TS (AlTiN-based) Inserts for Both Soft and Hard Milling

Our new high-performance TS insert grade offers dramatically improved performance versus our GLH grade.

TS-coated inserts boast the strongest adhesion characteristics of any Dapra grade and feature added elements for extra heat and wear resistance. Chip flow is improved due to inherent process consistency, providing the least friction at the chip-tool interface.
