The Multi Flute product family is designed for high speed machining and optimized roughing applications in ISO M and ISO S materials. These new tools are especially beneficial for the aerospace segment, particularly when customers need to increase productivity – they specialize in delivering high metal removal rates while leaving behind improved surface finishes.

The Multi Flute tools from Niagara Cutter include the S638, S738 and S938 series and complements the S545 series. With these latest additions, the Multi Flute family is now more versatile and easier to use than ever for a wide range of applications.
