12.  Fast penetration rates.
 Face design allows for increased body support for gauge
carbide. There are two gauges and the inner gauge row
helps to protect the outer row from excessive wear.
 Well suited for hard and abrasive formations.

13.  Face slots help eliminate bit plugging in softer
zones. More carbide to surface contact for better rock
fracture. It is a simple and a robust design, well
suited for medium to hard rock formations.
