For quarry, excavation, mining, and construction crews drilling into rock, the Ingersoll Rand JRD50-C Reversible Pawl Air Rock Drill delivers 2,300 blows per minute through a 2" stroke and 3" bore. This percussion output supports holes up to 2" in diameter and 16 ft deep, while the 1" x 4-1/4" hex shank accepts drill steel made for that specific shank and collar configuration.
The JRD50-C includes an easy-access adjustable three-speed throttle for changing tool output as drilling conditions vary. Reversible pawls manage drill-steel rotation, an integral muffler helps reduce exhaust noise at the tool, and wet-or-dry drilling capability allows crews to match the drilling method to the jobsite. The drill consumes 120 CFM at 90 PSI, so the compressor and air-distribution system must sustain the specified flow and pressure during operation.

Tech Tip: To increase tool performance, extend tool life and lessen repair costs use it with a Filter-Regulator-Lubricator (FRLs)
Applications:
- Quarry and aggregate operations — drilling production, splitting, and utility holes in rock.
- Construction and excavation — penetrating rock during foundation, trenching, grading, and site-preparation work.
- Mining support — completing pneumatic drilling tasks in surface or underground operations.
- Road and infrastructure projects — drilling for anchors, blasting preparation, and controlled rock removal.
- Contract drilling crews — producing wet or dry holes within the tool’s specified diameter and depth limits.
FAQs:
- Q: What shank size does the Ingersoll Rand JRD50-C use?
A: The JRD50-C uses a 1" x 4-1/4" hex shank. Drill steel and related tooling must match both the shank diameter and collar length. - Q: How does the JRD50-C differ from the JRD50-A and JRD50-B?
A: The catalog-listed difference is the shank configuration. The JRD50-C uses a 1" x 4-1/4" shank, while the JRD50-A and JRD50-B use 7/8-inch shanks; their remaining listed performance specifications are the same. - Q: What air supply does the JRD50-C require?
A: Ingersoll Rand lists air consumption at 120 CFM, with performance figures measured at 90 PSI. The compressor, couplings, and supply line must maintain that airflow and pressure while the drill is operating. - Q: What is the maximum drilling capacity?
A: The catalog lists a maximum hole diameter of 2 inches and a maximum hole depth of 16 feet. Actual results can vary with the rock, bit selection, drill steel, air delivery, and operating technique. - Q: Can the JRD50-C be used for wet drilling?
A: Yes. Ingersoll Rand specifies the JRD50-C for wet or dry drilling.
