Correct thread geometry and cutting parameters are important for producing accurate and functional threads.

6. Reamers

Reamers are finishing tools used to improve the dimensional accuracy and surface finish of existing holes.

A typical machining process may involve drilling a hole slightly undersize and then using a reamer to achieve the required final dimension.

Reamers can be used when tighter hole tolerances and improved surface quality are required.

They are commonly used in precision engineering and component manufacturing where accurate hole dimensions are important.

7. Boring Tools

Boring tools enlarge or finish existing holes with controlled material removal.

CNC boring tools can be used for:
