UnderWunder Underground Boring Machines

 

  • BORING MACHINE - Weighing in at 96lbs., this machine is specifically designed to bore horizontally from ground level without the need of a working pit.  It's functional and efficient at getting the job done.  It's weight and size make it a perfect fit for the back of a work truck.  Available with Honda or Briggs & Stratton engines.  (2006 model shown here with Honda 5.5hp engine)
  • BITS & REAMERS - from our 2" bit to our 6" reamer all come with staggered carbide tips to handle the roughest soil conditions.  Staggered carbide tips creates an unequal serrated cutting action.  Our line of bits and reamers will allow you to bore up 6 inches in diameter.
  • DRILL STEM - All of our drill stem is made out of 1" O.D. Schedule 80 drill tubing.  Available in standard sizes: 20', 12', 10' and 9'.  You choose what size best fits your transportation and job site needs.  Custom sizes are available anytime. 
  • SIGHT & ALIGNMENT/SAFETY PACKAGE - This is simple to use and will enable you to hit a 4" target 9 times out of 10 when boring under a two car garage.  
  • ACCESSORIES - Our accessories are designed to fit all of our boring machine models.  We keep all parts in stock.  Call us to find out how we can help get your machine back into top performance.

Under Wunder Corporate Mission

Our mission is to provide a quality piece of equipment at an affordable price.  We have since set the standard for durability and function since 1970. 

All of our products have been designed by a seasoned irrigation professional.  We do not offer silly gadgets or pre-packaged concepts only what you need when you need it.  We are proud to state the vast majority of the components compromising our line are manufactured in-house.

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 nd 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.

All of our products are offered individually with no minimum order requirements.  In most instances, products are shipped within 24hours.  We constantly monitor shipping costs in order to maintain competitive pricing and timely transit times. 
PERFECT BORES ALWAYS!
By utilizing our machine on job sites you will be able to offer your customers a way to keep their existing structures (shrubs, trees, sidewalks, roads, etc.) looking perfect!  no more wasted time cutting concrete and unsightly concrete patches.  Complete bores in minutes rather than hours and leave the job site looking as if you were never there.

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 bores 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.


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.
