Iscar 6003447 Cutoff Insert 3mm IC908 Carbide Tang-grip

Product Description

The ISCAR 6003447 is a solid carbide cutoff and parting insert in the Tang-Grip series, designed for single-end use in precision parting and grooving operations. It carries the TAGR3J6D designation and is manufactured in grade IC908 with a PVD coating for extended tool life in demanding cuts. The insert features a 3.00 mm (0.1180 inch) cutting width, a 6-degree right-hand lead angle, a 7-degree relief angle, and a corner radius of 0.20 mm (0.0079 inch). It is held in the toolholder via a clamp-style Tang-Grip interface. Licensed machinists and CNC operators working in production turning environments are the primary users of this insert.

This insert is suited for parting applications across a broad range of workpiece materials. The IC908 grade with PVD coating and Universal primary workpiece material designation covers steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, corresponding to ISO material codes H, K, M, P, and S. It fits standard Tang-Grip toolholders that accept the TAGR style insert geometry. The J chipbreaker profile is designed for controlled chip formation during parting and cutoff operations at moderate feeds and depths.

Key Features

• IC908 grade PVD-coated solid carbide construction for wear resistance across multiple material groups
• 3.00 mm cutting width with 0.20 mm corner radius for clean parting grooves
• 6-degree right-hand lead angle with 7-degree relief angle for controlled chip clearance
• J chipbreaker for reliable chip control during cutoff operations
• Tang-Grip clamp-style holding interface for rigid insert seating and repeatability
• Single-end insert; not a multi-use reversible geometry

Compatibility

Designed for use with Tang-Grip series toolholders accepting TAGR style inserts. Compatible workpiece material codes include H, K, M, P, and S per ISO material classification. Material grades C1, C2, C6, and C7 are applicable. Conforms to ISO 13399 standards.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all power is isolated before seating or removing inserts from the Tang-Grip toolholder. Verify the clamp and pocket are clean and free of chips before inserting to ensure proper seating and prevent insert rocking. Do not exceed the toolholder manufacturer's recommended feed and speed parameters for the IC908 grade and selected workpiece material.
