Iscar 6404180 Grooving Insert TAGB1208Y IC808 Sumo-grip

Product Description

The ISCAR 6404180 is a single-end grooving insert carrying the TAGB1208Y designation and IC808 manufacturer grade. It is manufactured from solid carbide and features a PVD-applied multi-layer coating of AlTiN, TiAlN, and TiN for thermal resistance and wear performance. The insert delivers a 12 mm cutting width with a maximum depth of cut of 8.4 mm and a 0.80 mm corner radius. It belongs to the Sumo-Grip series and uses a clamp holding method. Machinists and CNC turning center operators install this insert for external and internal grooving operations across a wide range of workpiece materials.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range spans hardened steels, cast irons, general steels, stainless steels, and high-temperature alloys, making it suitable for production turning environments handling mixed-material runs. The Sumo-Grip series is designed for rigid clamping in matching ISCAR Sumo-Grip toolholders. It is a multi-use insert appropriate for grooving, parting, and face grooving applications where consistent depth control and edge stability are required.

Key Features

• Solid carbide substrate with PVD coating process for controlled edge sharpness and coating adhesion
• Multi-layer AlTiN, TiAlN, and TiN finish for heat resistance and extended tool life across varied materials
• 12 mm cutting width with 8.4 mm maximum depth of cut and 0.80 mm corner radius
• Positive rake geometry reduces cutting forces and improves chip flow
• Y-style chip breaker promotes chip control during deep grooving passes
• Single-end design with clamp holding method for secure, repeatable seating in Sumo-Grip toolholders

Compatibility

Designed for use in ISCAR Sumo-Grip series grooving toolholders that accept TAGB-style inserts with a 1208 insert size designation. Compatible workpiece material groups per ISO 13399 classification: H, K, M, P, and S.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate ISCAR Sumo-Grip clamp and torque key as specified by the toolholder documentation — do not substitute fasteners. Inspect the insert pocket and clamp for chips or debris before seating to ensure proper clamping force and insert stability.
