Seco Tools LLC has expanded its solutions for difficult-to-machine materials with the introduction of the High Feed 6—the latest addition to the High Feed series of indexable-insert milling cutters. This new cutter features a design
created specifically to boost material removal rates and handle high chip loads, resulting in substantial productivity increases and exceptional tool life, according to the company.

The High Feed 6 milling cutter shows strong performance in all kinds of steels, especially mold and die steels, making it particularly valuable to that industry segment. In addition, the new tool can tackle a variety of difficult-to-machine materials from stainless steel to heat-resistant superalloys. The tool performs equally well in all high-feed applications, including facemilling, slotting, contouring, plunging and helical interpolation. The large-diameter cutter bodies are capable of 0.070" (1.8 mm) axial depths of cut and feature double-sided inserts with six cutting edges for effective material removal and low operating costs.

High Feed 6 inserts mount at low lead angles to direct machining forces up into the machine tool spindle rather than radially against the side of the tool. As such, the tool experiences less vibration and provides long, predictable performance. The flexible High Feed 6 is available in 13 metric cutters with outer diameters from 50 mm to 160 mm and nine imperial cutters ranging from 2 to 4 inches in diameter, as well as both normal and close-pitch versions. Inserts are available in three cutting geometries. A variety of advanced grade and coating options are available.
