## Description

A TCT annular cutter cuts a ring of material and leaves a core (slug), giving faster, cleaner and more precise holes in metal than a twist drill with less load on the machine. The KZM series has a 50 mm cutting depth for thicker material. Use the matching PKZ pilot (ejector) pin for the diameter range.
