Designed for medium hard rock. Bits with ballistic buttons perform especially well in nonabrasive or medium abrasive rock formations.

To be used in the same applications as -6076-67 when you have rock formations that also create hole deviations.

Perfect in slightly more abrasive formations where there is accelerated button wear or in medium to hard rock whenballistic buttons have a tendency to break.

Use in the same applications as -6076 when you have rock formations that also create hole deviations.

Ideal for medium hard rock when the rock formation causes heavy gauge wear on the bit. Can also be used in very hard and abrasive rock formations.

To be used in the same applications as -5076 when you have rock formations that also create hole deviations.

A new bit design for hard to very hard abrasive rock. The asymmetrical button pattern gives excellent rock crushing. A shorter head and larger clearing angle allow for better flushing of cuttings. is used for the same applications.

The two types of fullballistic button bits, model 5xxx -47-66 and model 6xxx-2166 are developed specially for drilling in soft formations. The penetration rate is very fast due to the high button protrusion. Excellent flushing concentrated to the front.

Traditional chisel bits in cross-and Xtype formations forextremely abrasive rock. Ideal for soft formations that cause snakeskin problems for carbide. Produce straight holes. X-type bits are used for larger hole dimensions.
