Seco recently expanded its line of Square 6 shoulder milling cutters with the development of smaller tool diameters. The new sizes allow an even greater range of applications to benefit from this popular lineup of cutters that balances economy and performance. Like its larger counterparts, the new Square 6 -04 effectively tackles a wide range of materials, operations and machining conditions, but from cutting diameters that range from 0.75” to 2.5”, with a maximum cutting depth of 0.157”. Square 6 -04 is a reliable, cost-effective, first-choice solution for all general machining requirements, including square shoulder milling, face milling, slotting, plunging and slotting by plunging. Ideal for small and medium milling machines, the Square 6 -04 offers a nickel-coated, pre-hardened cutter body, which maximizes the life of the cutter body and provides minimal insert runout.

Furthermore, with two different pitch configurations on the cutter body, the Square 6 -04 reduces vibrations, improves surface finish and increases component quality. For increased versatility, mounting types include Cylindrical, Weldon, Arbor and Combimaster. The Square 6 -04 employs trigonal inserts with six indexable cutting edges, providing high productivity and lowering cost per edge. Additionally, the ME08 geometry is available in two different corner radii and a wide range of industry-leading carbide grades. These inserts will offer high accuracy, exacting tolerances, reduced noise and maximum reliability in a variety of workpiece materials. Furthermore, the Square 6 -04 inserts can be set to a true 90º cutting angle to createclean 90º walls and eliminate secondary operations. Inserts lock into place via a strongcenter screw placed in the same direction as cutting forces, and wiper flats optimize surface finishes.
