Iscar 6402647 Threading Insert IC528 Carbide Chamgroove

Product Description

The ISCAR 6402647 is a carbide threading insert designed for internal thread-cutting operations on CNC lathes and turning centers. Part of the ISCAR ChamGroove series, it features the GIQ insert style and carries a manufacturer grade of IC528 with a PVD coating process for extended tool life in demanding materials. The insert cuts a partial profile 60-degree thread form and is configured for right-hand operation. A 0.05 mm corner radius and MT chipbreaker geometry support chip control in tight-bore threading applications. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is suited for internal threading on a wide range of workpiece materials classified under material grades C3 and C7. The partial profile 60-degree thread standard covers common inch and metric thread families including 28 TPI and 0.90 mm pitch applications. The ChamGroove series is designed for groove-face threading and similar turning operations where insert geometry and coating performance directly affect thread quality and surface finish in production environments.

Key Features

• IC528 grade carbide with PVD coating for wear resistance in internal threading
• Partial profile 60-degree included angle covers both inch and metric thread families
• MT chipbreaker geometry for chip control in internal bore applications
• 0.05 mm corner radius for precise thread root form
• Right-hand cut orientation, insert size 11
• ISO 13399 compliant tooling data

Compatibility

Designed as an OEM-style replacement or production insert for ISCAR ChamGroove series internal threading toolholders accepting GIQ style inserts at insert size 11.

Installation Notes

Installation is performed by trained CNC machinists or tooling technicians. Before changing inserts, confirm the machine spindle is stopped and all axis motion is locked out per facility lockout/tagout procedures. Seat the insert fully and evenly in the pocket and use the manufacturer-recommended torque driver to secure the clamping screw — do not overtighten by hand. Verify thread pitch and hand orientation against the part drawing before beginning the threading cycle.
