Iscar 7001979 Clamp Screw Indexable Toolholders

Product Description

The ISCAR 7001979 is a replacement clamp screw designed for use with indexable cutting tool assemblies. Clamp screws are the fastening hardware that secures indexable inserts or clamps within a toolholder body, maintaining precise insert positioning during turning, milling, or boring operations. This screw is a direct service part intended for machinists and toolroom technicians who need to replace worn or damaged clamping hardware without replacing the entire toolholder. At 0.05 pounds, it is a lightweight but critical component in maintaining cutting tool integrity and repeatability at the machine.

This clamp screw is used in CNC and manual machining environments wherever ISCAR-compatible indexable toolholders are in service. It is appropriate for production machine shops, toolrooms, and maintenance environments running turning centers, machining centers, or boring setups that rely on indexable insert clamping systems. Keeping spare clamp screws on hand reduces unplanned downtime when hardware is lost or stripped during insert changes.

Key Features

• Direct replacement clamp screw for indexable toolholder clamping systems
• Compatible with clamp-style insert retention hardware
• Lightweight at 0.05 pounds for easy handling during insert change-outs
• Sold individually, allowing targeted hardware replacement without excess inventory
• Supports fast turnaround on insert indexing and toolholder servicing

Compatibility

Designed as a replacement clamp screw for use with ISCAR-compatible indexable toolholder clamp assemblies. Verify the specific toolholder model and clamp type before ordering to confirm fitment.

Installation Notes

Clamp screw replacement is typically performed by a machinist or toolroom technician during routine insert indexing or toolholder maintenance. Power down and lock out the machine spindle before accessing the toolholder. Use the correct torque wrench or T-key appropriate for the screw drive type to avoid stripping the head or damaging the toolholder pocket seat. Do not overtighten, as this can crack the insert or distort the clamp.
