Seco 00096256 Carbide Thread Mill Insert 6 Tpi Internal Un

Product Description

The SECO 00096256 is a carbide thread mill insert designed for internal threading operations on CNC milling machines. Manufactured to insert style 396.19 with size code 4005, this insert carries a TiAlN/TiN finish that improves wear resistance and extends tool life in demanding cutting environments. The F30M manufacturer grade identifies it as a multi-layer coated carbide suitable for a range of workpiece materials. At 6 teeth per inch (TPI), it is configured for UN thread standards, making it a direct fit for common unified national thread profiles. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is suited for internal thread milling in materials classified under workpiece codes K, M, N, P, and S, covering cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. It is a non-conical insert, appropriate for standard thread mill bodies that accept the 396.19 insert style. Typical applications include production machining in job shops, aerospace component manufacturing, and general industrial CNC operations where consistent thread geometry and finish quality are required.

Key Features

• F30M grade carbide optimized for multi-material cutting applications
• 6 TPI configuration for UN internal thread profiles
• Insert style 396.19, size code 4005, for compatibility with matching thread mill bodies
• Non-conical geometry for standard thread milling operations
• Compatible with workpiece materials including steel, stainless, cast iron, non-ferrous, and superalloys

Compatibility

Designed for use with thread mill tool bodies that accept the 396.19 insert style in size code 4005. Suitable for internal UN thread milling across workpiece material groups K, M, N, P, and S.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Ensure the machine spindle is fully stopped and the tool body is secured before seating or removing the insert. Follow the tool body manufacturer's torque specifications for the clamping screw, and inspect the insert seating pocket for chips or debris before mounting. Verify thread specification and insert orientation match the programmed toolpath before running the first part.
