Difference Between Drilling and Reaming

09.06.2019· Cutting tool used in drilling operation is called Drill. Cutting tool used in reaming operation is called Reamer. Metal cutting drill usually consists of two cutting edges. So drill is considered as a double point cutting tool. Reamer contains large number of cutting edges (minimum 4). So reamer is a -point cutting tool. Surface of a drilled hole is not highly finished (i.e. high surface ...

Difference Between Drilling, Boring and Reaming

09.06.2019· Differences between drilling, boring and reaming. Purpose of operation. Drilling is carried out to originate a cylindrical hole. So it can create a hole on a solid surface. Boring is performed to enlarge an existing hole or to convert a cylindrical hole into a taper hole. Reaming is carried out to highly finish the surfaces of a hole. Its purpose is to improve dimensional accuracy and ...

Reaming - eFunda

Reaming is a process which slightly enlarges a pre-existing hole to a tightly toleranced diameter. A reamer is similar to a mill bit in that it has several cutting edges arranged around a central shaft, as shown below. Because of the delicate nature of the operation and since little material is removed, reaming can be done by hand. Reaming is most accurate for axially symmetric parts produced ...

ream - Schlumberger Oilfield Glossary

vb. [Drilling] To enlarge a wellbore. Reaming may be necessary for several reasons. Perhaps the most common reason for reaming a section of a hole is that the hole was not drilled as large as it should have been at the outset. This can occur when a bit has been worn down from its original size, but might not be discovered until the bit is tripped out of the hole, and some undergauge hole has ...
