Iscar 6400739 Grooving Insert GIP398199P IC20 Carbide

Product Description

The ISCAR 6400739 is a solid carbide, uncoated grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. Carrying the IC20 grade designation, this neutral-hand insert features a 3.98 mm (0.1567 inches) cutting width and a full radius corner geometry at 1.99 mm, delivering consistent, repeatable cuts. The positive rake angle of 7 degrees reduces cutting forces and supports smooth chip flow. With a double-ended design and clamp-style holding method, it offers extended tool life and efficient use per insert. This insert is installed and managed by machinists and CNC turning specialists working in production and job-shop environments.

The ISCAR 6400739 is suited for grooving and cutoff applications across a wide range of workpiece materials. The IC20 uncoated carbide grade and universal primary workpiece material classification cover steel, cast iron, stainless, non-ferrous metals, and high-temperature alloys. The P chip breaker geometry supports controlled chip formation during interrupted and continuous grooving passes. Maximum depth of cut is 11.80 mm (0.4646 inches), placing it within the Cut-Grip series range of 10.00 mm to 20.00 mm max depth capacity. The insert style code is GIP with size code 398199, overall length 15.30 mm (0.6024 inches).

Key Features

• Solid carbide IC20 grade, uncoated — suitable for dry or light-coolant grooving operations
• Neutral hand orientation with double-end design for extended insert utilization
• Full corner radius of 1.99 mm for smooth groove floor finish
• Positive 7-degree rake angle reduces cutting forces and improves chip evacuation
• P chip breaker for controlled chip formation across universal workpiece materials
• Clamp-style insert holding for secure, repeatable seating in Cut-Grip toolholders

Compatibility

Designed for use with ISCAR Cut-Grip series clamping toolholders that accept the GIP insert style with size code 398199. Consult ISCAR toolholder documentation to confirm seat and clamp compatibility before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully in the pocket and verify clamp engagement before resuming cuts. Do not exceed the maximum depth of cut for the insert size, and inspect the cutting edge and seating pocket for wear or debris at each insert change.
