A new generation turning grade has been launched, offering one of the highest levels of productivity and versatility in the market today. The Pramet T9415 is the most advanced MT-CVD grade launched by Dormer Pramet in almost ten years. This fourth-generation grade covers a broad application range, replacing the previous T9310 and T9315. In addition, it also partly overlaps with grade T9325, giving T9415 one of the widest range of applications in steel turning. With a 30% thicker coating than the previous generation, the Pramet T9415 significantly improves tool durability by increasing resistance to wear and offers higher productivity by allowing for higher cutting speeds. Several testing users of the new grade have reported that their productivity has doubled while machining carbon and structural steels. Additionally, a new post-treatment process improves toughness and stability of the cutting edge resulting in improved reliability in interrupted cuts and unstable conditions, but the T9415 is still suitable for high cutting speeds. The insert seating area has been ground to improve stability and enhance heat transfer away from the cutting edge. This further helps to improve tool life, reducing the plastic wear on the cutting zones. Also, a gold TiN coating allows operators to better detect wear along the flank of the inserts.
