WIDACERM Cermet Grades
| TTI 15 | P05-P10 | For semi-finish and finish turning of steels with max, 38 HRC. Also suitable for machining of spheroidal graphite cast iron of medium to high hardness. |
| TTI 25 | P15-P25 | Tougher grade compared to TTI 15. Exhibits resistance to mechanical and thermal shacks, suitable for turning of steels with good wear resistance. |
WIDALON Coated Grades
| TN1000 | P05 - P20 M10 - M15 | Multi layer CVD coated grade with newly developed substrate by an innovative sintering process suitable for high speed machining. Recommended for light roughing and finishing of all steels under stable conditions. |
| TN 2000 | P15 - P30 M15 - M25 | Versatile grade for light to medium roughing of wide range of work material. This grade ensures strong cutting edge and is suitable for interrupted cuts. |
| TN 4000 | P25 - P40 M25 - M35 | A reliable choice for unfavourable machining conditions and interrupted cuts. It is a competitive grade for some stainless steel applications also. |
| TK 15M | P05 - P30 M10 - M25 | Universal coated grade for semi-finish and finish turning of moderately hard steels and cast iron at high cutting speed under favourable machining conditions |
| HK 150 | K10 - K25 M10 - M25 | Coated grade for finish and semi-finish turning of grey, malleable and nodular cast iron at high cutting speed and hardened steels at medium, cutting speed under favourable machining conditions. |
WIDAPLUS Coated Grades
