TECHNICAL FEATURES
- Premium cutters. Resistant to abrasive wear and impact loads, the cutters allow to increase the drilling interval and mechanical rate of penetration.
- Reinforcement of the calibrating part. A special coating of the bit caliber prevents its wear and loss of diameter.
- The stepped configuration calibrating platform ensures stability without limiting the lateral aggressiveness of the bit cutting.
PRESERVATION INFORMATION
The connecting thread and thrust shoulders of the product are protected from corrosion by preservative grease in accordance with GOST 9.014-78.
