Check the listing for details. 5pcs 10mm Solid Carbide End Mill 4 Flute HRC55 D10x 75 -4F TiSiN Coat CNC Cutter. Condition: New. Listed at 44.89 USD. Nano PVD coating: DLC and TiAlN (titanium aluminum nitride) coating lubricates the end milling cutter to stabilize high-temperature processing performance, making the milling cutter have strong adhesion and high wear resistance. Material: The tool is made of tungsten steel microalloy, which has high cutting performance and improves the wear resistance of the tool. Suitable for stainless steel, tool steel, and cast iron parts. Characteristics: Nano multi-layer coating, easy to process on heat treated materials below HRC55 ° - HRC58 °, from rough processing to precision processing. HRC65 hardness end milling cutter, 35 ° fine grinding spiral groove, 4 grooves x 2 cutting edges, making chip removal smoother. Advantages: Considering the strength and sharpness of the cutting edge, an appropriate negative rake angle design is adopted. The use of a large core diameter increases the stiffness of the grinding machine, making it stable during operation. Packaging includes: 5 pieces of HRC55 D10 x d10 x 25 x75-4FOn Jan 23, 2024 at 02:03:53 PST, seller added the following information:
