What is the difference between boring and reaming?

Question

Accepted Answer

Boring enlarges existing holes while reaming improves the surface finish and accuracy of holes.

Boring is used to enlarge existing holes to a specific diameter, while reaming is used to improve the surface finish and accuracy of holes.
Boring is typically done before reaming in the machining process.
Boring is usually done using a single-point cutting tool, while reaming is done using a multi-edge cutting tool.
Examples: Boring a hole in a cylinder block to fit a piston, and then reaming the hole for a smoother finish and precise dimensions.

Accepted Answer

Boring is a machining process where the internal diameter of an existing hole is enlarged and reaming is a machining process used to give a finish to the interior surface of a machined hole.
