Seco 00096260 Carbide Thread Mill Insert 8 Tpi Npt

Product Description

The SECO 00096260 is a carbide thread mill insert designed for external NPT thread milling operations at 8 threads per inch (TPI). Manufactured to insert style R396.19 with size code 4005 and grade F30M, this insert features a TiAlN/TiN finish applied via PVD coating process. The dual-layer coating improves wear resistance and heat dissipation during high-speed milling. This insert is intended for use by machinists and tooling specialists in CNC thread milling applications where accurate NPT external thread profiles are required.

This insert is suited for external NPT thread milling on a range of workpiece materials. The F30M grade and PVD-applied TiAlN/TiN coating make it compatible with cast iron, stainless steel, aluminum, non-ferrous metals, heat-resistant superalloys, and general steels, corresponding to material codes K, M, N, P, and S. It is a single-piece packaged item sold individually and is appropriate for production and job-shop environments where consistent thread form accuracy is critical.

Key Features

• Insert style R396.19 with size code 4005 for precise thread form geometry
• Carbide substrate with F30M grade for durability across multiple workpiece materials
• TiAlN/TiN dual-layer coating applied via PVD process for improved wear life
• External NPT thread profile at 8 TPI
• Non-conical insert geometry for standard thread milling toolholder compatibility
• Compatible with workpiece material codes K, M, N, P, and S

Compatibility

Designed for use with R396.19-series thread milling toolholders accepting size code 4005 inserts. Suitable for external NPT thread milling on cast iron (K), stainless steel (M), aluminum and non-ferrous (N), carbon and alloy steels (P), and heat-resistant superalloys (S).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable insert thread milling systems. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the correct torx or hex key as specified by the toolholder manufacturer when seating the insert to avoid insert breakage or improper seating. Follow the toolholder manufacturer's recommended cutting parameters for the F30M grade and the specific workpiece material being threaded.
