TAR Bits
STAR drill bits are a premium line of
Tricone bits designed specifically for
slim hole wells. Both steel tooth and
tungsten carbide insert bits employ
many of the features found in
Hughes Christensen’s widely
accepted GT line. In addition,
improvements in bearing
geometry/metallurgy, compensator
design and shirttail
protection have combined to
make these the most reliable,
high performance slimhole
tricone bits available.
