Iscar 7090221 Cl Clamp Isoturn Indexable Toolholders

Product Description

The ISCAR 7090221 is a CL-style clamp designed for use with Isoturn series indexable turning toolholders. It secures indexable inserts firmly in place during turning operations, maintaining precise insert positioning and resisting cutting forces. This clamp is a direct replacement component intended for field servicing of existing toolholder assemblies. At 0.02 pounds, it is a small but critical hardware item that keeps insert clamping consistent across the toolholder body. Licensed machinists and CNC lathe operators performing routine insert changes or toolholder refurbishment are the primary installers of this part.

This clamp is suited for use in CNC and manual turning applications where Isoturn series toolholders are already in service. It supports right-hand and left-hand cut configurations depending on the compatible toolholder selected. Typical install scenarios include production floor insert changes, toolholder rebuild kits, and preventive maintenance restocking. It fits a range of MDJN and related style toolholders within the Isoturn product family.

Installation Notes

Installation is performed by a machinist or toolroom technician during scheduled insert changes or toolholder maintenance. Ensure the machine spindle is fully stopped and the toolholder is removed from the turret before disassembling the clamp. Use the appropriate torx or clamp screw driver as specified for the toolholder model. Do not overtighten the clamp screw, as improper torque can damage the insert seat or clamp body.
