A New Geotechnical Drill Rig with Muscle

I’ve got a new product to announce for our friends in geotechnical drilling: the GT8 rig from Versadrill. We recently got to try out this new hydraulic, geotechnical drill rig on our premises and shot a video so we could give you all a first-hand view of what it looks like, how it operates and what it can do.


The GT8 is a sturdy yet incredibly powerful multifunctional rig for geotechnical drilling. To give you an idea, here are some stats. It has a maximum rotation speed of 975 RPM, and maximum torque of 8,270 ft-lbs. The speed at maximum torque is 55 RPM and the torque at maximum rotation speed is 480 ft-lbs, providing drillers with a pretty amazing combo. The GT8 allows you to get great depth – up to 600 meters NWL.


It measures 20 feet in length by 7 feet, 5 inches in width by 9 feet, 2 inched in height and weighs only 18,000 pounds and is completely hydraulic. The GT8 also offers some cool options, like remote control, tiltable mast with degrees from -90 to -45 degrees, and adjustable mast dump. The Gt8 is the only geotechnical drill rig that offers a standard diamond drill chuck and rotation capable of handling rods from A to P with a maximum rotation speed of 975 RPM.  What’s more, this chuck can be easily converted to a top drive style to accommodate any standard tooling common in the geotechnical industry. For the times geotechnical drillers need to perform core sampling, this rig is super capable and an excellent choice.


There are a whole bunch of other great capabilities and functions that I won’t get into here, but if you are interested, I encourage you to contact us so we can give you more details.
