How to Order:
Ordering is simple. The COFA tool provides different blade and spring options
to create the most effective tool for any application depending on the hole
geometry and type of material being machined.

1. Choose the tool that best fits the hole diameter.
2. Choose the blade that best fits the hole geometry.
3. Choose the spring that best fits the material.
