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

Issues on GFi65Y

Gauge durability- Need more inserts on gauge

Durability mainly in the inner row

Lost Cones

Row Scraping Distribution Comparison

So wheres the ROP is going to come from?- Lower journal angle

- Higher gauge scraping distance

- Increase scraping in the inner rows

8 FHi70YOD1RD : Conclusions



- Larger and more ATLAS in the heel row

- Reduce radial gauge load

ROP from inner rows


- 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
