Standart line presents open bearing bits with steel teeth or tungsten carbide inserts. They are designed for a wide range of applications, drilling with low speed turbines, downhole hydraulic motor or for rotary drilling. Standart bits use both friction and roller bearings.
This product line may have either milled teeth or TC I. To increase steel teeth life, steel teeth are hardfaced with wear-resistant tungsten carbide based material. Depending on the rock hardness, either side surfaces or side and end surfaces of steel teeth are hardfaced. The gauge may be protected with tungsten carbide inserts. For additional protection against gauge loss, a near gauge of tungsten carbide inserts may be used.
