Composites
Composites are often machined using standard metal cutting end mills, resulting in lifting and fiber pullout. For optimal performance in difficult-to-machine high-fiber or abrasive composite materials, browse our selection of End Mills for Composites.

Chipbreaker
This offering includes optimized geometry with chipbreakers, designed to efficiently shear fibers and shorten chips for improved chip removal.
Compression
This offering features counteracting flute geometries which compress material inwardly to avoid burrs, tear out, and delamination.
Diamond Cut
Harvey Tool's Diamond Cut End Mills for Composites are offered in End Mill or Drill Styles, each of which is optimized specifically to avoid common composites mishaps.
Finishers
The slow helix of this line of finishing end mills for composites improves part finish and minimizes fraying of fiber-reinforced and layered materials.
