Vargus 52179 Threading Insert Solid Carbide Tialn 60 Degree

Product Description

The VARGUS 52179 is a solid carbide laydown threading insert designed for internal partial profile 60-degree thread cutting applications. Manufactured in the 3IRAG60 style and produced under the VTX grade, this insert features a TiAlN coating applied via PVD process, which provides strong oxidation resistance and extended tool life across a wide range of workpiece materials. The 52179 covers a thread pitch range of 48 to 8 TPI (0.50 to 3.00 mm) and carries a 3/8-inch inscribed circle with a corner radius of 0.0020 decimal inches. It is installed by machinists and tooling technicians on CNC lathes and turning centers performing internal threading operations.

This insert is suited for internal threading on a broad range of metallic workpiece materials, including ferrous, non-ferrous, stainless, heat-resistant alloys, and cast materials as indicated by primary workpiece material codes H, K, M, N, P, and S. The partial profile 60-degree thread form makes it applicable across standard 60-degree thread families without requiring a dedicated full-profile insert for each pitch. It is a right-hand insert and fits standard 3IR-style toolholders used in production and job-shop turning environments.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for extended wear resistance and thermal stability
• Partial profile 60-degree internal thread form covers 48 to 8 TPI (0.50 to 3.00 mm pitch) in a single insert
• 3IR insert style with 3/8-inch inscribed circle for compatibility with standard 3IR boring bar toolholders
• Right-hand cutting orientation for conventional internal threading setups
• Universal primary workpiece material rating across material codes H, K, M, N, P, and S
• Manufactured to ISO 9001:2008 quality standards

Compatibility

Designed for use in standard 3IR-style internal threading toolholders on CNC lathes and turning centers. Compatible with workpiece materials corresponding to ISO material codes H, K, M, N, P, and S as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before seating or replacing the insert in the toolholder. Ensure the insert pocket is clean and free of chips or debris before seating to prevent improper clamping and premature edge failure. Follow the toolholder manufacturer torque guidance for the clamping screw - do not overtighten.
