Sandvik Coromant’s CoroMill 390 is now available with the company’s Silent Tools technology for more efficient machining of parts such as engine mounts as well as deep pockets on titanium-frame parts for the aerospace industry. Pockets are the most common feature in titanium structural parts for aircraft, often featuring depths of more than four times the diameter of the cutter, the company says. The updated tool range is designed to meet the resulting need for process stability and quality as well as increased metal-removal rates.

CoroMill 390 Silent Tools provide light-cutting insert geometries and high-performance grades that deliver low cutting forces and vibration-free machining for secure, cost-effective milling, the company says. These tools can be ordered in diameters ranging from 20 to 32 mm with both the new 07 insert size as well as insert size 11. They are available in either cylindrical shank or Coromant Capto coupling.
