Iscar 6002499 Carbide Cutoff Insert 4.1 Mm Self-grip

Product Description

The ISCAR 6002499 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. This insert features a GTR-4 style profile with a 4.1 mm cutting width and an 8-degree right-hand lead angle, making it suited for precision cutoff work where controlled chip flow and consistent width are required. The IC354 grade carbide substrate is applied with a PVD coating, providing a wear-resistant cutting edge for ferrous and non-ferrous workpiece materials classified under material grades C5 and C6. Installation is handled via clamp-style holding, compatible with the Self-Grip toolholder series.

This insert is intended for metal-cutting applications in machining environments, including production turning on manual and CNC equipment. The right-hand lead angle and 7-degree relief angle support smooth entry and reduce lateral cutting forces during cutoff passes. The 0.24 mm corner radius helps manage surface finish at the part-off point. Machinists working in job shops, production facilities, or tool rooms will find this insert applicable to standard parting operations on bar stock and turned components.

Key Features

• GTR-4 insert style with 4.1 mm (0.1614 inch) cutting width for precise parting operations
• IC354 grade carbide with PVD coating for extended tool life on C5 and C6 material grades
• 8-degree right-hand lead angle reduces burr formation and improves chip control
• 7-degree relief angle minimizes rubbing and supports clean cutoff geometry
• 0.24 mm corner radius for consistent finish at the parting line
• Clamp-style holding method for secure, repeatable seating in Self-Grip toolholders

Compatibility

Designed for use with ISCAR Self-Grip series toolholders that accept insert seat size 4. Confirm toolholder compatibility with insert size code 4 and clamp-style holding before installation.

Installation Notes

This insert is installed and replaced by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the holder pocket and verify clamp engagement before resuming cutting operations. Follow the toolholder manufacturer guidelines for clamp torque and insert indexing procedure.
