Seco recently added a new helical tool to its Square T4-08 line of square shoulder mills that feature four cutting edges and an innovative tangential cutter design. Ideal for slotting and contouring/shouldering applications, the Square T4-08 Helical excels in machining challenging materials such as cast iron, steel, and stainless steels.
Like other products within the line, the SquareT4-08 Helical's strong, reliable pocket seats combined with multi-edge inserts optimize cutting stability and allow for clean 90-degree walls. The inserts mount tangentially in the cutter so that the cutting forces impact the thickest parts of the inserts, allowing manufacturers to achieve the required levels of strength for increased depths of cut with small diameters.
In addition to its high metal removal rates, users will also benefit from the Square T4-08 Helical's versatility, with options that include normal and close pitch variations, M08 and MD08 insert geometries, and MP3000, MK2050 and F40M grades. Various mounting types include Seco-Capto™, Weldon, Arbor and Combimaster™.
The tool has cutting diameters that range from 0.98" (25 mm) to 2.13" (54 mm) and depths of cut between 0.87" (22 mm) and 2.52" (64 mm). Corner radii ranges from 0.02" (0.4 mm) to 0.063" (1.6 mm). Furthermore, the entire Square T4-08 Helical range has integrated through-coolant channels to provide extended tool life.
