Exit-Side Solution for the Horizontal Drilling Industry

The TONGHAND® by LaValley Industries is a powerful tool designed for the HDD industry's exit-side operations. With this device, a single operator can precisely torque and un-torque drill rods while sitting comfortably and safely in the excavator cab. By doing so, TONGHAND® eliminates the need for physically demanding wrenches and removes the risks associated with personnel working in hazardous areas.

TONGHAND® is compatible with any excavator brand and can be efficiently powered by the machine's auxiliary hydraulics. The tool's telescoping roller arms can lift, tilt, shift, rotate and position a single rod or drill string securely and accurately under the operator's full control.


Thanks to its patented TongVise™ technology, the TONGHAND® can quickly and precisely make and break joints, regardless of whether you're working with drill rods, subs, reamers or other tooling. By saving time and money and enhancing job-site safety, the TONGHAND® is an invaluable asset to any HDD operation.
