Inovatools’ Primus HPC aluminum roughing end mill

Inovatools’ Primus HPC aluminum roughing end mill is part of the company’s ta-C series, which is designed to provide thin, hard, smooth performance thanks to a ta-C coating that helps shops achieve higher productivity and quality.

With internal cooling and multiturning capability, the Primus is equipped to deliver consistently quiet, low-vibration, energy-efficient performance at high feed rates. To this end, the tool has a special knurled section with optimized chip control as well as the ta-C high-performance coating. This enables it to eliminate the usual problems in cutting aluminum, such as high adhesion tendency with built-up edges, welding deposits, chip caking and burr formation.

The company says that the ta-C coating combined with the microgeometry in conjunction with the cutting-edge preparation makes the tool highly resilient to prevent microchipping. This defect-free, cutting-edge design considerably increases the Primus’ service life. This is supported by the entwined profile’s special chip separators. These break the aluminum chips quickly and at an early stage, and, thanks to large chip grooves, they can be rapidly transported away from the engagement zone with cutting fluid. Not only does this bring a high level of process security, but it also is said to ensure low-vibration running for high surface quality, even during HPC roughing. This means that Primus tools operate with minimal vibrations, even at exceptionally high feed rates. The three-edged Primus is available in diameters ranging from 6.00 mm to 20.00 mm, with internal cooling, multiturning and straight and Weldon shank designs.


  • Swiss-Type Machines: More Than Just A Lathe

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
