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.
