The DNMG150608-TM T9225 is a premium negative indexable carbide turning insert designed for medium turning and high-performance machining operations. Manufactured from high-quality cemented carbide and coated with the advanced T9225 CVD coating, it provides excellent wear resistance, high toughness, stable cutting performance, and extended tool life. The TM chipbreaker offers effective chip control and is suitable for medium cutting conditions, including continuous and light interrupted machining. The insert features a 55 diamond shape with a 0 negative clearance angle, providing strong cutting edges and high rigidity. It is suitable for external turning, internal turning, facing, profiling, and medium machining of steel, stainless steel, cast iron, and alloy steel on CNC lathes and turning centers. The official Tungaloy specification lists a 12.7 mm inscribed circle, 6.35 mm thickness, 0.8 mm corner radius, and a recommended medium-cutting range.
