Iscar 6011376 DGN4003C IC808 Carbide Cutoff Insert 4mm

Product Description

The ISCAR 6011376 is a solid carbide cutoff and grooving insert in the Do-Grip series, designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the DGN4003C designation with an IC808 manufacturer grade and a PVD coating applied to a submicron carbide substrate. The insert delivers a 4.00 mm cutting width (0.1575 inches) with a neutral lead angle and neutral hand orientation, making it suitable for straight-in parting cuts. A chipbreaker geometry designation of C supports controlled chip evacuation in a wide range of materials. The double-ended design extends usable life per insert.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S — meaning it handles steel, stainless steel, cast iron, non-ferrous materials, and heat-resistant superalloys within appropriate cutting parameters. It is used in production turning environments for grooving, parting, and cutoff applications where consistent width and chip control are critical. The clamp-style insert holding method seats the insert securely in compatible Do-Grip toolholders. This insert is sold individually and is subject to a minimum order quantity of 10 pieces per order.

Key Features

• Neutral lead angle and neutral hand — compatible with straight-in cutoff operations
• Double-ended insert geometry extends tool life per piece
• C chipbreaker for controlled chip formation across a wide material range
• Conforms to ISO 13399 cutting tool data representation standards

Compatibility

Designed for use with Do-Grip series clamp-style toolholders that accept DGN insert size code 4003 with an insert seat size of 3. Compatible with ISO material groups H, K, M, P, and S as indicated by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be stopped and all axis motion halted before changing inserts. Seat the insert fully into the Do-Grip toolholder pocket and confirm the clamp is torqued per the toolholder manufacturer specifications before initiating a cut. Inspect the insert seat for chips or debris before seating a new insert to ensure proper support and prevent premature edge failure.
