When drilling deep holes in rock for quarrying, construction, or excavation work, the Ingersoll Rand JH40C1 Reversible Pawl Jackhammer delivers 2,000 BPM through a 2.63" stroke and 2.5" bore. This longer-stroke configuration concentrates pneumatic impact energy at the drill steel, while the 7/8" x 3-1/4" hex shank accepts matching jack rods and carbide-tipped drill steels. An easy-access adjustable three-speed throttle gives the operator control over drilling speed as material and hole conditions change.
The JH40C1 supports wet or dry drilling and is rated for holes up to 2" in diameter and 18 ft deep. Reversible pawls allow the drill steel to rotate in the opposite direction when needed, helping manage the steel during drilling and withdrawal. An integral muffler reduces exhaust noise at the tool, while the 22.5" body and 61 lb operating weight place this model in a substantial pneumatic drilling class for jobs that require deeper reach than lighter rock drills. Catalog performance figures are measured at 90 PSI air pressure.

Features:
- Easy-access adjustable three-speed throttle provides control over drilling action as working conditions change.
- Reversible pawls permit directional rotation for managing drill steel movement during drilling and removal.
- Supports both wet and dry drilling methods to suit the jobsite setup and material being drilled.
- 2.63-inch piston stroke and 2.5-inch bore produce the impact action required for deep rock-drilling work.
- 2,000 blows per minute maintains steady percussion through compatible jack rods and drill steels.
- Integral muffler helps reduce exhaust noise generated at the tool.
- 7/8-inch x 3-1/4-inch hex shank configuration matches compatible Ingersoll Rand steels, bits, and retainers.
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 blast, splitting, and utility holes in rock formations.
- Construction and excavation — creating holes for anchoring, foundation work, and site preparation.
- Mining support work — drilling rock where compressed-air equipment is used underground or at the surface.
- Road and infrastructure projects — penetrating rock encountered during trenching, grading, and civil construction.
- Contract drilling crews — completing wet or dry holes up to the tool’s specified diameter and depth limits.
FAQs:
- Q: What size drill steel fits the Ingersoll Rand JH40C1?
A: The JH40C1 accepts tooling with a 7/8" x 3-1/4" hex shank. Confirm the shank size and accessory type before ordering replacement jack rods, bits, or retainers. - Q: How large and deep can the JH40C1 drill?
A: Ingersoll Rand lists a maximum hole diameter of 2 inches and a maximum hole depth of 18 feet. Actual results depend on rock conditions, bit selection, air supply, and drilling technique. - Q: How much compressed air does this jackhammer require?
A: Catalog air consumption is 115 CFM at 90 PSI. The compressor and distribution system must maintain the required pressure and airflow while the tool is operating. - Q: What does a reversible pawl do?
A: The pawl mechanism controls drill-steel rotation, and the reversible configuration permits rotation in either direction. This can help the operator manage the steel during drilling or withdrawal. - Q: Can the JH40C1 be used for wet drilling?
A: Yes. The manufacturer identifies this jackhammer and rock-drill family for wet or dry drilling.
