Iscar 6404242 Grooving Insert GIF400E040F IC808 Carbide

Product Description

The ISCAR 6404242 is a solid carbide grooving insert in the Cut-Grip series, designed for external and internal grooving, parting, and turning operations on CNC lathes and turning centers. The insert carries the GIF400E040F geometry with ISCAR grade IC808, a submicron carbide substrate with a PVD-applied multilayer coating of AlTiN, TiAlN, and TiN. Cutting width is 3.99 mm (0.157 inches), with a maximum depth of cut of 13 mm (0.512 inches). The double-ended design extends tool life by providing two usable cutting edges per insert. This insert is installed by machinists and tool-room technicians running production or maintenance turning operations.

The GIF400E040F is suited for universal material applications, including steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, as indicated by the primary workpiece material codes H, K, M, P, and S. The Cut-Grip series uses a self-grip clamping method, meaning the insert seats and locks directly in a matching Cut-Grip toolholder without a separate clamp screw. This makes it appropriate for moderate to high cutting speeds where quick insert indexing is a priority. Typical use is on production lathes in job shops, aerospace, and general machining environments.

Key Features

• IC808 submicron carbide grade with PVD multilayer AlTiN, TiAlN, and TiN coating for wear resistance across universal workpiece materials
• 3.99 mm (0.157 inches) cutting width with a 0.41 mm (0.016 inches) corner radius for controlled groove geometry
• Maximum depth of cut 13 mm (0.512 inches), with an applicable range of 10 mm to 20 mm
• Double-ended insert — two usable cutting edges per insert reduces per-edge tooling cost
• Self-grip clamping method seats securely in matching Cut-Grip toolholders without an additional clamping screw
• Positive rake angle of 7 degrees with F chip breaker geometry for controlled chip evacuation

Compatibility

Designed for use in ISCAR Cut-Grip series toolholders that accept the GIF insert style and 400E040 insert size. Compatible workpiece material codes are H, K, M, P, and S, covering steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys. Conforms to ISO 13399 standards with Iso Code GIF 4.00E-0.40.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before indexing or replacing the insert. The self-grip design requires a matching Cut-Grip toolholder pocket — do not force the insert into a non-compatible holder seat. Inspect the insert pocket for chips or debris before seating to ensure proper contact and grip.
