| FAULT | CAUSE | REMEDY |
| Bore too large | Reamer too big | Controlling the reamer diameter |
| Alignment reamer to machine not precise | Correct alignment or use compensation holder | |
| Built up edge | Correct cutting speed and feed, use another coolant | |
| Unsuitable coolant | Use another coolant | |
| Reamer is not running true | Use compensation holder | |
| Depth of cut too small | Correct depth of cut | |
| Papered bore | Faulty alignment | Correct alignment or use compensation holder |
| Built up edge | Correct cutting speed and feed, use another coolant | |
| Bore not true, shows chatter marks | Concentricity an alignment error too large | Correct concentricity and alignment, or compensation holder |
| Wrong cutting geometry | Use face cutting reamer | |
| Deformation through fixation of the work piece | Correct fixation of the work piece | |
| FAULT | CAUSE | REMEDY |
| Surface quality unstatisfactory | Cutting edges blunt | Regrind correctly |
| Reamer does not run true | Correct concentricity or use compensation holder | |
| Wrong machining data | Check back on data as instructed | |
| Bad chip flow (insulfficient coolant) | Use tool with internal coolant supply, supply proper coolant with strong jet | |
| Feed marks in bore | Cutting edges fragment | Regrind or replace reamer |
| Built up edge | Correct cutting data | |
| Reamer jams | Reamer taper too slight because of wear relieving | Regrinding with adequate reamer taper |
| Circular land too wide | Make a relief grind as instructed | |
| Bore too small | Worn reamer | Expand, regrind or replace reamer |
| Wrong coolant | Use another coolant | |
| Depth of cut too small | Increase cutting depth | |
| Deformation through fixation of the work piece | Correct fixation of the work piece |
