Iscar 6002643 Cutoff Insert 4.1mm Right Hand Self-grip

Product Description

The ISCAR 6002643 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the GTR-4-4D profile with an IC354 PVD-coated grade, delivering a 4.10 mm cutting width suitable for precise cut-off work in steel and hard materials. The insert seats into ISCAR Self-Grip toolholders using a clamp-style holding method. A 4-degree right-hand lead angle and a 7-degree relief angle combine to control chip flow and reduce cutting forces. The 0.24 mm corner radius supports clean surface finishes at the parting face. This insert is intended for use by machinists and toolroom technicians working in production or job-shop turning environments.

The 6002643 is suited for cut-off and grooving applications on ferrous and non-ferrous workpieces in both light and moderate production runs. It fits ISCAR Self-Grip holders sized for a size-4 insert seat, making it a direct component in standard ISCAR GTR tooling setups. The IC354 grade with PVD coating is selected for its wear resistance in interrupted cuts and in materials classified under C5 and C6 material grade ranges. This is a single-end insert, meaning it is indexed once and replaced when worn.

Key Features

• 4.10 mm cutting width for consistent parting groove dimensions
• IC354 PVD-coated solid carbide grade rated for C5 and C6 material groups
• 4-degree right-hand lead angle with 7-degree relief angle for controlled chip evacuation
• 0.24 mm corner radius for clean parting face finish
• Clamp-style insert holding method in ISCAR Self-Grip size-4 seat
• Single-end design; replace when cutting edge is worn

Compatibility

Designed for use with ISCAR Self-Grip toolholders accepting a size-4 insert seat in the GTR series. Verify holder designation against ISCAR tooling catalogs to confirm fitment before ordering.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before seating or replacing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating. Confirm the clamp torque specification from the ISCAR holder documentation, as insert seating force requirements vary by holder model.
