Hertel 8000192 Carbide Shim Indexable 1/2 Inch External Turning

Product Description

The HERTEL 8000192 is a carbide shim designed for indexable tooling systems used in external turning applications. This SM-style shim seats between the insert and the tool holder pocket, providing a stable, repeatable seating surface that protects the holder body from cutting forces and wear. It is configured for negative rake, neutral cut geometry and accepts cylindrical inserts with a 1/2-inch inscribed circle. At 3/16 inch thick and weighing just 0.02 pounds, the 8000192 is a precision-ground component machined to tight dimensional tolerances. It is installed by machinists, tool-and-die technicians, and CNC turning operators who maintain indexable tooling stations in production environments.

This shim is suited for external turning operations where a cylindrical insert with a 1/2-inch (12.70 mm) inscribed circle is used. The SM shim style and negative rake configuration make it appropriate for heavy interrupted cuts or applications where rigidity and insert support are critical. It is a direct-fit replacement component for tooling systems requiring this shim geometry, and is sold individually with a minimum order quantity of 5 pieces. Typical environments include production turning cells, job shops, and maintenance toolrooms running indexable insert toolholders.

Key Features

• SM shim style designed for cylindrical insert seating in external turning holders
• Negative rake, neutral cut configuration supports aggressive or interrupted turning operations
• 1/2-inch (0.5000 inch) inscribed circle matches standard cylindrical indexable inserts
• 3/16-inch (0.1875 inch) thickness provides consistent, repeatable pocket depth
• Carbide construction resists deformation and protects the tool holder seat from insert damage
• Compatible with tool holder A16RPTFNR11 per manufacturer specifications

Compatibility

The 8000192 is specified as compatible with tool holder A16RPTFNR11. It is designed for use with cylindrical indexable inserts having a 1/2-inch inscribed circle in external turning applications.

Installation Notes

This shim is installed by qualified machinists or tooling technicians during indexable insert changeover or holder maintenance. Ensure the machine spindle is fully stopped and the tool holder is removed from the turret before servicing insert pocket components. Inspect the shim seating surface and pocket for chips or debris before installation, as contamination under the shim will affect insert runout and surface finish. Follow the tool holder manufacturer's torque specifications for the insert clamping screw.
