Iscar (Arlington, TX) is introducing the TANGPLUNGE, a new side plunger that is the first in a new generation of plungers. Its advantages include the ability to machine at long overhang with minimal bending forces, which results in less vibration, noise and tool deviation, as with typical cutters. The new TANGPLUNGE HTP-R-LN 16 shell plungers are available in 2.00” 4.00” diameter range and carry the HTP LNHT 1606 ER-.63” inserts. These inserts are tangentially clamped on the frontal face of the tools—creating excellent flatness. There are four cutting edges on the right-handed insert and features a positive rake face for reduced load during machining. The pocket resembles that of the TANGMILL tool, which features high durability and excellent cutting performance. There also are coolant holes for efficient edge flushing and chip evacuation while machining. In addition to plunging these tools also can be used for general face milling applications of up to 0.118” depth-of-cut. The TORMILL is designed to perform facing, plunging and undercutting using the same uniquely shaped insert. The specially designed, peripherally ground insert features a one-of-a-kind shape and clearance angle making it possible to perform a number of operations on a variety of materials. The small corner radii and balanced design of the TORMILL makes it ideal for side plunging, small corner, as well as very large overhang operations and produces no vibration. It also is possible to ramp into material using the TORMILL should that be required. These attributes make it ideal for the die and mold industry as well as other applications that require extremely long overhang. The inserts have four 80° corners and are available with 0.02”, 0.04”, and 0.06” corner radius. It is available with long cylindrical shanks, reduced shank diameters, and with Iscar’s FLEXFIT adaptation.
