tricone roller bit with high compressive strength
Aoolicable formation:
Medium hard with high compressive strength and hard stringers,such as limestonemhard sandy mudstone and sandstone,etc
Main characteristics of the bit:
Conical compacts in inner row,spherical compacts in outer row.
Recommended parameters:
Normal WOB 0.50-1.05KN/mm

Tricone bits also named roller bits, typically they are used for oil & gas drilling, but now tricone bits are also used for mining, quarrying, water well drilling, etc. different rock formation with its different categories and perfect efficiency.
Feature of 200-40rpm teeth tricone roller bit
1. High-strength, high flexibility, high temperature and high wear resistance.
2. High-precision metal seal.
3. Locking roller ball, to adapt to high-speed.
4. The use of high strength high toughness carbide teeth,
5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.
6. Cone bit to adapt to the soft, medium and hard of various strata.
