Seco 00096243 Carbide Thread Mill Insert 16 Tpi Un

Product Description

The SECO 00096243 is a carbide thread mill insert engineered for internal UN thread milling applications at 16 threads per inch (TPI). Manufactured in the F30M grade carbide with a TiAlN/TiN finish, this insert is built for consistent performance across a range of workpiece materials including aluminum, stainless steel, non-ferrous metals, and steel. The 396.19 insert style paired with the 4003 size code positions this insert as a precise, application-specific cutting tool for thread milling operations on CNC machining centers. Machinists and tool room technicians working with UN-standard internal threading applications will find this insert well-suited to production and prototype environments.

This insert is intended for internal thread milling of UN-profile threads at 16 TPI. It is suited for use in metalworking applications involving workpiece material groups K, M, N, P, and S — covering cast iron, stainless steel, non-ferrous materials, steel, and heat-resistant superalloys. Typical installation scenarios include CNC thread milling on lathes and machining centers where a dedicated insert-style thread mill is preferred over a solid carbide tool. The non-conical geometry keeps the insert profile consistent for straight-wall thread forms.

Key Features

• Carbide substrate with TiAlN/TiN coating for wear resistance and extended tool life
• F30M manufacturer grade designed for broad material compatibility
• 16 TPI internal UN thread profile — non-conical geometry
• Compatible with workpiece material groups K, M, N, P, and S
• Insert style 396.19, size code 4003 for precise holder matchup
• Package quantity of 1 insert per pack; minimum order quantity of 2

Compatibility

Designed for use with SECO 396.19 series thread mill insert holders accepting the 4003 size code. Verify holder compatibility against the specific toolholder documentation before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable insert thread milling tooling. Ensure the machine spindle is fully stopped and locked out before changing or seating the insert. Use the correct insert clamping torque as specified in the toolholder manufacturer documentation — do not over-torque the clamping screw. Confirm the insert is fully seated and secure before resuming cutting operations.
