Iscar 6004537 Carbide Cutoff Insert 0.250 in Grooving

Product Description

The ISCAR 6004537 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the TAGN6.3JT designation and is manufactured to the IC908 grade, a PVD-coated submicron carbide grade engineered for consistent performance across a wide range of workpiece materials. The insert features a 0.250-inch (6.35 mm) cutting width, a neutral lead angle, a 7-degree relief angle, and a 0.0134-inch (0.34 mm) corner radius. The JT chipbreaker geometry promotes efficient chip control during grooving and parting passes.

This insert is suited for grooving and parting applications in both production and job-shop turning environments. The IC908 grade with PVD coating is rated for universal workpiece material compatibility, covering steel, stainless steel, cast iron, high-temperature alloys, and non-ferrous materials — corresponding to ISO material groups P, M, K, S, and H. It fits the Tang-Grip insert holding system, which uses a clamping method for secure, repeatable seating in compatible Tang-Grip toolholders.

Key Features

Compatibility

Designed for use with Tang-Grip series toolholders that accept TAG-style inserts with a 6.3 size code. Compatible with ISO material groups P, M, K, S, and H as designated by the IC908 grade.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the Tang-Grip pocket and verify the clamp is properly engaged before resuming cuts. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for the 6.35 mm insert width.
