| PROBLEM | SUGGESTIONS |
| Hole diameter too large | Check part rigidity Verify speeds and feeds Confirm concentricity of reamer in holder Confirm diameter of reamer Check coolant flow and location |
Hole diameter too small | Leave more stock before reaming Reamer worn Check coolant flow and concentration Resharpen earlier |
Hole not straight | Hole was not drilled properly Leave more stock before reaming Confirm concentricity of reamer in holder Check part rigidity |
Part finish | Reamer worn Verify speeds and feeds Confirm concentricity of reamer in holder Check coolant flow and location Check part rigidity |
Tool life | Work material harder than expected Verify speeds and feeds Not evacuating chips properly Too light of a cut |
Wear | Speed too fast Too light of a feed Confirm concentricity of reamer in holder Check coolant flow, location, and concentration |
Not evacuating | Verify speeds and feeds Check coolant flow, location, and concentration Reamer worn |
