Down Cut End Mills

Down Cut end mills direct chips downward during cutting, helping produce clean, tear-free top edges and improved surface finish.

  • Best for: laminates, thin materials, plastics, composites, and applications where top-edge quality is critical
  • Why choose it: reduces top-surface chipping and tear-out compared to up-cut geometries
  • Common uses: shallow slotting, profiling, and finishing passes on delicate surfaces
  • Important consideration: because chips are directed downward, shallow depths of cut and proper chip evacuation are recommended to minimize chip re-cutting, heat buildup, and tool wear—especially in deeper slots
