The Micro 100 Ball End Mill is a 4 flute carbide end mill with a ball end. It has a 1/4" shank diameter and is available in multiple diameters from 1/8" to 1/2". The ball end geometry allows milling of 3D contoured surfaces. Carbide construction provides wear resistance and tool life. It can machine steels, stainless steels, cast iron, non-ferrous metals, and non-metallic materials. Recommended applications include 3D profiling, contouring, slotting, and plunging. The ball end reaches into 3D contours, while the flutes efficiently chip away material.
