Overview
Completely CAT®. Completely Productive
The CAT® MD6250 is completely manufactured with Cat parts to allow you to exploit the full potential of the machine. With integrated autonomous features and the ability to incorporate Cat MineStar™ technologies, the MD6250 offers precise and reliable performance in many drilling applications. An easy-to-own and operate machine, with increased ease of maintenance, offering the reliable performance you can expect from Caterpillar and benefiting from the world-class support of our Cat dealer network. Designed to drill holes from 152 to 250 mm (6 to 9.8 in) in diameter, the MD6250 is optimized for single or multi-pass drilling, for both rotary and down-the-hole hammer drilling modes.

A State-of-the-Art Driving Position
Ergonomic controls allowing the driver to stay alert and avoid fatigue Controls through multifunction manipulator and easy-to-use and intuitive touch screens Incredible visibility, achieved through numerous cameras and panoramic windows A heated and ventilated seat for greater driver comfort
100% Cat Integration
Fully Cat, with parts, components, and design features common to all Cat drill models Shared software for autonomous features Benefiting from world-class support from the Cat dealer network
The Cat Electronics: The Backbone of the Machine
A common electronic architecture within all Cat machines to ensure technician control The ET Cat electronic device allows for quick and simple troubleshooting Serves as a common platform for integrating future autonomy solutions Product Link™ Elite provides real-time performance monitoring
Adjusted Powertrain Group
The volumetric air flow control allows the driver to reduce the air flow by up to 50% to adapt to specific drilling tools and applications. A C27 engine adapted to the largest compressor in this category, in order to achieve fast cycle times. An optimized powertrain to withstand difficult drilling applications. High and low pressure configurations allow for variable air volume control. Optimal feed force, rotational torque, and air intake reduce fuel consumption.
Technology And Automation
Drill Assist functionality, incorporating automatic leveling, automatic jacks, automatic raising and lowering of the mast, and automatic drilling. Monitoring the health and performance of the machine allows for productivity optimization. Drilling depth counter reduces excessive or insufficient drilling. Ready to connect to the Cat MineStar technology suite, such as Terrain for drilling and Command for drilling.
Easy Maintenance
Large water and fuel tanks reduce filling time Grouped access points for maintenance and clear paths for hoses and cables reduce maintenance duration Cat MineStar Health offers onboard monitoring of machine performance and health Extended maintenance intervals reduce downtime for maintenance
Durability
Designed to consume less fuel, which reduces engine emissions Tier 4 Final compliant engines reduce NOx and particle emissions Reduced waste production and operating costs due to greater system and component interchangeability and a reduction in unique part numbers Extended maintenance intervals reduce the amount of waste released into the environment
