YBC251 The substrate with good toughness and high security of cutting edge, in optimal combination with coating composed of MT-TiCN, thick layer of Al2O3 and TiN makes it suitable for steel semi-finishing. VNMG160408-PM is used for turning tools on lathes to process outer circles, end faces, threads, grooves, etc.1. Inserts shape: This is a negative blade with an 35 degree lozenge shape. 2. Inserts size: 160408 number indicates the blade size. 16 indicates the side length of the blade 04 indicates the thickness of the blade , and 08 indicates the radius of the cutting edge of the blade. 3. Application: This blade is suitable for cutting various materials, such as steel, cast iron, stainless steel and non-ferrous metals. 4. Cutting parameters: The specific cutting speed, feed speed and cutting depth parameters need to be determined according to the nature of the material being cut and cutting conditions. 5. Inserts material: carbide is a kind of high hardness material, with good wear resistance and thermal deformation resistance, suitable for high-speed cutting. Please note that the specific performance and application of the TNMG220408 may vary slightly by inserts’ brand and model.
