Drilling with the Comacchio MC450P Rotary Drilling Rig..

The MC450P is one of the worlds most powerful, compact drilling rigs..

The MC450P is transported to site with our in house DAF CF 75 26t beavertail plant truck, this truck also carries all in hole equipment as well as auxiliary equipment such as compressors and mud recycling equipment - allowing us to keep our overheads low and pass the savings on to you, the client.

With a rotary head capable of low speed, high torque; as well as high speed with less torque, the Comacchio MC450P is a formidable force capable of progressing boreholes in any geology to depths in excess of 250m using either DTH Hammer, rock roller, drag or PCD bits.

Other systems include ROBIT casing and wireline coring.

Flushing mediums include mud/water recirculation via the on board pump, or air flush via an auxiliary compressor.

Rig Dimensions (when working)

Width: 2.00m Length: 5.00m Height: 7.50m Weight: 9.00 tonne

Rig Feed: 4.5 tonne Rig Pull Back: 6.50 tonne Engine Power: 115hp

Hollow/Solid Stem Auguring (Fully guarded)

The rotary drive heads on our rigs can be set to a low speed high torque setting to allow for both hollow and solid stem auguring in 6", 8", 10" & 12" diameters to depths of 30m+.

Open Hole Drilling - Drag Bits / Rock Rollers /Claw Bits / PCD Bits / DTH Hammers (Fully guarded) 

Down the hole hammer (DTHH), tri-cone rock roller, drag and PDC bits can be used for rotary open hole drilling.  

DTHH is used with air flush for open hole drilling in rock and hard strata. Tri-cone, drag and PCD bits can be operated with air or water flush.  

Open boreholes can be formed to depths of 250m+. 

Conventional Rotary Coring & Wireline (Fully guarded) 

Thin wall double tube core barrels incorporating a plastic liner are used to retrieve cores up to 116mm diameter.  

The rigs can use water or air flush as required.  

The ability of our rigs to soil sample and rotary core allows for borehole progression in most ground conditions to depths of 250m+.

SPT/DPT/Undisturbed Sampling (All SPT hammers calibrated to give N60 values)

SPT, DPT and undisturbed sampling (100mm diameter U100 & 70mm diameter U70) can be carried out during the drilling of boreholes.

Flushing Mediums 

Air Flush - Use of “stuffing box” to allow for a clean site

Water/Mud Flush - Use of drilling fluid recycling systems

Common Applications for the MC450P Rig
