DOHRE CNC Boring Drilling Hole Cutting Tools

A carbide boring tool, also known as a boring bar or internal boring cutter, is designed to enlarge or finish internal holes with high precision.

It is widely used in CNC machining for molds, automotive parts, and precision components where accurate internal diameters and surface quality are critical.

Compared to drilling, boring provides superior dimensional accuracy and surface finish, especially in deep holes or tight tolerances.
