The new Cat MD5075C replaces the MD5075 and is capable of drilling holes of 76-114.3mm in diameter to a depth of 31m. The 224kW C9 engine can be configured to meet emissions standards worldwide. The compressor, which features widely variable air control, produces 9.9m3/min at 10.2bar.

Two different rock drill choices enable matching to the application to achieve the highest production rate. The standard rock drill on the MD5075C is the HPR5123, which uses 45mm or 51mm drill rod. Also available is the HPR4519 rock drill, which uses 45mm drill rod. Caterpillar claimed that it is the only manufacturer offering rock drills designed to be serviced on-site - for reduced downtime and costs - and its rock drills can deliver three times the lifespan and less than one half the parts cost of competitive rock drills.

Caterpillar stated that Cat rock drills deliver three times the lifespan of competitive drills, and the Cat carousel rod changer and drill rod-handling system are a reliable mechanical design with no sensitive electronic sensors to cause downtime. The Cat C9 engine and Cat 315E excavator undercarriage can further enhance productivity and reliability.

The MD5075C also incorporates technology to assist in operations and equipment management. To support the operator, Drill Assist monitors main hydraulic systems and automatically adjusts to pre-programmed parameters. It incorporates anti-jam, anti-plunge and anti-plug, which can boost productivity and increase the life of the drill string.
