Iscar 6405389 Grooving Insert ING3189 IC808 Solid Carbide

Product Description

The ISCAR 6405389 is a solid carbide grooving insert designed for precision groove turning operations on CNC lathes and turning centers. Manufactured to the ING insert style in size code 3189, it carries the IC808 grade with a PVD-applied multi-layer coating of AlTiN, TiAlN, and TiN for extended tool life across a broad range of workpiece materials. The insert delivers a 0.189-inch cutting width and a maximum depth of cut of 0.15 inches, making it well-suited for controlled, repeatable grooving on production turning applications. The double-ended design maximizes usable cutting edges per insert.

This insert is part of the Notch-Grip series, which uses a clamp-style insert holding method for secure, repeatable indexing. It features a positive rake angle of 3 degrees and a lead angle of 3 degrees, reducing cutting forces and heat generation during operation. The corner radius is 0.023 inches. Rated for universal primary workpiece material compatibility, it covers ISO material groups H, K, M, P, and S, making it applicable to a wide range of metals including steel, stainless, cast iron, high-temp alloys, and non-ferrous materials in both light and medium-duty grooving scenarios.

Key Features

• 0.189-inch cutting width with a 0.15-inch maximum depth of cut
• Double-ended insert design provides two cutting edges per insert
• Positive rake geometry at 3 degrees reduces cutting forces and chip load
• Clamp-type insert holding method ensures rigid, repeatable seating in compatible toolholders
• Conforms to ISO 13399 standards for insert geometry and identification

Compatibility

Designed for use in Notch-Grip series clamping toolholders that accept ING-style inserts at insert seat size 3. Compatible with ISO material groups H, K, M, P, and S. MSC/Manufacturer reference number ING 3189R/L.

Installation Notes

This insert is installed and indexed by a machinist or CNC tooling technician using the appropriate Notch-Grip clamping toolholder. Power down and lock out the spindle before changing inserts. Use the correct clamp screw torque for the toolholder as specified by the toolholder manufacturer. Inspect the insert pocket and clamp for chips or debris before seating a new insert to ensure proper contact and prevent premature edge failure.
