What Our Customers Are Saying…
“I am a happy owner of several Terminator
Reamers. I work out of the San Francisco area
and a good portion of my drilling is in sticky,
swelling clay conditions. The Terminator Reamer
outperforms equivalent reamers hands down.
The Terminator Reamers have superior cutting,
mixing, and pumping action, which reduces my
rotary and pullback pressures and can be pushed
back through the hole with ease. I am not afraid
to use these reamers in most all soil conditions.
I told my sales rep that whomever designed this
reamer should be given an award because this
reamer has given me such great success.”
Ty Amundson
Precision Drilling / San Jose, CA

■ One tough, solid reamer with more cutters
than any other reamer in its class
■ Angled fluid jets shoot water opposite the
reamer rotation
■ Each cutter takes off only 1/4" more soil
than previous stage resulting in a smooth,
efficient cutting action
■ Hardfacing on all wear areas
■ Curved backup blades for easier pushbacks
REAMERS
OGRE
■ Slow taper and deep spiraled fluting
combine to give the Ogre maximum

“We have used both 14" and 18" Ogre reamers on our
Vermeer D50x100. First was going across the St. Verain
River in Colorado. Next we used one to cross the Platte
River. We will never cross these rivers again without an
Ogre reamer. It made the pullback 10 times easier.”
Beau Kraus
EBC Enterprises, Inc., Erie, CO
“I had the first opportunity to test the Ogre and we put it
up to a big challenge. We were drilling hard compacted
rocky ground, our longest and most difficult bore on the
whole job. After burning through several stacked plate
reamers, I called my Melfred Borzall rep and he outfitted us
with the Ogre. Even after boring 225 feet, the teeth on the
Ogre looked brand new. It performed so well on this
job, I wish we could have had it a month sooner.”

■ Large shark teeth carbide cutters give an aggressive
yet smooth cutting action
■ Angled placement of cutters and spiral pattern results
in an excellent mixing and pumping action
“We had a tough, 475' shot across the Wind
River in Wyoming. To drill out we had to use
a single roller cone bit on our JT2720.
Cobbles and blue shale most of the way.
We needed a hole opener but didn’t have
enough money in the job to justify it.
We tried an 8" Sabertooth from Borzall
and had no trouble with the pullback.”
Drew Kaup

What will you connect
to the front of your reamer?
Based on your machine capacity, choose a reamer series:
Standard “T” reamers for machines up to 30,000 pounds pullback
and 4,000 ft-pounds torque.
Heavy Duty “TH” for machines up to 80,000 pounds pullback
and 10,000 ft.-pounds of torque.
Select the part number for the Reamer Body you want, based on
the reamer size and style.
