Iscar 6003399 DGN3102J IC907 Carbide Cutoff Insert 3.1mm

Product Description

The ISCAR 6003399 is a solid carbide double-ended cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Carrying manufacturer grade IC907 with a PVD coating, this insert delivers wear resistance across a wide range of workpiece materials. The cutting width measures 3.1 mm (0.122 inches) with a 0-degree lead angle and a neutral hand orientation. A 0.20 mm corner radius and 7-degree relief angle contribute to clean entry and controlled chip evacuation. It belongs to ISCAR Do-Grip series and uses a clamp-style insert holding method for secure, repeatable seating in compatible toolholders.

This insert is suited for grooving and parting applications in both production and job-shop turning environments. The IC907 submicron carbide grade with PVD coating is rated for universal primary workpiece materials, covering ISO material groups H, K, M, N, P, and S. That broad material compatibility makes it a practical stock item for shops running mixed-material workloads including steel, stainless, cast iron, non-ferrous, and high-temperature alloys. The J chipbreaker geometry is matched to moderate feed and depth-of-cut conditions typical in cutoff and grooving work. Maximum depth of cut reaches 18.00 mm (0.709 inches).

Compatibility

Designed for use in ISCAR Do-Grip series clamping toolholders that accept DGN insert style with seat size 2. Compatible across ISO material groups H, K, M, N, P, and S as designated by the manufacturer.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct clamping screw torque specified by the toolholder manufacturer — do not use hand tools that may over-torque the clamp. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper support and accurate cutting-edge position.
