Product Description

The HERTEL 8000177 is a carbide shim designed for use with indexable cutting inserts in external turning applications. Shims of this type seat beneath the insert in a tool holder pocket, providing a hardened bearing surface that protects the holder body from cutting forces and chip impact. This shim follows the IVSN style and is configured for diamond-shaped inserts with a negative rake and neutral cutting direction. It measures 0.125 inches thick and is sized for inserts with a 3/8 inch inscribed circle. Installation is performed by qualified machinists and toolroom technicians during insert changes or holder reconditioning.

This shim is suited for external turning operations on CNC lathes and manual turning centers where diamond-shaped indexable inserts are used. It is specified for use with the A16RPTFNR11 complete tool holder. The IVSN shim style and negative rake configuration make it appropriate for general-purpose external turning on a range of workpiece materials. Sold individually with a minimum order quantity of 5 units.
