Feature: 1. The milling cutter is made of tungsten steel, with high hardness and good wear resistance. 2. The flute is processed by mirror polishing process with fast processing speed and high finish. 3. When using a 4‑flute milling cutter to process materials, the chips are discharged from the front end of the milling cutter, which has a better chip removal effect. 4. The head of the milling cutter has a nano‑blue coating to ensure a glossy cutting exterior when cutting chips. 5. Suitable for processing planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines.
