Picks and Bits for Higher Productivity
New developments in its ProBore roof bits
and ProPoint high-efficiency picks are
delivering measurable benefits in produc-
tivity and safety for underground mining
operations, according to Kennametal.
ProBore roof bits feature a new twisted-
body design specifically engineered for
improved operation. Unlike traditional
straight-body designs where dust and other
materials clog or otherwise slow down
equipment, the new ProBore twisted-body
design acts like a flute on a twist drill, effi-
ciently channeling dust away, simultane-
ously reducing clogging and lowering cut-
ting forces, making drilling more efficient.
An arched tip support increases the seating
area for the bit, reducing break-
age and increasing tip life. Two
point styles are available, one
with a split nose for more
demanding operations; and a
solid nose style for increased
penetration rates. The ProPoint
high-efficiency tip features a
new thinner cross-section that
reduces respirable dust and low-
ers power consumption while
increasing material
size. A proprietary
body profile with a
narrow bottom tip
reduces breakage and
extends service life,
meaning more rock
cutting with signifi-
cantly fewer motor
trips for continuous
mining machines.
