Vargus 028-00335 Laydown Threading Insert 18 Tpi Npt

Product Description

The VARGUS 028-00335 is a solid carbide laydown threading insert designed for cutting right-hand internal NPT threads at 18 threads per inch. Part of the VARGUS Mini 3 series, it features a TiN coating applied via PVD process and a 60-degree included angle suited to NPT thread form. The insert has a 6.00 mm inscribed circle and a thickness of 2.60 mm. It is intended for use by machinists and toolroom technicians working with CNC or manual lathes requiring precise internal thread profiles in pipe-fitting and fluid-system components.

This insert is rated for universal workpiece material compatibility and carries material codes H, K, M, N, P, and S, covering a broad range of ferrous, non-ferrous, and heat-resistant alloys. Typical applications include threading of pipe couplings, fittings, and valve bodies requiring NPT-standard internal threads. The Mini 3 series format makes it well suited for small-bore internal threading operations where compact toolholder clearance is a priority.

Key Features

• Right-hand internal NPT thread form at 18 TPI with a 60-degree included angle
• Solid carbide substrate with TiN coating via PVD process for wear resistance
• 6.00 mm inscribed circle in a laydown insert geometry for secure seating
• 2.60 mm insert thickness for rigidity in small-bore internal threading
• Universal workpiece material compatibility across material codes H, K, M, N, P, and S
• Conforms to ISO 9001:2008 and USAS B2.1:1968 standards

Compatibility

Designed for use with VARGUS Mini 3 series threading toolholders that accept the 6.0KIR insert style. Confirmed thread standard compatibility is NPT internal per USAS B2.1:1968.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or changing inserts. Verify correct insert orientation for right-hand internal threading before engaging the workpiece. Follow all applicable shop safety procedures when handling carbide cutting tools.
