ROLLER CONE BIT CONE DESIGN
One important factor which affects journal angle is the degree of meshing or interfit (i.e. the distance that the crests of the teeth of one cone extend into the grooves of the other). The amount of interfit affects several aspects of bit design.
1. It allows increased space for tooth depth, more space for bearings and greater cone thickness
2. It allows mechanical cleaning of the grooves, thus helping to prevent bit balling
3. It provides space for one cone to extend across the centre of the hole to prevent coring effects
4. It helps the cutting action of the cones by increasing cone slippage.
