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 diamete

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 one of the main tools for blast hole and well drilling, mainly used for large-scale open-pit mining, such as open-pit coal mines, iron mines, copper mines and molybdenum mines, also the non-metallic mines. With the increasing in variety of type, it’s also widely used in quarrying, foundation clearing, hydrogeological drilling, coring, tunneling in railway transportation department and shaft drilling in underground mines. The rock breakage by the tricone bit which used in mine is working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.
