End Mill | Wear Suggestions: Speed too fast Too light of a feed Confirm concentricity of end mill in holder Verify speeds and feeds
End Mill | Tool life Suggestions: Work material harder than expected Verify speeds and feeds Recutting chips Too light of a cut Use different style of end mill
End Mill | Excessive noise Suggestions: Check part rigidity Verify speeds and feeds Too light of a cut Confirm concentricity of end mill in holder
End Mill | Burr Suggestions: Change end mill sooner / too much wear Verify speeds and feeds Increase spindle speed Decrease feed rate Use different style of end mill
End Mill | Part finish Suggestions: Confirm concentricity of end mill in holder Decrease feed rate Use different style of end mill Check coolant flow and location Check part rigidity
End Mill | Chattering Suggestions: Too light of a cut Leave more stock for finish pass Decrease axial depth Adjust speeds and feeds
End Mill | Breakage Suggestions: Decrease feed rate Decrease axial depth Use shorter tool or stub holder Resharpen earlier
End Mill | Chipping Suggestions: Check part rigidity Verify speeds and feeds Confirm concentricity of end mill in holder Decrease ramp angle or slow down approach Check coolant flow and location
Drill | Chip packing Suggestions: Add a peck cycle to clear chips Increase RPMs Reduce feed rate Check coolant flow and location
Drill | Chip welding Suggestions: Increase RPMs by 20% Confirm coolant concentration Check coolant flow and location
