| CC KRUSHER BIT The CC KRUSHER bit combines three distinctly different face angles, while providing the best features of the Concave and the Convex designs. Specifically, the CC Krusher offers both straight-hole drilling and excellent penetration rates. | Formation: Medium to Hard Hole Straightness: Average Penetration Rate: Excellent |
| FLAT FACE BIT The FLAT FACE bit is simple and robust face design, best suited for very hard formations. It can also be used in soft formations where vertical deviation is not a priority. | Formation: Good Hole Straightness: Fair Penetration Rate: Excellent |
| CONCAVE BIT The CONCAVE bit is suited for most drilling conditions, as this design holds a very straight hole due to the tapered recess in the face of the bit. This recess or so-called "dish" causes a slight coring action, which helps keep the hole straight, while providing for excellent penetration and good air flushing of the hole. | Formation: Medium to Hard Hole Straightness: Very Good Penetration Rate: Fair |
| DROP CENTER BIT The DROP CENTER bit, as it name suggests, features a recess in the impact face. This recess provides a coring action, which helps keep the hole straight. | Formation: Sloping and Broke, Medium to Hard Hole Straightness: Good Penetration Rate: Average |
| CONVEX BIT The CONVEX bit is suited for very hard and abrasive formations as it incorporates two different gage rows leading up to the flat impact face. The inner gage row helps to protect the outer row from excessive wear. | Formation: Medium to Hard Hole Straightness: Average Penetration Rate: Excellent |
