Scientific Cutting Tools Inc. announces a new line of high-performance helical chamfer mills. The helical cutters are significantly freer cutting and impart a smoother finish than the standard straight-flute alternatives. The variable-helical flute design provides high sheer, reduced side cutting pressure and improved chip evacuation, thus achieving extremely high performance.

Made from premium submicron carbide, the tools are manufactured in both 3-flute and 5-flute versions to address a wide variety of materials. The 3-flute design is ideal for softer materials while the 5-flute design performs well in harder materials.

Helical chamfer mills are made on CNC tool and cutter grinders to exacting tolerances. Sizes range from 1/8" to ¾" cutter diameters, and come in 60, 90 and 120 degree included angle configurations. The front of the tool is ground flat and the tip diameter is held to + or – 0.002 inch tolerance to provide ease of set up and accuracy in programming.

In addition, the small tip diameters allow for maximum machining flexibility. These high-performance cutters are stocked and ready to ship with either a bright finish or an AlTiN coating. AlTiN coating is highly recommended for steel applications, to achieve high cutting speeds and to extend tool life.
