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

INTERRELATIONSHIP BETWEEN INSERTS REQUIREMENTS AND THE FORMATION
Formation Characteristics | Insert Spacing | Insert Properties | Penetration and Cuttings Production | Cleaning Flow Rate Requirement |
| Soft | Wide | Long and sharp | High | High |
| Medium | Relatively wide | Shorter and stubbier | Relatively high | Relatively high |
| Hard | Close | Short and rounded | Relatively low | Relatively lower |
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.
