Medium to Medium-Hard Formation

Application: For use in moderately abrasive consolidated formations with compressive strength ranging between 140 – 485 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic formations

Cutting structure: These bits are characterized by moderately spaced conical inserts with medium projection. This configuration promotes good penetration rates in medium hard and moderately abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.

• Compression Strength: 20,000 – 70,000 psi
• Drilling Speeds: 60 – 100 rpm
• Jet Circulation: All sizes
• Weight on Bit (WOB): 2,500 – 7,000 lbs/in of bit diameter
