    Small Boring System Handles
   Big Jobs Accurately & Quickly

The simplest solution is usually the best one, and that adage is exemplified by a lawnmower-size device that bores holes as big as 15 inches in diameter under roads and highways.  The device, called the Maxibore, has received industry awards based on the benefits it brings to the process of underground facility placement.

The machineuses a 5 – or 9hp motor to drive a drill stem at 600 rpm.  A small stream of water goes through the stem to cool the bit and flush out the cuttings.  Different bits allow drilling through virtually any rock or soil. The Maxi-BORE can be purchased for less than $5,000 …

According to Tena Bradley,  the machine’s most highly prized feature is it’s accuracy.  She explains that a special drill stem guide controls the depth and angle of the bore. Direction is controlled by a aiming sight that can be aimed at a target stake up to 200 feet away.

When the boring is underway, forward speed is controlled by a hand winch mounted on the machine.  “The operator can feel impulses from the drill bit that are transmitted up the drill stem,”  Bradley said.  “From this feel, the operator knows when to slow down or change the bit.  But, if the propulsion were mechanized, the drill would be automatically forced forward and be deflected off of rocks or other obstructions.”

The 600-rpm speed of the drill rotation is also a factor in accuracy, according to Bradley. “Any physics teacher will tell you that the faster you spin an object, the more it wants to stay in it’s original path …


it’s a principal called ‘conservation of angular momentum’.”   Bradley added, “The unit is so accurate that some of our customers use it for sewer placement.  You can maintain the exact grade needed for drainage flow.”

Because of the low cost of the unit, it is proving extremely popular with public works departments in smaller communities with very limited budgets. Officials of the city of Roanoke, TX. Reported they were able to save nearly $50,000 on a water project.  In nearby Farmers Branch, the public works people reportedly drilled through 44 feet of “solid white rock” in less than 90 minutes.

An Oklahoma contractor reported he has been using a Maxi-BORE to install telephone cables and gas pipelines.  “Overall, it’s been a good machine,” he said.  “It works better in some terrains than others, but it does go through rock real well.”

Art Harbolt, tool manager for Henderson Electric Company of Louisville, KY, said his first experience with the unit was during a highway project.  His company was already behind schedule and was paying penalties when they experienced problems getting pipe under the highway. As the crew waited, one manufacturer demonstrated his boring system and promptly lost $28,000 worth of equipment beneath the roadbed.  “The state wouldn’t let him dig into the road to retrieve it either,” Harbolt said.

Next, Harbolt tried the Maxi-BORE.  “We went through hard rock, pulled the pipe under that highway, cleaned up and were back at the shop in less than four hours,” he said.  “I just love the thing - As a tool manager, when I find something that works this well, I get really excited about it.”

The City Council of Vidor, Texas approved purchase of Rota-Jetter Culvert Cleaning Machine!   Steve Coleman, Street and drainage Manager was impressed with the amount of tree roots removed from the very first culvert cleaned with the systems.   Steve states there culverts are totally full of Pine tree needles, branches and dirt from the major storm last year.   The general plan is to keep the Rota-JETTER Culvert Cleaning Machine on the streets of Vidor every workday.  All the culverts have to be initially cleaned to get water runoff moving.   One Texas County went from 5 to 6 culverts cleaned a day with road crews and after purchase of their own Rota-Jetter Culvert Cleaning Machine they were able to clean over 21 Culverts in one day…


Culvert Cleaning Ideas: Texas County purchased the Rota-JETTER Culvert Cleaning Machine.  The company recommends two employees to operate the Machine.   Liberty County, Texas has figure out how to run machine and get more productivity with just one employee!  Sort of!   Liberty County employee goes by the local Minimum Security Prison, near town and picks up four labors.    The single County employee instructs and supervises Culvert Cleaning being done by labors.   Although Culvert cleaning is hot dirty work, normally there is never a problem with prison labors going out and doing work




Exit end: Workers used Duct-Tape to block end and allow to keep pipe clean of mud.   DONE!
