Coarse skin milling cutter (high-speed steel) is a rotating tool with one or more teeth used for milling rough machining. Basic information: Application of slot machining, woodworking milling cutters, etc. Classification of general and extended TICN coatings, TIN coatings, characteristics of rough machining, high processing efficiency. Basic overview: 1. Classified by coating, there are TICN coatings, TIN coatings, TIALN nano superhard coatings, and non coatings. 2. There are two types of lengths: regular length and extended length. Features: 1. Suitable for rough machining. 2. High processing efficiency. 3. Good chip removal performance and large chip removal capacity. 4. Has a high metal cutting rate. Applicable processing materials: stainless steel, aluminum alloy, mold steel, tool steel, carbon steel, alloy steel, cast iron, general iron, etc. Application: Mostly used for groove machining, woodworking milling cutters, and step surface machining. The groove of M42 high-speed steel rough milling cutter is fully ground, smooth, with good chip removal performance, high hardness, and high precision
