Seco 00049826 Threading Insert 14 Tpi Npt Solid Carbide

Product Description

The SECO 00049826 is a laydown threading insert designed for cutting external NPT threads on a wide range of workpiece materials. Built from micrograin solid carbide with a PVD-applied TiAlN/TiN coating in the CP500 grade, this insert delivers consistent thread geometry and extended edge life in production threading operations. It carries a 16ER insert style designation and is configured for right-hand cutting with a 60-degree included angle standard to NPT profiles. At 14 threads per inch (TPI), it produces the tapered pipe thread form required for pressure-tight pipe and fitting connections. Machinists and toolroom operators working on CNC lathes or threading machines are the primary users of this insert.

This insert is suited for external NPT threading applications across universal workpiece material categories, including cast iron, non-ferrous, non-metallic, steel, and high-temperature alloys as indicated by material codes K, M, N, P, and S. It fits into the Snap Tap series toolholding system and is appropriate for job shops and production environments where repeatable pipe thread profiles are required on parts such as fittings, nipples, and manifold bodies. The ISO-standard geometry ensures dimensional consistency across qualified toolholder setups.

Key Features

• Micrograin solid carbide substrate with PVD TiAlN/TiN coating in CP500 grade for wear resistance across universal material groups
• 16ER insert style for right-hand external NPT thread cutting at 14 TPI
• 60-degree included angle matches standard NPT thread form for pressure-rated pipe connections
• 3/8 inch inscribed circle (0.3750 inches) for compatibility with Snap Tap series toolholders
• ISO-standard geometry ensures consistent thread profile and interchangeability in qualified setups
• Corner radius of 0.0030 inches supports accurate thread root form on tapered pipe profiles

Compatibility

Designed for use in Snap Tap series toolholders accepting the 16ER insert style with a 3/8 inch inscribed circle. Suitable for universal workpiece material grades including material codes K, M, N, P, and S.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's seating and clamping specifications. Power down and lock out the machine before indexing or replacing inserts. Verify insert seating and toolholder cleanliness before engaging a cut to prevent thread-form deviation. Follow the toolholder manufacturer's recommended clamping torque procedure for 16ER-style laydown inserts.
