Vargus 50333 Laydown Threading Insert 2IR 14 Tpi Nptf

Product Description

The VARGUS 50333 is a solid carbide laydown threading insert designed for cutting right-hand internal NPTF threads at 14 threads per inch. Manufactured to the 2IR insert style with a 6.35 mm inscribed circle and a thickness of 3.17 mm, this insert delivers precise, repeatable thread forms on a wide range of workpiece materials. The PVD-applied TiN coating improves surface hardness and wear resistance, extending tool life in production environments. It is intended for use by machinists and toolroom professionals performing internal pipe thread operations on CNC lathes and manual threading equipment.

This insert is suited for internal NPTF pipe threading applications across general machining, fabrication, and maintenance operations. The universal material compatibility rating covers carbon steel, stainless steel, cast iron, aluminum, copper alloys, and high-temperature alloys, making it a practical choice for job shops and production floors handling mixed-material workloads. The single-tooth profile per side and 60-degree included angle conform to ANSI B1.20.3-1976 NPTF thread standards, ensuring proper taper and seal geometry on pipe fittings and hydraulic components.

Key Features

• Solid carbide construction for rigidity and thermal stability during high-speed threading
• PVD TiN coating applied for improved wear resistance and reduced built-up edge
• 14 TPI right-hand internal NPTF thread form, conforming to ANSI B1.20.3-1976
• 6.35 mm (1/4 inch) inscribed circle with 3.17 mm thickness fits standard 2IR toolholders
• Universal workpiece material compatibility including steel, stainless, cast iron, aluminum, copper alloys, and superalloys
• VKX manufacturer grade for consistent geometry and dimensional accuracy

Compatibility

Designed as an OEM-style replacement threading insert for standard 2IR-style laydown insert toolholders used in internal pipe threading operations.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the lathe or threading machine is fully powered down and locked out before seating or removing the insert. Use the correct torque driver and insert screw specified for the toolholder to avoid cracking the carbide. Verify toolholder alignment and insert seating before resuming cutting operations.
