Group of Bits

CC KRUSHER BIT
Krusher
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

Flat Face
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: Very Hard
Hole Straightness: Fair
Penetration Rate: Good

CONCAVE BIT

Concave
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: Fare

DROP CENTER BIT

Drop Center

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. This is a custom-made design, as it is not very common nowadays.

Formation: Sloping and Broke, Medium to Hard
Hole Straightness: Good
Penetration Rate: Average

CONVEX BIT

Convex

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
