Overview

Cat® from the ground up, productive from the ground down

The Cat® MD6250 rotary drill is built from the ground up with 100 percent Cat parts to help you get the most out of your operation. With built-in autonomous features and the option to integrate Cat MineStar technologies, the MD6250 offers accurate, reliable performance in any hard rock drilling application.

Benefits

The Backbone of the Machine Cat Electronics

The MD6250 is controlled through proven Cat electronics, with an electronic architecture your technicians are familiar with from other Cat machines. Integrated machine protection features and interlocks help keep your operators safe, and the machine up and running by preventing potential failures or misuse.

With Cat Electronic Technician (Cat ET), troubleshooting is quick and easy. The MD6250’s electronics also provide a common platform for the integration of a number of future autonomy solutions.

To Improve Operational Performance Technology & Automation

Technology and automation is foundational in MD6250 to enhance operational performance. MD6250 delivers drill assist functions, semi-autonomous / autonomous features and machine health reporting, all of which improve drilling efficiencies and results.

For System Efficiencies Matched Power Train

The MD6250 matched powertrain delivers performance and fuel consumption benefits thru electronic control strategies. Variable volume air control allows drillers to match compressor output to specific application and drill tooling.

The MD6250 powertrain is optimized with a high powered engine and largest “standard” compressor in class for fast cycle times and its designed to withstand the rigors of drilling applications.
