Rope thread Weight approx kgmm inch mm inch For 89, and mm reaming button bits. Standard skirt. Designed for medium hard rock. Bits with ballistic buttons perform especially well in non- abrasive or medium abrasive rock formations.

Perfect in slightly more ab- rasive formations where there is accelerated button wear or in medium to hard rock when ballistic buttons have a tendency to break. Retrac skirt. To be used in the same applications as 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. Use in the same applications as when you have rock formations that also create hole deviations. Flat or drop centre front. Retrac or standard skirt. Ballistic or spherical buttons. 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.

Model is used for the same applications. Insert bits Cross- and X-type bits. Traditional chisel bits in cross-and X- type formations for extremely abrasive rock. Ideal for soft formations that cause snakeskin problems for carbide. Produce straight holes. X-type bits are used for larger hole dimensions. Soft rock bits Full-ballistic button bits. The two types of full- ballistic button bits, model 5xxx and model 6xxx 66 are developed spe- cially for drilling in soft formations.

The penetration rate is very fast due to the high button protrusi- on. This is done because of the fast initial wear on button bits. When it is of importance, also consider that the hole is always 1—3 mm bigger than the bit dimension depending on rock formation.
