Iscar 6003450 Cutoff Insert 3mm IC908 Carbide Tang-grip

Product Description

The ISCAR 6003450 is a solid carbide cutoff and parting insert in the Tang-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. This insert carries ISCAR grade IC908, a PVD-coated carbide grade engineered for universal workpiece materials including steel, stainless, cast iron, nonferrous, and high-temperature alloys. The cutting width is 3.00 mm (0.1181 inches), the lead angle is 15 degrees right hand, and the relief angle is 7.00 degrees. A 0.20 mm corner radius promotes controlled chip formation and edge stability during deep parting cuts.

This insert is suited for production turning environments where consistent, repeatable cutoff performance is required. The Tang-Grip clamping system uses a tang-style seating geometry that resists insert pullout under the tensile forces generated during parting. Typical applications include bar-fed CNC lathes running medium to high production volumes across a broad range of workpiece materials. The IC908 PVD coating contributes to edge toughness in interrupted cuts and on materials prone to built-up edge. A right-hand lead angle directs cutting forces away from the finished workpiece face.

Key Features

• IC908 PVD-coated solid carbide grade rated for universal workpiece materials (ISO material groups H, K, M, P, S)
• 3.00 mm (0.1181 inch) cutting width for precise parting and grooving
• 15-degree right-hand lead angle reduces burr formation on the parted face
• 7.00-degree relief angle provides clearance and reduces flank wear
• 0.20 mm corner radius for edge strength and surface finish consistency
• Tang-Grip series geometry resists axial pullout during deep cutoff operations
• J-style chipbreaker geometry promotes chip curl and evacuation in through-bar parting

Compatibility

Designed for use with ISCAR Tang-Grip series cutoff and grooving toolholders that accept TAG-style inserts with a 3 mm insert size code. Compatible with ISO material grade classifications C1, C2, C6, and C7. Conforms to ISO 13399 tooling data standards.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped and locked-out state. Seat the insert fully into the Tang-Grip pocket and verify secure clamping before cycling the machine. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert size. Inspect the insert edge and pocket for chips or contamination at each index.
