler lowers exhaust noise during long shifts. No vibration reducing handles are fitted so operator fatigue increases with extended use. Adequate compressor capacity prevents stalling in hard aggregate.

Installation and Common Issues

Connect the male 3/4 in NPT air inlet to a lubricated line rated for the required flow. The latch retainer secures steel quickly but must be checked for wear to avoid tool slippage. Insufficient air volume causes low blow energy and overheating. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How much air does the 73 cfm drill consume during extended use?

The drill draws 73 cfm of compressed air at full load, so the compressor must sustain that flow continuously.

What compressor fitting and hose size does the 3/4 in NPT male inlet require?

The tool has a 3/4 in male NPT air inlet; you need a matching female NPT coupler and a hose rated for 73 cfm flow.

Will the 7/8 in x 4 1/4 in hex shank fit the steel I already use?

The shank accepts 7/8 in x 4 1/4 in hex steel; your existing drill steel must match that exact shank size to work.
