Iscar 5520237 Tcx Turning Shim Diamond Insert 1/2 in

Product Description

The ISCAR 5520237 is a TCX-style shim designed for indexable turning toolholders. Shims seat between the insert and the toolholder pocket, providing a stable, repeatable seating surface that protects the pocket floor from insert wear and cutting forces. This shim is compatible with diamond-profile inserts and fits PCLNR/L-X style toolholder configurations. It supports both left-hand and right-hand cutting directions, making it a versatile service component for turning operations. Weighing approximately 0.001 pounds, it is a precision, low-profile component appropriate for CNC and manual lathe setups maintained by machinists and toolroom technicians.

This shim is used in indexable turning applications where TCX-series toolholders are deployed. It is suited for production and job-shop environments running diamond-shaped inserts on PCLNR/L-X holders. The 1/2 inch (9.52 mm) inscribed circle dimension corresponds directly to the insert size the shim is designed to support. Both left-hand and right-hand cutting setups are accommodated, reducing the need to stock separate shims for opposing tool orientations.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert indexing or holder maintenance. Ensure the toolholder pocket is clean and free of chips or debris before seating the shim. Follow the toolholder manufacturer torque sequence for the clamp or screw securing the insert over the shim. Do not reuse a shim that shows visible deformation or cracking at the seating surface.
