GTB 15.7-90-C25 Fixed Double-Edged Rough Boring Tool Bar | High Strength, Rust-Resistant MGIVR 2520 1.5 Standard metalworking tribology evaluations calibrated

Standard metalworking tribology evaluations calibrated to ISO 3685 testing frameworks demonstrate that Sumitomo’s signature Super FF Coat PVD coating architecture provides increased coating boundary density and superior interfacial bond integrity

use a carbide grade like TT8125

By pairing it with high-performance round insert configurations such as RCGT1003 or RPMT1003

This structure lowers overall tool pressure
