Teeth and Tungsten Carbide Insert Buttons

 

- Length and geometry relate the rock strength
- Size of the cone and bearing structure affect the teeth

- Teeth design criteria are:
- Spacing and interfitting of teeth governed by tooth strength, depth and included angle
- Shape and length, dictated by formation characteristics
- Types of teeth, milled or inserted

- Log slider and widely spaced teeth used for soft rock

- Long teeth allow results in breaking greater volume

- Wide spacing allows easy removal of drilled cuttings

- The included angle for soft rock from 39 to 42

- Medium hard would have a moderate number of teeth and 43 to 45 included angle

- Hard rocks need 45 to 50 included angle

- Milled teeth are faced with hardening metal to reduce wear

- Milled tooth bits are suitable for soft formation

- Insert are used for hard formation

- There are several types of insert to suit the hardness

- Chisel-shaped for soft rock

- Round or spherical for medium and hard rocks
