Pit Viper PV-275
The multi pass Pit Viper for holes up to 59.4 m (195 ft) deep and 171 mm to 270 mm (6-3/4” – 10-5/8”) diameter
The drill that put Pit Viper on the map
The PV-275 began its journey mainly in coal overburden drilling due to the 34,000 kg (75,000 lb) of pulldown it provides to a rotary tricone bit ranging from 171 mm to 270mm (6-3/4” – 10-5/8”). It has continued to not only provide coal customers sustained performance, but also hard rock applications such as copper and iron mines.
Look to the Pit Viper series of drills if technology, productivity, and high asset life for the lowest total cost of ownership are on your list of priorities.
The multi pass PV-275 Pit Viper for holes up to 59.4 m (195 ft) deep and 171 mm to 270 mm (6-3/4” – 10-5/8”) diameter, has become a staple in the mining industry through its proven performance and reliability.
The PV-275 features a patented cable feed system with automatic tensioning for improved component life and low total cost of operation
Options for both diesel and electric power plants make the PV-275 a flexible option for any type of operation.
The tower is a “live tower” design meaning it can be raised and lowered with a full carousel and the rotary head at the top of the tower – further testament to the structural design of the tower.
The optional Epiroc patented hydraulic wet clutch removes the load of the compressor during non-drilling functions and decreases fuel consumption and TCO
The standard Rig Control System (RCS) provides on board automation capability as part of the standard drill package to help deliver safety and productivity. With RCS you can run automation with an operator on board with options like auto drill and auto level or you can run with the operator off the drill with the optional BenchREMOTE package allowing one operator to run one or multiple units. With the RCS system on Pit Vipers you can even achieve your ambition of fully autonomous drilling with almost no human interaction with the drill.

Extra Capacity
The Pit Viper 275 can now be configured with the XC package (eXtra Capacity) to provide 85,000 lb (42.5 tons) bit load capacity. Along with our proven list of options, the perfect PV-275XC can be configured for your specific application. The PV-275XC takes the industry-leading Pit Viper 275 to another level of productivity and reliability, ultimately contributing to the lowest total cost of ownership in the blast hole drilling industry in its class.
Epiroc’s PV-275XC delivers a hole diameter range up to 12 ¼ inches (311mm) in both the multi pass and single pass offering which provides a clean hole of 55 ft (16.8m) and 59 ft (18m).
RCS 5 provides a foundation to add new functionality and options later without a major rebuild of the machine. Autonomous drilling can be implemented with almost no human interaction with the drill.
