High-Performance Solid Carbide Undersize Milling Cutter

The solid carbide undersize milling cutter is a well-thought-out solution for precise contour and slot machining. Its specially designed undersize diameter allows operators to rough slots or keyways perfectly, leaving the ideal allowance for the final finishing pass. Featuring two flutes and a 30° helix angle, this tool ensures rapid chip evacuation during medium processing tasks. Thanks to its centre-cutting geometry, demanding plunging and ramping operations can be executed efficiently.
