Seco Tools’ Engineered Solutions Square T4-12 line of square-shoulder and helical milling cutters features larger insert sizes and enables manufacturers to achieve increased depths of cut and higher metal-removal rates when roughing and semi-finishing steel, cast iron and other workpiece materials. The inserts are equipped with four curved cutting edges that are designed to lower tooling cost-per-part and ensure smooth machining operations. They mount tangentially in the cutter bodies to increase performance stability and ease access to their mounting screws. This mounting design directs cutting forces to the thickest part of the inserts, which is said to contribute to their higher metal-removal capability.

Cutter diameters for the square-shoulder inserts range from 1" to 5" (25 to 125 mm), with corner radii as large as 0.125" (3.1 mm). Diameters for the helical inserts range from 2" to 4" (50 to 100 mm), with corner radii as large as 0.125" (3.1 mm). The inserts are also available in a wide selection of grades and geometries as well as in normal and close-pitch versions, the company says.

Seco will also display the Highfeed 6 milling cutter, Niagra Stabilzer 2.0 end mill, PCBN insert series, and TK1501 and TK0501 grades.
