WesTrac introduces the Cat MD6250 and MD6310 rotary blasthole drills to the Australian market

WesTrac is providing Australian mining operators with unprecedented levels of power and control through the introduction of the most advanced Cat rotary blasthole drills ever.

Ideally suited for Australian mining conditions, the Cat MD6250 provides operators with a sophisticated option for drilling medium blastholes up to 250mm, while the Cat MD6310 is suitable for larger holes up to up to 310mm. The duo will be joined in 2019 by the Cat MD6200, designed for creating smaller blastholes up to 200mm.

“We believe these drills are some of the most advanced in the market with the electronic control strategies offering operators high levels of fuel efficiency and power,” says WesTrac WA Chief Executive Jarvas Croome. “They are both fully Cat-designed and assembled from Cat parts, meaning that operators can be confident of their strength and reliability.”

WesTrac NSW and ACT Chief Executive Greg Graham adds, “As well as offering advanced Cat technology as standard, both of these drills are also fully autonomous-ready, meaning operators can choose a level of automation that suits them. They are suitable for all types of open-cut mining, quarrying and heavy construction applications.”

With a powerful Cat C27 ACERT Engine, the MD6250 is ideal for single-pass 10 to 12m rock benches and can drill holes from 152 to 250mm in diameter. It is suitable for both single and multi-pass applications in rotary and down-the-hole modes. With its 11.2m mast attached it can achieve multi-pass hole depths of 53.6m, while the 13.7m mast can achieve depths of up to 37.9m.

The MD6250 can apply bit loads of 22,321 kg and 32,655 kg (72,000 lbf) respectively for the 11.2m and 13.7m masts and is suitable for angle drilling from 0 to 30 degrees in 5-degree increments.

The MD6310, meanwhile, comes with a Cat C32 ACERT Engine and is application built for 12 to 15m bench heights and for hole diameters up to 311mm. The drill is also suitable for both single and multi-pass applications in rotary and down-the-hole modes. With its 13.7m mast attached it can achieve multi-pass hole depths of 62.5m, while the 17.5m mast can achieve depths of up to 48m.

The MD6310 can apply bit loads of 31,640 kg and 42,149 kg (92,922 lbf) respectively for the 13.7m and 17.5m masts and is capable of drilling 30-degree holes for cast blasting.

Both drills feature advanced Cat technology that improves drilling efficiency and reduces fuel use. Unlike other drills that run constantly at high load, the new Cat drills feature variable air volume that provides up to 50 percent less engine load, reducing costs.

“Because the MD6250 and MD6310 also both feature Cat Product Link™ Elite they are able to generate and send relevant statistics on machine health, location and production,” says Jarvas Croome. “This data is sent back to the office in real time and allows for timely analysis, increased productivity and greater uptime.”

Safety is a huge consideration for the MD6250 and MD6310 which both come with world-class cabs featuring large windows for greater operator visibility, drill depth indicator, and virtual head stops and interlocks, protecting the machine and the operator.

“The auto drill assist feature automates part of the drilling cycle – something that has the potential to improve accuracy and efficiency, and to drive down operating costs,” says Greg Graham. “Remote control or semi-autonomous drilling can also be achieved through the use of Cat MineStar™ options.”

The Cat Terrain for Drilling feature uses satellite guidance to increase pattern accuracy by up to four times, while Cat Command automates the drilling cycle, allowing a single operator to manage multiple machines at the same time.

WesTrac is already supplying customers with MD6250s and MD6310s and has a number of the drills on pre-order to ensure good availability and timely delivery. New variants will be arriving throughout early-mid 2019, with the first MD6200s scheduled to arrive in the country in mid-2019.


Cat MineStar™ technologies help businesses make informed and confident decisions by turning data into insightful information they can use to get more out of their mines. The technology assists with everyday challenges from controlling costs to extending equipment life and enhancing safety. Cat MineStar™ can fit into all operators – working with any brand of equipment and sharing data across existing machines, systems and technologies. Customers have the option of selecting one capability to address a need like accident avoidance or maintenance tracking, or combine several into a comprehensive solution.


Cat Product Link™ redefines fleet management effectiveness. Its easy-to-use interface, called VisionLink™, enables customised health and utilisation reports, and mapping and mixed fleet capabilities. Product Link™ transmits the information via cell and satellite, and connects customers to the Caterpillar dealer network. Product Link™ provides accurate, timely and useful information about the location, utilisation and condition of equipment—the kind of information that can make a huge difference in the efficiency and costs of entire operations.
