Seco 00096249 Carbide Thread Mill Insert 12 Tpi Un F30M

Product Description

The SECO 00096249 is a carbide thread mill insert designed for internal UN thread milling applications. Manufactured in grade F30M and coated with a TiAlN/TiN finish, this insert delivers wear resistance and thermal stability during threading operations. With a thread pitch of 12 TPI (threads per inch) and insert style designation 396.19 with size code 4003, it is sized for consistent, repeatable thread profiles. The conical geometry is not applicable to this design. Machinists and tooling professionals install this insert as a replacement component in compatible thread mill bodies.

This insert is suited for internal thread milling on a range of workpiece materials including cast iron, stainless steel, non-ferrous alloys, steel, and superalloys, corresponding to material codes K, M, N, P, and S. It is used in CNC machining centers performing UN-standard internal threading where a replaceable insert platform is preferred over solid thread mills. Typical applications include production environments requiring frequent insert changes without retooling the entire cutter body.

Key Features

• Carbide substrate with TiAlN/TiN coating for extended tool life in demanding materials
• 12 TPI UN internal thread form for standard unified thread applications
• Insert style 396.19, size code 4003 for precise fitment in compatible holders
• F30M manufacturer grade balances hardness and toughness across multiple workpiece material groups
• Non-conical geometry provides straightforward indexing and seating in the cutter body
• Compatible workpiece material codes: K, M, N, P, S

Compatibility

Designed as a replacement insert for thread mill cutter bodies accepting insert style 396.19, size code 4003. Specific cutter body compatibility should be verified against SECO tooling documentation for the 396.19 insert platform.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Use the correct torx or hex key as specified by the cutter body manufacturer to seat the insert securely without over-torquing the clamping screw. Verify insert seating and thread engagement before resuming cutting operations.
