Objective
Improve tool performance and consistency by honing the cutting edges of solid carbide drills — strengthening the edge, reducing micro-chipping, and improving surface finish during machining.

Solution
Bel Air developed an automated edge-honing process using the Vertical Drag Finisher to strengthen and refine the drill’s cutting edges. The engineered edge radius reduces the risk of chipping at high cutting speeds and improves cutting efficiency in tough materials.
The automated process:
- Creates a controlled cutting-edge radius
- Reduces micro-fractures from grinding
- Improves tool life and consistency between tools
- Minimizes cutting forces and burr formation during drilling
- Eliminates manual finishing steps for higher production throughput
This solution provides a repeatable method for tool manufacturers seeking tighter quality control and better performance from precision carbide drills.
