Soft to Medium-Soft Formation

 

Application: For use in less abrasive softer formations with compressive strength ranging up to 140 Mpa, such as shales, limestones, carbonates and most metamorphic formations.

Cutting structure: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.

  • Compression Strength: 15,000-25,000 psi
  • Drilling Speeds: 80 – 110 rpm
  • Jet Circulation: All sizes
  • Weight on Bit (WOB): 2,000 – 5,000 lbs/in of bit diameter

Advantage:

 

1. Strictly select the material to ensure the reliable quality. Bad steel and tungsten carbide inserts won't be used.

2. Strictly act according to the ISO9001 standard, and control by full-scale inspection.

3. Sales and support people are highly trained in the latest rock drilling technology and can offer you expert advice on what products will best fit a specific end use application.

Application

 

Tricone drill bit is the best all-purpose drill bit and can be used for many different types of rock formations, such as Soft Rock Formations (consist mainly of sand, clay, limestone or shale), Medium Rock Formations (calcites, dolomites, hard limestones, and some hard shale), Hard and Abrasive Formation (hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones).
