Iscar 6003654 Cutoff Insert TAGN3UT IC808 3mm Carbide

Product Description

The ISCAR 6003654 is a solid carbide cutoff and grooving insert in the Tang-Grip series, designed for parting and grooving operations on CNC lathes and turning centers. It carries the TAGN3UT geometry with a chipbreaker designation of UT and is manufactured in the IC808 grade, a PVD-coated submicron carbide grade suited for a broad range of workpiece materials. The cutting width is 3.00 mm (0.1180 inches), the corner radius is 0.30 mm (0.0118 inches), and the relief angle is 7 degrees. The insert is single-ended with a neutral lead angle and is held by a clamp-style toolholder compatible with the Tang-Grip system.

This insert is intended for grooving and parting applications across universal workpiece materials, covering ISO material groups H, K, M, P, and S. That breadth makes it a practical stock item for shops running mixed-material turning work in both production and job-shop environments. The IC808 PVD coating provides wear resistance and edge integrity at moderate to high cutting speeds. Licensed machinists, CNC operators, and toolroom technicians working in general turning applications will find this insert a direct fit for Tang-Grip compatible toolholders already in use on the machine.

Key Features

• IC808 PVD-coated submicron carbide grade for consistent performance across ISO H, K, M, P, and S workpiece materials
• 3.00 mm cutting width (0.1180 inches) for standard parting and grooving slots
• TAGN3UT geometry with UT chipbreaker for controlled chip formation during cutoff operations
• Neutral lead angle and 7-degree relief angle for balanced cutting forces
• 0.30 mm corner radius minimizes stress concentration at groove base
• Tang-Grip clamping system provides rigid, repeatable insert seating without set screws

Compatibility

Designed as a direct-fit replacement for Tang-Grip series clamp-style toolholders accepting TAGN3 inserts. Conforms to ISO 13399 tooling data standards. Verify toolholder seat dimensions before installation.

Installation Notes

This insert is installed and indexed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use a proper insert seating tool or Tang-Grip key to seat the insert fully into the pocket before clamping. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert geometry.
