Iscar 6403489 Grooving Insert XNUW14T303 IC08 Solid Carbide

Product Description

The ISCAR 6403489 is a solid carbide grooving insert in the V-Lock series, carrying the XNUW14T303 insert style designation and IC08 uncoated grade. Designed for parting and grooving operations on non-ferrous metals, this insert features a neutral hand orientation and a positive 7-degree rake angle that promotes clean chip formation and reduced cutting forces. With a cutting width of 0.5709 inches (14.50 mm) and an overall length of 0.5512 inches (14.00 mm), it is sized for precision groove profiles where dimensional accuracy is critical. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is intended for grooving and parting operations on non-ferrous workpiece materials, corresponding to ISO material group N. The IC08 uncoated solid carbide grade is well-suited for aluminum, copper, and other non-ferrous alloys where coating interaction with the workpiece material is a concern. The V-Lock series interface provides secure mechanical clamping in compatible ISCAR V-Lock toolholders, making it a common choice for lathe and turning center applications in production and job-shop environments.

Key Features

• Solid carbide IC08 uncoated grade optimized for non-ferrous metal machining
• Neutral hand orientation for flexible toolholder pairing
• Positive 7-degree rake angle for reduced cutting forces and clean chip evacuation
• 0.5709-inch cutting width for precise groove dimensioning
• V-Lock series interface for secure mechanical clamping in compatible holders
• Conforms to ISO 13399 tooling data standards for CAM and tooling management integration

Compatibility

Designed for use in compatible ISCAR V-Lock series grooving toolholders. Verify toolholder insert pocket specification accepts the XNUW 14T303 insert size before installation. This insert is rated for non-ferrous workpiece materials (ISO material group N) only.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Seat the insert firmly into the V-Lock pocket and confirm clamping screw torque per toolholder manufacturer guidelines before resuming cutting. Inspect the insert seat and clamping surfaces for chips or debris prior to each insert change to maintain accurate positioning.
