Key Characteristics and Applications
- Geometry: The round shape and positive rake angle make it a very free-cutting insert. This means it requires less power, generates less heat, and produces lower cutting forces than a negative geometry insert. This is excellent for:
- Shoulder milling
- Face milling
- Contour milling
- Slotting (with certain toolholders)
- Strength: The round shape is the strongest possible insert geometry, making it resistant to chipping and suitable for interrupted cuts.
- Versatility: The M-chipbreaker and PM grade make this a true "workhorse" insert for milling a wide variety of P-group materials (steel, stainless steel, cast iron).
- Surface Finish: The round insert and fine corner radius (0.8 mm) allow it to produce a good surface finish.
