Advanced Turning Grade Gains Application Versatility

A new-generation turning grade has been launched by Dormer Pramet, offering moldmakers a high level of productivity and versatility. The Pramet T9415 is said to be the most advanced MT-CVD grade launched by Dormer Pramet in almost 10 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 a wide range of applications in steel turning.

A 30% thicker coating than the previous generation improves tool durability by increasing resistance to wear and offers higher productivity by enabling 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, while still being suitable for high cutting speeds.

Dormer Pramet says 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 enables operators to better detect wear along the flank of the inserts.

Using the latest technologies, the Pramet T9415 inserts have optimized cutting-edge geometry which reduces cutting forces, enhances performance and saves energy.
