Iscar 6004470 Cutoff Insert 1.4 Mm Tang-grip IC830

Product Description

The ISCAR 6004470 is a Tang-Grip series carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. The insert is manufactured from solid carbide with an IC830 grade PVD coating, engineered for cutting superalloys and a broad range of metallic workpiece materials. It features a 1.4 mm cutting width (0.0550 inches), a neutral lead angle, a 7-degree relief angle, and a J-style chipbreaker geometry that promotes controlled chip formation and evacuation during cutoff work.

This insert is intended for grooving and parting applications in production turning environments, including aerospace and general metalworking shops where superalloy, steel, and stainless workpieces are common. The Tang-Grip clamping system secures the insert mechanically without the need for top clamp interference at the cutting zone. It is suited for both roughing passes and finish grooving where tight-width tolerances are required. Machinists and CNC tooling technicians are the primary installers and users of this insert.

Key Features

• 1.4 mm (0.0550 inch) cutting width for narrow grooving and parting operations
• IC830 grade PVD-coated solid carbide construction for extended tool life in superalloys
• J-style chipbreaker geometry promotes chip control and reduces cutting forces
• Neutral lead angle and 7-degree relief angle for balanced, low-vibration cutting
• 0.16 mm corner radius for controlled edge engagement
• Tang-Grip clamping method - no top clamp interference at the cutting edge
• Single-end insert; multi-use tool system compatible

Compatibility

Designed for use with ISCAR Tang-Grip series toolholders that accept TAG-style inserts with a 1.4 mm insert size code. Compatible with grooving and parting applications on superalloy, steel, and stainless workpiece materials per ISO workpiece material codes M, P, and S.

Installation Notes

Installation is performed by tooling technicians or CNC machinists. Before seating the insert, ensure the toolholder pocket is clean and free of chips or debris that could affect insert seating and cause premature edge failure. Power down and lock out the machine spindle before changing inserts. Follow the toolholder manufacturer's clamping torque guidance and verify insert seating visually before resuming cutting operations.
