Hertel 8000186 Carbide Shim Indexable Turning 1/2 in

Product Description

The HERTEL 8000186 is a carbide shim designed for indexable external turning toolholders. It seats beneath the insert to provide a stable, repeatable seating surface and protect the toolholder pocket from damage during cutting. The SM shim style suits negative-rake, neutral cutting-direction inserts with a cylindrical compatible insert shape. At 0.125 inches thick and sized for a 1/2-inch inscribed circle, this shim restores proper insert height and prolongs toolholder pocket life in high-volume turning operations. Installation is straightforward, and replacement is a routine part of insert-change maintenance for production turning setups.

This shim is intended for external turning applications on CNC lathes and manual turning centers where indexable carbide inserts are used. It is suited to both production shops and toolroom environments running negative-rake insert geometries. The 1/2-inch inscribed circle dimension matches common insert sizes used in medium to heavy stock-removal turning. Confirmed compatible toolholder: A16RPTFNR11. Sold individually; minimum order quantity is 5 pieces per order.

• Cylindrical compatible insert shape with 1/2-inch (0.5000 inch) inscribed circle
• 0.125-inch thickness provides consistent insert seating height
• Direct replacement shim for confirmed compatible toolholder A16RPTFNR11
• Lightweight at 0.01 pounds — easy to stock in quantity for insert-change intervals

Compatibility

Confirmed compatible with toolholder A16RPTFNR11. Designed for use with cylindrical indexable inserts featuring a 1/2-inch inscribed circle in external turning applications using negative-rake, neutral cutting-direction insert geometries.

Installation Notes

Installation is performed by machining technicians or toolroom personnel during insert changes or toolholder pocket maintenance. Power down and lock out the machine spindle before accessing the toolholder. Seat the shim flat in the pocket before placing the insert; verify the pocket and shim surfaces are clean and free of chips. Follow the toolholder manufacturer torque guidance for the clamp or insert screw — do not overtighten, as this can crack the carbide shim.
