| Non Alloyed | 1 | 1 2 3 | C35, Ck45, 1020, 1045, 1060, 28Mn6 | Non-alloyed Steel Composition:Fe-C alloy (usually 0.1 to 0.6% carbon). Characteristics: Good machinability and high cutting speeds can be applied. When it has less than 0.25% carbon, it can be very stick reuirin ositive rake and small land inserts | Built-up edge Crater |

| High Alloyed | 3 | 10 10 | X40CrMoV5, H13, M42, D3, | and different heat treatments control features such as mechanical resistance and machinability. It’s important to follow the cutting speeds recommended according to the hardness of the steel, as it influences temperature as well as chemical and adhesive wears. | Crater |

| Austenitic | 4 | 14 14 | 304, 316, X5CrNi18-9 | Composition:Alloyed steel, more than 11% chrome (Cr). | Built-up edge Notch wear |
| M Duplex | 5 | 14 14 | X2CrNiN23-4, S31500 | Characteristics:Stainless steels do not stain, corrode, or rust as easily as ordinary steel. Usually they are difficult to machine because of its narrow range of cutting speeds. If the cutting speed is too low, the material sticks in the cutting edge, if it’s too high, the | Notch wear Crater |
| Ferritic & Martensitic | 6 | 12 13 | 410, X6Cr17, 17-4PH, 430 | high quantity of additives produces abrasive wears in the cutting edge. | Crater |
| Grey | 7 | 15 15 16 | GG20, GG40, EN-GJL-250, N030B | Composition:Fe-C alloy with 2.1 to 5% of carbon. It can be alloyed with Si, P, Mn and Ni. | Flank wear Crater |
| K Malleable & Nodular | 8 | 17, 19 17, 19 18, 20 | GG40, GG70, 50005 | Characteristics:Grey cast iron tends to be brittle, and malleable cast irons usually have a more ductile but less homogeneous micro-structure. Reinforced cutting edges will perform best. High productivity can be achieved by using high feeds. | Mechanical cracks |
| Fe, Ni & Co based | 9 | 31, 32 33 | Incoloy 800 Inconel 700 | Composition:Iron (Fe) based, Nickel (Ni) based or Cobalt (Co) based alloys and Titanium alloys. | |

| Ti based | 10 | 36 | TiAl6V4 | g , oxidation resistance. Relatively low cutting speed is recommended | |
| | 37 | T40 | due to their poor thermal conductivity. | |
| Steel | 11 | 38 38 | X100 CrMo13, 440C, G-X260NiCr42 | This group includes hardened and tempered steel up to 55 HRc, chilled and white cast iron up to 55 HRc. Machining success | |
| H | | 38 | | depends largely on clamping system rigidity, as cutting forces and | Crater |
| Chilled Cast Iron | 12 | 40 | Ni-Hard 2 | power consumption are high. Finishing represents the majority of the operations for this material group. | |
