Iscar 6099366 Carbide Cutoff Insert 3.1mm Right Hand

Product Description

The ISCAR 6099366 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to the IC354 grade with a PVD coating, this single-end insert delivers consistent performance in C5 and C6 material grade applications. It features a 3.10 mm cutting width, a right-hand lead angle of 4 degrees, and a 7-degree relief angle. The insert seats into a clamp-style holder using the Self-Grip holding method, making tool changes straightforward for machinists working in production environments.

This insert is suited for cut-off and parting applications on ferrous and non-ferrous workpieces in both job shop and production turning environments. The GTR insert style combined with IC354 PVD coating supports performance in medium-to-high cutting speed conditions. It is installed by licensed machinists and CNC operators who require a reliable, repeatable parting solution with controlled chip formation. The Self-Grip series is recognized for secure clamping without the need for additional locking hardware.

Key Features

• IC354 grade carbide with PVD coating for extended wear resistance
• 3.10 mm cutting width for precise parting and grooving
• Right-hand lead angle of 4 degrees for directional chip control
• 7-degree relief angle reduces rubbing and tool pressure
• 0.20 mm corner radius minimizes stress concentration at the cutting edge
• Single-end insert design in the Self-Grip clamping series

Compatibility

Designed as an OEM-style replacement or direct-use insert for Self-Grip series clamp-style cutoff and grooving toolholders that accept insert seat size 3.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and all axes locked before changing inserts. Seat the insert fully into the Self-Grip holder and confirm the clamp is secure before resuming operation. Inspect the insert seat for chips or debris that could affect seating accuracy. Follow the toolholder manufacturer guidelines for proper torque and clamping procedure.
