Differences between Drilling and Boring

S.No. Drilling Boring
1 Drilling is performed to originate a hole. Boring is performed to enlarge the diameter of an existing hole.
2 Cutting tool used for drilling is known as drill. Cutting tool used for boring is known as boring bar.
3 Drilling can increase length of the hole but not diameter (limited to drill diameter). Boring can increase diameter of an existing hole but not length.
4 Drill is a double point cutting tool. Boring bar is a single point cutting tool.
5 Surface quality of drilled hole is not very good. Surface quality is better than drilling.
6 Drilling is first phase of hole fabrication. It does not require any special feature prior to operation. A pre-drilled hole (or a hollow portion made by casting) is mandatory for performing boring.
7 Material Removal Rate (MRR) in drilling operation is higher. MRR is lower than drilling.
