Iscar 6011438 Cutoff Insert 4mm Tang-grip IC830 Carbide

Product Description

The ISCAR 6011438 is a solid carbide cutoff and parting insert designed for precision grooving and parting operations on CNC lathes and turning centers. Part of the Tang-Grip series, this single-end insert features a 4 mm cutting width (0.1575 inches) and a right-hand lead angle of 4 degrees. The IC830 grade uses a PVD coating process, making it well suited for cutting superalloys and other difficult-to-machine materials. With a relief angle of 7 degrees and a corner radius of 0.24 mm (0.0094 inches), the insert delivers controlled chip formation through its J-style chipbreaker geometry. It is installed using a clamp-style holding method and conforms to ISO 13399 standards.

This insert is intended for parting and cutoff applications where tight dimensional control and consistent chip evacuation are critical. The IC830 PVD-coated grade is optimized for superalloy workpieces, though its geometry also supports a range of ISO M and ISO S material groups. Typical installations occur in production turning environments where Tang-Grip toolholders are already in use. The J chipbreaker geometry is selected when moderate feeds and controlled chip curl are priorities. This insert is sold individually, with a minimum order quantity of 10 units.

Key Features

• 4 mm cutting width (0.1575 inches) for standard parting and grooving operations
• IC830 PVD-coated solid carbide grade optimized for superalloys (ISO M, P, S material groups)
• Tang-Grip series clamp-style holding for rigid, repeatable seating in compatible toolholders
• J-style chipbreaker geometry for controlled chip formation at moderate feed rates
• Right-hand lead angle of 4 degrees with 7-degree relief angle for positive cutting action
• Conforms to ISO 13399 insert identification standards

Compatibility

Designed as a direct-fit replacement insert for ISCAR Tang-Grip series toolholders that accept TAG-style inserts with a size code of 4. Compatible toolholder selection should confirm clamp-style retention and right-hand orientation before installation.

Installation Notes

Installation of carbide parting inserts should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing any insert. Ensure the Tang-Grip toolholder pocket and clamping surfaces are clean and free of chips or debris before seating the insert. Do not exceed the feed and speed parameters specified by the toolholder manufacturer for the IC830 grade and workpiece material combination.
