Hertel 8000175 Carbide Shim Indexable External Turning

Product Description

The HERTEL 8000175 is a carbide shim designed for indexable tooling systems used in external turning applications. It supports triangular insert shapes with a negative rake and neutral cutting direction, conforming to the ITSN shim style. At 0.1875 inches thick and sized for a 1/2-inch (0.5000 inch decimal) inscribed circle, this shim seats and protects the pocket of an indexable tool holder, maintaining precise insert positioning and extending holder life. Installation is performed by qualified machinists or toolroom technicians during insert changes or holder setup. Weighing 0.02 pounds, it is a lightweight but critical component in maintaining cutting geometry and surface finish consistency.

This shim is intended for external turning operations on CNC lathes and manual turning centers where indexable carbide inserts are used. It is specified for use where a negative, neutral-cutting triangular insert is mounted in a compatible holder. The HERTEL 8000175 is suited for production and job-shop environments requiring consistent insert seating and repeatable tool geometry across multiple insert changes.

Key Features

• ITSN shim style for negative rake, neutral cutting direction triangular inserts
• Carbide construction resists wear and deformation under cutting forces
• 1/2-inch inscribed circle (12.70 mm) sizing matches standard triangular indexable inserts
• 0.1875-inch thickness provides proper insert height and pocket protection
• Compatible with tool holder A16RPTFNR11
• Lightweight at 0.02 pounds for minimal holder mass impact

Compatibility

Confirmed compatible with tool holder A16RPTFNR11. Designed for use with triangular indexable inserts with a 1/2-inch inscribed circle in external turning holders requiring the ITSN shim style.

Installation Notes

Installation is performed by machinists or toolroom technicians during routine insert indexing or holder maintenance. Power down and lock out the machine spindle before accessing the tool holder pocket. Ensure the shim seats fully and flat in the pocket before torquing the insert clamp per the holder manufacturer specifications. Inspect the shim for cracking or wear at each insert change and replace if damage is present.
