drilling head

The drilling head has multiple water ports to allow removal of material.

Drilling heads come in multiple designs and depends on the rock or soil being penetrated.

A wide range of drilling heads.

Under command from ground control, the lander deployed its sample arm and pushed its drilling head about 2 metres into the nearby soil.

When not needed, the drilling head swings conveniently out of the way, thus negating the need to move the complete unit out of line.

In the same way, the X axis will be lengthen by about 100 mm to compensate the offset between the plasma torch and the drilling head.

The most notable feature of this design was its simplicity and ease of manufacturing; except for the drilling head with nozzles, it mostly used off-the-shelf parts.

Permanently "bonded" diamond grinding surface on the 3/4" main grinding head and the 1/4" grinding/drilling head.

The equipment pod was attached to a steel pipe which was lowered through the bottom of the vessel in sixty feet sections, exactly like a drilling head on an oil rig!

Using real time data direct from the drilling head, the computer models developed by MAT constantly updates and provides insight that helps guide operational decision making on a day-to-day basis.

The Tharoo themselves were in the drilling head, watching the progress of the atomic-blast, but not making phonic soundings as yet, for their destination was still nearly three-quarters of a mile beneath them.

Geosteering is an oilfield term that refers to directional drilling guidance systems that have on board sensors to determine the rock type either being drilled or in proximity to the drilling head.

Effective cutting and drilling area - The drilling head is positioned on the left side of the plasma torch therefore the Y stroke of the machine is reduced by about 300 mm.

The conical drilling head was already deeply buried in the sediment, and a few meters of the broad metal tape that was the Mole's 'payload' lay stretched out on the seabed behind it.

"We found the most serious allegations to be without merit, including the suggestion that a lack of adequate documentation created a serious safety risk," Michael Bromwich, the department's offshore drilling head, said in a statement.

Location and guidance of the drilling is an important part of the drilling operation, as the drilling head is under the ground while drilling and, in most cases, not visible from the ground surface.

There are IRAM models to take from 2 to 10 drilling heads and multispindle heads are available for those instances where the centre to centre distance is too small for adjacent single spindle heads.
