A new-generation turning grade is now available that its manufacturer Dormer Pramet says offers one of the highest levels of productivity and versatility available on the the market today. The company says that its T9415 is the most advanced MT-CVD coated turning grade it has launched in almost 10 years, bringing greater stability and performance in a variety of cutting conditions.

This fourth-generation Pramet grade covers a broad application range, replacing the previous T9310 and T9315. In addition, the new grade partly overlaps with the company’s T9325 grade, giving T9415 one of the widest range of applications in steel turning.

Featuring a 30% thicker coating than the previous generation, the Pramet T9415 improves tool durability by increasing resistance to wear and offers higher productivity by allowing for higher cutting speeds. Additionally, a new post-treatment process improves toughness and reliability of the cutting edge, especially in interrupted cuts and unstable conditions. The T9415 is also suitable for high cutting speeds.

Notably, grinding of the insert seating area improves stability and enhances heat transfer away from the cutting edge. This capability further helps to improve tool life, reducing the plastic wear on the cutting zones. Also, a gold TiN coating allows operators to detect wear along the flank of the inserts.

Using the latest technologies, Pramet T9415 inserts have optimised cutting-edge geometry that reduces cutting forces and enhances performance. Along with saving energy, the inserts themselves are manufactured using the latest production technologies, which supports a more sustainable and environmentally friendly offer.
