Iscar 6099246 Carbide Cutoff Insert 4.1 Mm Left Hand

Product Description

The ISCAR 6099246 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the GFL 4-4D catalog designation and uses ISCAR's Self-Grip clamping system, which holds the insert securely under cutting loads without additional fasteners. The IC354 grade combines a PVD coating with a C5/C6 carbide substrate, making it well-suited for cutting stainless steel and general steel workpieces. Cutting width is 4.10 mm (0.1614 inches), and the insert features a 4-degree left-hand lead angle with a 7-degree relief angle. This is a single-end insert sold individually, with a minimum order quantity of 10 units.

This insert is intended for metal-cutting applications where clean, accurate parting cuts are required. The left-hand lead angle and 0.24 mm corner radius make it appropriate for light-to-medium stock removal on stainless steel and steel components. Typical use cases include production turning shops, tool-and-die operations, and maintenance machining environments where consistent cut-off quality is a priority. The IC354 grade's PVD coating extends edge life when cutting work-hardening materials such as 304 and 316 stainless steel.

Key Features

• Solid carbide construction with IC354 PVD-coated grade for extended wear resistance on stainless and steel
• 4.10 mm (0.1614 inch) cutting width for consistent parting groove dimensions
• Left-hand, 4-degree lead angle with 7-degree relief angle reduces cutting forces and chip interference
• Self-Grip clamping system secures the insert mechanically without set screws
• 0.24 mm corner radius minimizes stress concentration at the cut-off groove root
• Meets ISO 13399 tooling data standards for integration with CAM and tool management systems

Compatibility

Designed for use with ISCAR Self-Grip GFL series cut-off toolholders accepting size 4 inserts. Consult the ISCAR GFL toolholder lineup to confirm correct pocket and clamping jaw fit before ordering.

Installation Notes

Installation and replacement should be performed by a qualified machinist or toolroom technician with the machine in a locked-out, de-energized state. Verify that the toolholder pocket and clamping jaw are clean and free of chips before seating the insert. Do not use the insert in a holder with a worn or damaged clamping jaw, as insert retention and dimensional accuracy will be compromised. Follow the machine tool builder's recommended feed and speed parameters for the workpiece material and insert grade.
