Vargus 52176 Threading Insert Solid Carbide Tin 3/8 in Ic

Product Description

The VARGUS 52176 is a solid carbide laydown threading insert designed for right-hand internal thread cutting. It carries a TiN coating applied via PVD process and conforms to a 60-degree partial profile thread standard. The insert features a 3/8 inch inscribed circle, a corner radius of 0.0020 inches, and covers a thread pitch range of 48 to 8 TPI (0.50 to 3.00 mm pitch). Manufactured to ISO 9001:2008 standards, the VKX grade targets a wide range of workpiece materials. Machinists and toolroom technicians use this insert on CNC lathes and threading machines requiring precision internal thread forms.

This insert suits internal threading operations across a broad spectrum of materials, classified under universal primary workpiece material codes H, K, M, N, P, and S. That range covers hardened steels, cast iron, stainless and heat-resistant alloys, non-ferrous metals, carbon and alloy steels, and superalloys. Typical applications include threading bores, tapped features, and internal thread profiles in production and job-shop environments. The partial profile 60-degree geometry makes it adaptable across multiple thread standards without requiring a dedicated insert per pitch.

Key Features

• Solid carbide VKX grade construction for wear resistance across universal workpiece materials
• TiN coating via PVD process for improved surface hardness and tool life
• Right-hand internal partial profile 60-degree thread form covering 48 to 8 TPI
• 3/8 inch inscribed circle with 0.0020 inch corner radius for consistent thread geometry
• Compatible pitch range of 0.50 to 3.00 mm supports a wide variety of thread standards
• Manufactured under ISO 9001:2008 quality system

Compatibility

Designed as a replacement-style laydown threading insert for CNC lathes and threading setups requiring a 3IR insert style with a 3/8 inch inscribed circle and 60-degree internal partial profile geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torx or clamping screw specified by the toolholder manufacturer to secure the insert - do not overtighten by feel alone. Verify insert seating and confirm thread pitch selection against the job drawing before resuming cutting operations.
