2. Insert Size: The next number in the nomenclature represents the size of the insert, typically the width or diameter of the cutting edge. For example, a 10-mm insert would be designated as "10".
3. Corner Radius: If the insert has a rounded cutting edge, the next number indicates the radius of the curve. For example, an insert with a 0.4-mm radius would be designated as "04".
4. Insert Thickness: The next number in the nomenclature represents the thickness of the insert, typically the distance from the top of the insert to the bottom of the cutting edge.
5. Cutting Material: The next letter in the nomenclature indicates the type of material used for the cutting edge, such as C (carbide), P (ceramic), or M (CBN).
6. Coating: If the insert is coated with a layer of material to improve its performance, the next letter or letters in the nomenclature indicate the type of coating used, such as T (titanium nitride) or P (polycrystalline diamond).
7. Cutting Direction: The final letter in the nomenclature indicates the cutting direction of the insert. Common designations include M (medium), L (light), and H (heavy), which indicate the amount of material being removed by the insert.
