    New TANG GRIP Inserts for High Feed Machining


    Highlights
    ISCAR is launching new TANG-GRIP TAG.. HF
    inserts for High Feed machining.

    TAG...HF new TANG-GRIP inserts designed for high feed parting and grooving operations
    The new TAG-HF inserts are suitable for machining at extremely high feeds. They provide a significant increase in productivity when compared with other parting inserts existing in the market today.
    The inserts are available in .118, .157 and .197” width.

    Features
    • Reinforced cutting edge and bigger corner radius designed for extremely high feeds
    • Can improve productivity by up to 300%
    • Can be used on all standard tools
    • Most recommended for use on 1.378 and 1.772” blades, integral shank tools, and reinforced blades

    The recommendations in the table below are for the maximum workpiece diameters that can be machined by each tool type and insert width when applying high feed.

    Insert width Maximum bar diameter
    .118” .157” .197”
    Blade TGFH 32- Ø1.97 Ø2.36 Ø2.76
    Blade TGSU 35- Ø2.36 Ø2.76 Ø3.15
    Blade TGFH 45- Ø2.76 Ø3.15 Ø3.54
