Ingersoll Rand JRD30-B Reversible Pawl Air Rock Drill | 7/8″ x 4-1/4″ Shank Size | 2700 BPM | 1.44″ Stroke | 2.38″ Bore

Description

Built for quarry work, utility installation, road construction, and general concrete drilling, the Ingersoll Rand JRD30-B Reversible Pawl Air Rock Drill combines a 2.38″ bore, 1.44″ stroke, and 2,700 blows per minute (BPM) to deliver rapid drilling performance in concrete and soft to medium rock. Its reversible pawl mechanism allows the drill to reverse rotation, making it easier to free a jammed drill steel without unnecessary downtime. This practical feature helps crews maintain productivity while reducing the effort required to remove stuck bits in demanding field conditions. 7/8″ x 4-1/4″ hex shank provides compatibility with longer drill steels while maintaining a secure connection during drilling. Suitable for both wet and dry drilling applications, the JRD30-B can produce holes up to 1.5 inches in diameter and 10 feet deep when used with the appropriate accessories, making it a dependable choice for contractors, utility crews, mining operations, and industrial construction professionals.
