Square T4-08 Helical Shoulder Mill

December 01, 2014

Seco Tools LLC 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 Square T4-08 Helical's strong, reliable pocket seats combined with multiedge 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" (25mm) to 2.13" (54mm) and depths of cut between 0.87" (22mm) and 2.52" (64mm). Corner radii ranges from 0.02" (0.4mm) to 0.063" (1.6mm). Furthermore, the entire Square T4-08 Helical range has integrated through-coolant channels to provide extended tool life.

  • arbor

    arbor

    Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.

  • pitch

    pitch

    1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.

  • slotting

    slotting

    Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.

  • stainless steels

    stainless steels

    Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.
