Footnote: The Kola Peninsula covers an area of approx. 62,137 square miles and is known for its rich variety of ores and minerals. But it is also known as the
home of the world’s deepest hole – the Kola Super-

deep Borehole. The hole is the result of a scientific
project started in 1970 to drill as deep as possible
into the Earth’s crust. A number of holes were drilled,
the deepest of which reached 7.6 miles in 1989.

Ric-Man Construction used two
ECM 590 drill rigs, and HB7000 and
HB10000 hydraulic breakers to
undertake a challenging caisson
project in Dearborn, Michigan.

*The Association of Equipment
Manufacturers (AEM) developed
a testing system that provides an
objective standard for comparing
hydraulic breaker power output.
This simply gives contractors
the facts so they can make an
educated decision when choosing
a hydraulic breaker. Today only
a handful of companies publish
those standardized energy
ratings. When looking at a class of
breakers, one number means more
than the others – AEM measured
energy – the actual impact energy
needed to break an object.
ATLAS COPCO HAS SOME OF THE HIGHEST
IMPACT ENERGY RATINGS ACCORDING TO
TESTS OF THE AEM.

What it takes for
SUCCESS
Atlas Copco works with American Drilling to develop their
exploration fleet, including a Diamec U8 and Excore Bits

ATLAS COPCO EXCORE RANGE — DIAMOND CORE DRILLING BITS
Three application segments:
•Excore for soft to medium-hard rock with abrasive
and fractured to competent formations (Matrix 1-4)
•Excore for medium-hard to hard rock with slightly abrasive
and slightly broken to competent formations (Matrix series 5-8)
•Excore for hard to very hard rock with competent formations (Matrix series 9-10))
Each Excore type is also available with various crown designs: the Extended
T
Channel Flush (ECF) for broken to competent formations; the patented JET
profile for fast cutting in competent formations; and a face discharge design
for extremely broken and triple tube applications.
Combining these crown profiles with various crown heights ranging from 10-166 mm
means each Excore bit type will cover a wider range of rock conditions.
