Workpiece examples include:

Deburr, Form and Finish of Rifle Barrel
Special Adjustable Hollow Mill deburrs, forms, and finishes "crowning" radius on the end of rifle barrels. The range of adjustability allows the customer to turn the complete range of barrel sizes with the same tool. Blade set includes two precision ground radius-generating blades.
A world leader in the manufacture of handguns sought a way to improve the manufacture of revolver barrels.
- The process involved heavy metal removal including a heavily interrupted cut from extruded steel that is turned down to a diameter of .675.
- Multiple passes and frequent insert changes caused the cycle time and tool life to be unacceptable.
Genesee designed special GEN-DEX hollow mill using standard inserts in five adjustable insert holders.
- Cycle time was decreased by approximately one minute.
- The number of parts produced prior to indexing the inserts increased from 15 to 150.
