Iscar 6004960 Carbide Cutoff Insert 4mm Neutral

Product Description

The ISCAR 6004960 is a solid carbide cutoff and grooving insert in the Tang-Grip series, designed for precision parting and slitting operations on CNC lathes and turning centers. It carries IC830 grade carbide with a PVD-applied multilayer coating of TiAlN, AlTiN, and TiN, which provides thermal resistance and edge wear protection at elevated cutting speeds. The insert features a 4mm cutting width, a neutral lead angle, a 7-degree relief angle, and a 0.25mm corner radius. It is sold individually and is well suited for machining superalloys and similar difficult-to-cut materials.

This insert is rated for slitting and cutoff applications where tight width tolerances and consistent edge geometry are required. The C chipbreaker geometry promotes chip control during deep grooving passes. A width tolerance of 0.05mm ensures repeatable groove dimensions. The neutral hand designation means the insert can be used in standard straight-blade Tang-Grip toolholders without directional restrictions, making it a flexible option for production turning environments handling superalloys and other ISO M, P, and S workpiece material groups.

Key Features

• Solid carbide construction with IC830 grade for strength and wear resistance
• PVD multilayer coating: TiAlN, AlTiN, and TiN for thermal and oxidation resistance
• 4mm cutting width with 0.05mm width tolerance for precision groove sizing
• 0.25mm corner radius and 7-degree relief angle for clean entry and reduced rubbing
• C chipbreaker geometry for controlled chip evacuation during parting operations
• Neutral lead angle and neutral hand for use in standard straight Tang-Grip toolholders

Compatibility

Designed for use with Tang-Grip series toolholders accepting TAG-style inserts with a size code 4 designation. Rated for ISO workpiece material groups M, P, and S, with primary application in superalloy cutting.

Installation Notes

Installation of cutoff inserts should be performed by a qualified machinist or toolroom technician with the machine powered down and all axis motion locked out. Seat the insert fully in the Tang-Grip pocket and verify clamping force before resuming cutting. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the IC830 grade. Inspect the insert seating pocket for chips or debris before each insert change to prevent premature edge failure.
