Smith Bits gauge conditions
Gauge durability is a concern and need to be improved upon
Inner row needs to be improved too if the gauge is performing

8 FHi70YOD1RD : Conclusions
Gauge durability- Need more inserts on gauge
- More inserts in the adjacent to gauge area
- Larger and more ATLAS in the heel row
- Reduce radial gauge load
ROP from inner rows
- Lower journal angle
- Higher gauge scraping distance- Carbide grade
- Cone force balanced
To tackle lost cones issues
- Thicker cone shell- Shallower grooves on the cone shell
- Half carburization on the ball race
