Hertel 8000183 Carbide Shim 3/8 Inch Inscribed Circle Sktp

Product Description

The HERTEL 8000183 is a carbide shim designed for indexable tooling systems used in external turning applications. This SKTP-style shim seats between the tool holder pocket and the indexable insert, maintaining precise insert positioning and protecting the holder from wear and cutting forces. At 0.125 inches thick and sized for a 3/8 inch inscribed circle, it is compatible with triangular inserts and supports negative rake, neutral cutting direction setups. Machining shops and tool-room technicians install this shim as a replacement component when holder pockets show wear or when insert seating becomes inconsistent.

This shim is intended for external turning operations on lathes and turning centers where triangular indexable inserts with a 3/8 inch inscribed circle are in use. It is configured for negative rake geometry with neutral cutting direction, making it appropriate for general-purpose and roughing external turning passes. The listed compatible tool holder is the A16RPTFNR11. Always verify shim style and inscribed circle size against the existing holder specification before ordering.

Compatibility

Compatible with tool holder A16RPTFNR11. Designed for use with triangular indexable inserts with a 3/8 inch inscribed circle in SKTP-style pocket configurations for external turning.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during indexable insert changes or tool holder maintenance. Power down and lock out the machine before servicing any tooling components. Ensure the shim seating pocket is clean and free of chips or debris before placing the shim, as contamination will affect insert height and cutting geometry. Do not reuse a shim that shows deformation, cracking, or uneven seating surfaces.
