milled tooth tricone bit
Aoolicable formation:
soft to medium soft with low compressive strength or soft with harder stringers,such as hard gypsolyte,soft limestone and sandstone,etc.
Main characteristics of the bit:
Hardfaced tooth surface and gage,high compact exposuer,with gage compacts,and a row of trimmers is added between gage row and heel row.
Recommended parameters:
Normal WOB 0.35-1.05KN/mm
Rotary speed 120-60rpm
tricone bit , steel tooth bit , drill cone bit , tricone bits,rotary bit
1.This type of bits are used in low press resistance soft to medium formation,shales,clay,salt,etc.,It can work in a high RPM and low WOB with fast drilling speed.
2. Surface of cones and teeth are hard enhanced to extend the working life of bit.
3. Teeth distributed optimal design largely improve the working efficiency of breaking down
