Gundrilling is characterized by small diameters. Diameters between 1 - 50mm [0.04 -2.00 inches] are common.

BTA/STS drills are used for larger diameter drilling, typically 20 - 630mm [0.79 – 24.8 inch].

Counter-boring covers large ranges of diameters up to 630mm [24.8 inch].

Pull boring is a special configuration of counter-boring in which the tool cuts chips when it is pulled out of the workpiece.

Trepanning tools cover a large range of diameters up to 500mm [20 inch].

Skiving operation is typically a finishing operation used when close diameter and roundness tolerance are required.

Bottom forming is essentially a form tooling operation to finish off the base of a hole.

The bottle boring operation is also known as internal profiling or chamber boring.
