Hertel 8000163 Indexable Shim 3/8 Inch External Turning

Product Description

The HERTEL 8000163 is a carbide shim designed for indexable tooling systems used in external turning applications. Measuring 0.125 inches thick with a 3/8-inch (0.375-inch) inscribed circle, this IDSN-style shim seats between the tool holder pocket and the indexable insert to maintain precise cutting geometry. It is configured for negative rake and neutral cutting direction, making it compatible with standard negative-geometry insert seating. Machinists and tooling technicians install this shim during insert changes or holder refurbishment to restore correct insert positioning and protect the tool holder pocket from wear damage.

This shim is intended for external turning operations on CNC lathes and manual turning centers where indexable carbide inserts are used. It is rated for use with diamond-shaped inserts and is designed to fit the A16RPTFNR11 tool holder. It suits applications where maintaining consistent insert height and rake geometry is critical to surface finish and dimensional accuracy in production turning environments.

Key Features

• IDSN shim style for negative rake, neutral cutting direction indexable insert systems
• 3/8-inch inscribed circle diameter matches standard diamond insert sizing
• 0.125-inch thickness for precise insert pocket seating
• Carbide construction resists deformation under cutting loads and insert clamping pressure
• Compatible with A16RPTFNR11 complete tool holder
• Protects tool holder pocket from direct insert contact, extending holder service life

Compatibility

Designed for use with diamond-shaped indexable inserts in external turning holders. Confirmed compatible with tool holder A16RPTFNR11. Intended for negative rake, neutral cutting direction insert configurations.

Installation Notes

Installation is performed by qualified machinists or tooling technicians during insert indexing or holder maintenance. Remove the insert and clamp screw before seating or replacing the shim, and inspect the pocket for debris or damage prior to installation. Ensure the shim sits fully flat in the pocket before torquing the clamp screw to the tool holder manufacturer specification. Do not reuse shims that show signs of cracking, deformation, or pocket-contact wear.
