Tool Life Strategy

Replacing a $15 insert 2 minutes early is always cheaper than replacing a $3,000 spindle or scrapping a $500 part.

Operator Warning

Once tool wear reaches a certain point, cutting forces increase exponentially. This is when the most "unexpected" breakage occurs.

Variables to Watch:
  • Chip Color: Sudden changes in chip color (blue/dark) indicate edge breakdown.
  • Surface Finish: A "dull" or "tearing" appearance means the tool is finished.
  • Machine Load: Watch your spindle load meter for increases in the same cut.
Pro Tip: Use Taylor's Tool Life Equation for more complex speed/feed adjustments if you are optimizing for maximum production.
