Seco 00096261 Carbide Thread Mill Insert Nptf 11.5 Tpi

Product Description

The SECO 00096261 is a solid carbide thread mill insert designed for cutting NPTF tapered pipe threads at 11.5 teeth per inch (TPI). Built to insert style R396.19 with a size code of 4003, this insert handles both internal and external thread milling operations in a single tool. Manufactured to grade F30M carbide, it is suited for demanding thread milling applications where dimensional accuracy and tool life are critical. Licensed machinists and CNC operators install this insert in compatible thread mill bodies for production and maintenance threading on pipe fittings, manifolds, and fluid system components.

This insert is used in CNC machining centers performing NPTF thread milling on a wide range of workpiece materials. The universal primary workpiece material rating covers cast irons, steels, stainless steels, non-ferrous metals, and superalloys, corresponding to ISO material groups K, M, N, P, and S. It is appropriate for both job shop and production environments where NPTF pipe thread forms are required in internal bores and on external cylindrical features. The non-conical geometry keeps the insert profile straightforward for standard NPTF thread forms without taper correction offsets.

Key Features

• Handles both internal and external NPTF thread milling in one insert
• 11.5 TPI matches the NPTF standard for tapered pipe threads
• F30M carbide grade provides a balance of hardness and toughness for universal material groups
• Non-conical insert geometry simplifies programming and setup
• Compatible with ISO workpiece material groups K, M, N, P, and S
• Insert style R396.19 with size code 4003 for repeatable, indexed replacement

Compatibility

Designed for use in SECO R396.19 series thread mill bodies that accept the 4003 insert size. Confirm holder compatibility by matching insert style and size code before ordering. No additional compatible model numbers were specified in the product data.

Installation Notes

Installation and replacement should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the spindle before seating or removing the insert. Use the correct insert screw torque driver specified by the tool body manufacturer to avoid damaging the seating pocket. Verify NPTF thread form and pitch accuracy with a calibrated thread gauge after the first part cycle.
