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
