For quarry drilling, excavation, and construction work that requires a larger tooling interface, the Ingersoll Rand JH40C3 Reversible Pawl Jackhammer uses a 1" x 4-1/4" hex shank for matching jack rods and drill steels. Its 2,000 BPM percussion rate, 2.63" piston stroke, and 2.5" bore deliver the repeated impact action needed to penetrate rock and similarly hard material. The tool supports wet or dry drilling, allowing crews to match the drilling method to the jobsite and dust-control requirements.
The JH40C3 is rated for holes up to 2" in diameter and 18 ft deep. An easy-access adjustable three-speed throttle provides selectable control as drilling conditions change, while reversible pawls manage drill-steel rotation during operation. The integral muffler helps reduce exhaust noise at the tool. With an air requirement of 115 CFM at 90 PSI, this jackhammer must be supplied by a compressor and air-distribution system capable of maintaining the specified pressure and airflow under load.

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 holes in rock for extraction, splitting, and site development.
- Mining work — supporting surface and underground drilling where pneumatic equipment is specified.
- Construction and excavation — penetrating rock encountered during foundation, trenching, and grading projects.
- Road and infrastructure work — drilling for anchoring, blasting preparation, and rock removal.
- Contract drilling crews — completing wet or dry holes within the tool’s specified diameter and depth limits.
FAQs:
- Q: What shank size does the Ingersoll Rand JH40C3 use?
A: The JH40C3 uses a 1" x 4-1/4" hex shank. Compatible drill steels and jack rods must match this exact shank configuration. - Q: How does the JH40C3 differ from the JH40C1 and JH40C2?
A: The catalog-listed difference is the hex shank size. The JH40C3 uses a 1" x 4-1/4" shank, while the JH40C1 and JH40C2 use 7/8-inch shanks with different collar lengths. - Q: What air supply does the JH40C3 require?
A: Ingersoll Rand lists air consumption at 115 CFM, with performance figures measured at 90 PSI. The compressor, fittings, and air line must sustain that flow and pressure while the tool is running. - Q: What is the maximum drilling capacity?
A: The manufacturer lists a maximum hole diameter of 2 inches and a maximum hole depth of 18 feet. Actual drilling results will also depend on the rock, bit selection, air delivery, and operating technique. - Q: Can this jackhammer be used for wet drilling?
A: Yes. The JH40C3 is specified for wet or dry drilling.
