MD5090 delivers high productivity by getting more holes drilled with fewer set ups. These fast cycle times are achieved thanks to its top performing rock drill, large pattern coverage, and a power group that’s ideally sized for drilling 89 mm-127 mm (3.5 in-5.0 in) holes. A non-cab, non-enclosure version, as shown, is lightweight and service accessible.

Benefits & Features
Drill more holes with fewer set-ups thanks to a sturdy boom system that is telescopic, has a 1.52 m (5 ft) extension, and swings 40 degrees to the left and right.
For even greater flexibility in drill patterns, the MD5090 feed swings 36° L to 37° R and it also extends 0.9 m (3 ft).
A sturdy extendible boom and feed provides excellent pattern coverage and requires fewer setups. The heavy-duty boom is constructed of thick square tubing with steel plate reinforcements in key areas to add strength. The feed system resists torsion and thrust loads because it is built with diagonally braced high strength steel channels.
The MD5090 is equipped with the HPR4519 hydraulic powered percussion rock drill rated at 19 kW (25 hp) output energy with dual hydraulic variable rotation motors producing 908 N∙m (670 lbf-ft) torque.
Reliable Performer
Low cost of ownership and reliability are yours with renowned Cat Rock Drills. Building on a legacy of simplistic power, these drills have long life expectancy and are field serviceable. This combination of robust design and easy maintenance means more hours of reliable, low-cost operation. For added efficiency, the pistons are matched to the cross section of the rod so the wave form is properly matched for maximum energy transfer.
Durable Design
A simple design coupled with high strength materials yields exceptional durability.
Having only half of the components of competitive models, there are fewer internal parts to wear
There are four major housings bolted together with high strength flanges eliminating troublesome long tie rods
Long life alloy bushings
Fast response accumulators provide a smooth and efficient hydraulic oscillation
Long leakage paths of the oscillator bearings yield high volumetric efficiency
Owner Serviceable
Cat Rock Drills are so simple that owner serviceability is a viable alternative and cost savings.
Other models require downtime for round trip transportation to a clean room environment
Only their OEM service technicians can perform the maintenance and repairs
All maintenance and rebuilds can be done in your shop and some maintenance can even be done with the rock drill still mounted to the feed
Accumulator assemblies may be replaced in the field
Troubleshooting is easy since there are half the components of other drills
