Iscar 6002661 GTN-4.8 Carbide Cutoff Insert IC354

Product Description

The ISCAR 6002661 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to the GTN-4.8 insert style, it features a 4.8 mm (0.1890 inch) cutting width and a neutral lead angle, making it suitable for straight plunge cutting on both OD and face grooving applications. The insert is manufactured from IC354 carbide grade with a PVD coating process, placing it in the C5/C6 material grade range for versatility across steel, stainless, and cast-iron workpieces. A 7-degree relief angle and a 0.28 mm corner radius complete the geometry. Installation uses a clamp-style holding method compatible with the Self-Grip toolholder series. Machinists and CNC operators in production turning environments are the primary users.

This insert is intended for cut-off and parting applications on turning machines where a neutral-hand, zero-lead-angle tool is required. The 4.8 mm seat size matches directly to Self-Grip series toolholders that accept GTN-4.8 inserts. It is well suited for production shops running tight-tolerance parting operations on ferrous and non-ferrous materials where controlled chip formation and consistent cut-off width are required. The coated carbide substrate handles interrupted cuts and moderate to high surface speeds. Sold individually, with a minimum order quantity of 10 units per order.

Key Features

• GTN-4.8 insert style with 4.8 mm cutting width (0.1890 inch) for precise parting and grooving
• IC354 carbide grade with PVD coating for extended tool life on ferrous workpieces
• Neutral lead angle and neutral hand for straight plunge cut-off operations
• 7-degree relief angle reduces rubbing and supports clean edge finish
• 0.28 mm corner radius (0.0110 inch) for controlled chip geometry at the cut
• Clamp-style insert holding method for secure, repeatable seating in Self-Grip toolholders
• Single-end design; replace when worn rather than index

Compatibility

Designed for use with ISCAR Self-Grip series toolholders that accept GTN-4.8 insert seat size. Consult the toolholder manufacturer specifications to confirm seat size and clamping method before ordering.

Installation Notes

Insert replacement should be performed with the machine in a full stop and all axes locked. Use the appropriate torque wrench or clamping screw driver specified by the toolholder manufacturer to seat the clamp — do not overtighten by hand. Inspect the insert pocket and clamping surfaces for chips or wear before seating a new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
