Distinguish, differentiate, compare and explain what is the difference between Drilling and Reaming. Comparison and Differences.
Differences between Drilling and Reaming
| S.No. | Drilling | Reaming |
| 1 | Drilling is performed to originate a hole. | Reaming is performed to finish hole surfaces and to improve tolerance. |
| 2 | Cutting tool used for drilling is known as drill. | Cutting tool used for reaming is called reamer. |
| 3 | Drilling can increase length of the hole but not diameter (limited to drill diameter). | Neither diameter nor length can be increased substantially by reaming. |
| 4 | Drill is a double point cutting tool. | Reamer is a multi-point cutting tool. |
| 5 | Surface quality of drilled hole is not very good. | Reaming produces highly finished surface. |
| 6 | Drilling is first phase of hole fabrication. It does not require any special feature prior to operation. | Similar to boring, reaming can be performed only if a hollow part or hole exists. |
| 7 | Material Removal Rate (MRR) in drilling operation is higher. | MRR is poor; in fact, MRR is not an issue in reaming. |
