CNMG120408TK CA6515 (TJU00937)

The CNMG120408TK CA6515 is a high-performance indexable turning insert designed for medium turning of steel and stainless steel with an emphasis on toughness and thermal crack resistance. The CA6515 PVD-coated carbide grade delivers outstanding performance in interrupted cuts and fluctuating cutting conditions, while the TK chipbreaker — featuring a distinctive wavy, open-groove geometry clearly visible in the image — provides excellent chip breaking at medium to high feeds, particularly in steel and stainless steel.
