Reamer | Not evacuating Suggestions: Verify speeds and feeds Check coolant flow, location, and concentration Reamer worn
Reamer | Wear Suggestions: Speed too fast Too light of a feed Confirm concentricity of reamer in holder Check coolant flow, location, and concentration
Reamer | Tool life Suggestions: Work material harder than expected Verify speeds and feeds Not evacuating chips properly Too light of a cut
Reamer | Part finish Suggestions: Reamer worn Verify speeds and feeds Confirm concentricity of reamer in holder Check coolant flow and location Check part rigidity
Reamer | Hole not straight Suggestions: Hole was not drilled properly Leave more stock before reaming Confirm concentricity of reamer in holder Check part rigidity
Reamer | Hole diameter too small Suggestions: Leave more stock before reaming Reamer worn Check coolant flow and concentration Resharpen earlier
Reamer | Hole diameter too large Suggestions: Check part rigidity Verify speeds and feeds Confirm concentricity of reamer in holder Confirm diameter of reamer Check coolant flow and location
End Mill | Wall not straight Suggestions: Decrease feed rate Decrease axial depth Use shorter tool or stub holder Use different style of end mill
