Iscar 6403292 Threading Insert 1.00mm Iso IC908 Carbide

Product Description

The ISCAR 6403292 is a TIP-style carbide threading insert designed for external ISO thread cutting on CNC lathes and turning centers. Running in the IC908 grade with a PVD coating, this insert handles a 1.00 mm pitch at a 60-degree included angle, making it a standard choice for metric ISO thread profiles. The Cut Grip series designation indicates compatibility with ISCAR Cut Grip toolholders that use the TIP insert geometry. With a cutting tip width of 2.39 mm and a corner radius of 0.15 mm, it delivers consistent thread form on steel, stainless, and similar workpiece materials. Carbide machinists and CNC operators install this insert as a direct indexed replacement during production runs.

This insert is suited for external threading operations in precision machining environments, including job shops, production facilities, and maintenance machining. It targets ISO metric thread standards and is applied on lathes equipped with Cut Grip-compatible toolholders. The IC908 grade is designed for a range of steel and alloy materials, and the PVD coating process helps maintain edge integrity at typical threading feeds and speeds. The TIP insert style with size designation 2 fits the corresponding pocket geometry in the toolholder system.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket is clean and free of chips before clamping to maintain proper seating and thread form accuracy. Follow the toolholder manufacturer torque guidelines for the clamping screw and verify thread profile with the first part before committing to a production run.
