ISCAR's new Penta 17 line now for Swiss and Miniature Machining

Iscar's latest addition in the PENTA series introduces a new 5-cornered insert for machining miniature parts. The unique shape and design of the insert rekindles this legacy insert by opening new frontiers for additional applications. Standard inserts now available in a wide range of widths from 0.010" – 0.125", with different edge configurations for parting, grooving, back-turning, side-turning, profiling and threading. The insert and toolholders enable the machining of miniature parts with right and left capabilities next to the shoulder of the workpiece. In addition to shouldering capabilities, the tool features a short head, suitable for smaller Swiss and miniature machines. Just like the Penta 24 and Penta 34 before, the Penta 17 design allows for access of the screw for indexing the insert from either side of the toolholder. The chip deflector is ideal for accurate machining and provides excellent repeatability.

Related Glossary Terms

  • grooving


    Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

  • parting


    When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.

  • profiling


    Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.

  • threading


    Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.

  • toolholder


    Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
