Iscar 7000091 Indexable Turning Tool Pin Isoturn

Product Description

The ISCAR 7000091 is a replacement pin designed for use with indexable turning toolholders in the Isoturn series. This pin features a 1/4-28 thread and measures 0.5236 inches overall length, making it a precision hardware component for securing insert clamps within boring and turning tool assemblies. It is installed by machinists and tooling technicians during toolholder maintenance or insert changeover. The part is compatible with CL 20 clamps and a wide range of CNMA, CNMG, and CNGA insert styles commonly used in production turning operations.

This pin is intended for use in indexable boring toolholder assemblies that conform to the Isoturn series and A-MCLN toolholder style. It fits within the CL 20 clamp hardware system and supports a broad selection of CN-style inserts across multiple chipbreaker geometries. Typical applications include CNC and manual turning centers where insert clamps require periodic hardware replacement. The part carries an industry standard number of NL44, which can aid cross-referencing with equivalent hardware from other sources.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before replacing toolholder hardware, ensure the machine is fully powered down, the spindle is locked, and the workholding area is clear. Use the correct driver size for the 1/4-28 thread to avoid stripping. Do not overtighten, as this can damage the clamp seating surface or distort the insert pocket.
