UnderWunder Underground Boring Machines

TECHNICAL
Our machines weigh in at 96lbs. and are specifically designed to be transported without the use of a trailer.  Our bits are three-bladed and have leading carbide tipped edges arranged in a serrated pattern.  Water is used to keep the bits cool and to create slurry.  Our drill stem is manufactured from 1" O.D. extra heavy domestic steel pipe and come in sizes so that a pipe rack is not needed.

Our selection of carbide bits and reamers remove only the amount of soil yo need, leaving the soil under the existing structure intact.  Our bits will cut through most rock, tree roots, and soil conditions.

 Allow our machine to do the work for you.  it is winch driven and does not require the operator to use brute force.  No more expending energy by hammer, drive, or force trying to lay pipe underground.  Remove the burden of boring from the operator and place it on the machine.

•  Why does your machine use the 5.5hp engine?
• With almost 40 years of experience, it has been proven the use of the 5.5hp engine is enough power to safely get the job done.
• Your bits have multiple pieces of carbide rather than one large piece, why?
• Carbide is a very hard substance but it can and will shatter.  Our experience has shown us that using multiple pieces of carbide and strategically staggering them over the surface of the bits will work like a serrated knife to chip and cut through rock and tough conditions thus limiting damage to the carbide itself.
• Why do you recommend the 4 piece "Sight and Alignment Package?"
• This accessory helps to keep the drill stem on target while keeping the operator away from all rotating pieces.  
• How far can I bore with your machine?
• We have found the majority of Horizontal boring completed with our machine are usually not over 50'.  Operators of our machine often comment boring over 100'.  
• What can I bore?
• Our machine will easily bore through dirt, soil, clay, roots, sandstone, and most types of rock.  
• What is the winch for?
• The winch provides over 300lbs of forward pressure.  At 96lbs a drive-train would not work the  way directional drilling machines do.
• Why not use a clutch?
• Our machine is designed to be efficient not overpowered.  At 5.5hp and 96lbs there is no need for a clutch to prevent rollover thus there is no need to have tracks like tunnel boring machines.
