Rotary Drills Features

CAT ROTARY DRILL FEATURES

Solid FrameHeavy-duty structural tubing and box section frames

provide exceptional durability.

Sturdy MastAvailable in multiple lengths for single pass and

multi-pass application. Made of rectangular ASTM 500 Grade B steel tubing on all four main chords, and cross members, creates a torsionally strong mast structure and reduces the material fatigue. All mast structures are designed with double-cut lacing in high stress areas to prevent cracking and assure long life.

Four Jack SystemThe four jack casing structures are integrally welded

to the main frame providing additional torsional strength and overall stability. The welded jack casing structures with the location of the jacks will reduce the frame tor-sional flexing and assure longer life for frame structure.

HOBO WrenchThe Hydraulically Operated Break Out wrench is a

highly efficient breakout system that increases speed of pipe changing operations and consequently increases the productivity. It also reduces the forces which affect to the mast and rotary head during the pipe changing procedure and increase the drill mechanical availability.

NOTE: MD6640 and MD6750 does not store complete drill string in pipe racks.

NOTE: MD6750 does not have a FOPS certified cab.

Power GroupFast cycle times are achieved through top of class bit

load, rotary head horsepower, bailing air and a multi-tude of time-saving systems for maximum efficiency.

Carousel Pipe Rack OptionThe patented hammer/tricone carousel places com-

plete drill strings with either DTH/bit or tricone bit in the carousel. It provides rapid pipe changes that are safe and efficient and completely controlled from inside of operator’s cab. A hydraulic break out wrench and deck wrench assist in breaking thread connections quickly and effectively.

Ergonomic CabThe FOPS certified operator’s cab features an ergo-

nomic operator’s chair, well organized controls and tem-perature/pressure controlled environment. Walls, ceiling and floor are sound and thermally insulated keeping the noise level inside the cab less than 80 dB(A).

Dust Control SystemCreated by the stationary deck and 6.4 cm (¼") thick

nylon reinforced rubber dust curtains, the dust chamber assures high dust collection efficiency and natural dust containment, with ample space for deep hole drilling and resulting cutting pile.

Track Drills

CAT TRACK DRILL FEATURESUsed in construction, quarry, and mining applications

providing effective drilling capabilities and high uptime.

Vast Pattern CoverageMultiple pattern coverage configurations available.

Solid boom extensions improve drilling by providing up to an additional 1.5 m (5.0 ft) of pattern coverage. The optional knuckle boom, available on some models, extends reach to 5.8 m (19.25 ft) and is used in rough terrain to reach up, down and over objects.

Robust BoomThe boom features an improved weldment design, and

the square tubing is reinforced in heavily-loaded areas to provide thousands of hours of trouble-free service.

Superior Carousel Rod ChangerUnlike linear alternatives, our carousel rod changer

weighs less and holds more rods, allowing the boom extension to reach further and drill deeper while main-taining stability. The feed and carousel rod hanger can accommodate multiple lengths and diameters of drill steel. This configuration eliminates fragile electronics and sensors and replaces them with robust mechanical structures and the unique geneva drive indexing system.

Ergonomic Cab DesignMost Cat Track Drills have cabs with rollover and/or

falling object protection, excellent visibility, and respon-sive controls. Some cabs are designed for front window push-out, which offers a second exit for the operator in case of emergency. The cab is also equipped with an emergency stop for immediate shutdown.

Sturdy FrameThe Cat Track Drill main frame is a box-section design

comprised of 102 mm × 203 mm × 12.7 mm (4 in × 8 in × ½ in) rectangular steel tubing, heavily reinforced in high-stress areas.

Cat Rock DrillsLow cost of ownership and reliability are yours with

renowned Cat Rock Drills. Building on a legacy of sim-plistic 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.

Owner ServiceableCat Rock Drills are so simple that owner serviceabil-

ity is a viable alternative and cost savings.

● Other models require downtime for round trip trans-portation to a clean room environment.

● Some Cat Rock Drills maintenance can be performed with the rock drill still mounted on the feed and in your own shop.

● Accumulator assemblies may be replaced in the field.

● Troubleshooting is easy since there are half the com-ponents of other drills.

Durable DesignA 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.
