Cutting Insert With Six Edges
Sumitomo's 55-degree Sumi-Turn T-Rex triangle insert is said to be a cost-effective replacement for 55-degree DNMG. The T-Rex features six cutting edges compared to the conventional four edges. Its contoured edges result in clamping within the turning system and provide for accurate insert indexing, according to the company.
Sumitomo's 55-degree Sumi-Turn T-Rex triangle insert is said to be a cost-effective replacement for 55-degree DNMG. The T-Rex features six cutting edges compared to the conventional four edges. Its contoured edges result in clamping within the turning system and provide for accurate insert indexing, according to the company.
The insert is available in three grades: AC700G for finishing steels and stainless steels and for roughing cast irons; AC2000 for general purpose machining of steels, stainless steels and cast irons; and AC3000 for heavy roughing and interrupted machining of steels and stainless steels. Maximum cutting depth is 2.5 mm (0.100"). LU chipbreakers allow for finish to medium cutting, while GU chipbreakers enable medium to rough cutting.
These inserts are compatible with T-Rex turning toolholders and boring bars.
