Drilling vs Boring vs Reaming: What's the Difference ...

Boring is a cutting process that involves the use of a single-point cutting tool or boring head to enlarge an existing hole in a workpiece. This is in stark contrast to drilling, which is performed to create an initial hole in a workpiece. Boring processes are typically performed using a lathe, milling machine or a horizontal boring mill.

Finish Boring vs. Reaming | Cutting Tools | Machining ...

A finish boring head. In terms of hole quality, finish boring heads typically achieve tolerances within IT5 and surface finishes above Ra 1 micron. The main drawback to a finish boring head is feed time as it only has one tooth for cutting. Also, with one tooth doing the cutting, tool life is generally less than with reamers.

Drilling VS Reaming VS Boring VS Honing, What Is The ...

Drilling, boring, reaming, and honing are common processes used by manufacturing companies. All processes involve, to some extent, creating new holes in the workpiece or modifying existing holes. Drilling is the process of drilling, while boring enlarges the diameter of an existing hole. Reaming and honing are used to improve the surface finish ...
