Iscar 2411892 FLT3R IC908 Threading Insert 6-20 Tpi

Product Description

The ISCAR 2411892 is a carbide threading insert in the FLT3R IC908 configuration, designed for precision thread-cutting on CNC lathes and turning centers. Manufactured from fine grain carbide with an IC908 grade coating applied via PVD process, this insert handles both internal and external threading operations. It covers an internal pitch range of 5-12 TPI and an external pitch range of 6-20 TPI, conforming to ISO and UN thread standards. The 60-degree included angle suits the most common unified and metric thread profiles. Machinists and CNC operators in production and job-shop environments install this insert for consistent thread form and tool life on ferrous and non-ferrous workpieces.

This insert is suited for internal and external threading applications in both production turning and job-shop settings. The Notch-Grip series design provides secure clamping in compatible toolholders, reducing insert shift during interrupted cuts or heavy threading passes. The right-hand cutting orientation is standard for conventional thread-turning setups. It fits applications where ISO 13399 tooling data compliance is required for digital tool management systems.

Key Features

• IC908 grade PVD-coated fine grain carbide for extended wear resistance in threading operations
• Covers external pitch 6-20 TPI and internal pitch 5-12 TPI in a single insert
• 60-degree included angle compatible with ISO and UN thread standards
• Right-hand cutting orientation for standard thread-turning setups
• Notch-Grip series seat design for positive, repeatable insert location in the toolholder
• Compliant with ISO 13399 for integration with digital tool management platforms

Compatibility

Designed for use in Notch-Grip series threading toolholders compatible with size 3R inserts. Consult the ISCAR toolholder selection guide to confirm seat geometry and clamping compatibility before installation.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer - do not over-torque the clamping screw, as this can crack the carbide insert. Verify insert seating and thread form with a first-article check before running production.
