Carbide Supported Edge<br />
CSE cutters feature an extended<br />
chamfer edge which reinforces<br />
the diamond table against<br />
detrimental blows. CSE cutters<br />
delay the onset of fracturing<br />
and cutter wear, dramatically<br />
extending cutter life.<br />
Polished Cutters<br />
Patented “Black Ice” polished<br />
cutters reduce shear forces,<br />
significantly improving cuttings<br />
removal, thus reducing torque<br />
and increasing overall penetration<br />
rates.<br />
STAR Gauge<br />
STAR bits utilize a more durable<br />
gauge pad with a tighter diamond<br />
setting for enhanced gauge holding<br />
capabilities in directional and<br />
abrasive applications.<br />
Updrill Feature<br />
A standard feature which assists<br />
the drilling operation when tight<br />
hole conditions are encountered<br />
or backreaming is required.<br />
Wear Knots (optional)*<br />
Matrix pads, located behind the<br />
cutters restrict the depth of cut,<br />
reducing torque fluctuations.<br />
Directional Feature (optional)<br />
The cutter’s backrake has<br />
been increased, reducing torque<br />
variations.<br />
*Only on certain styles<br />
