Vargus 52497 Threading Insert 14 Tpi 3/8 in Internal Un

Product Description

The VARGUS 52497 is a solid carbide laydown threading insert designed for internal UN thread cutting on CNC lathes and threading machines. Carrying the VKX manufacturer grade and a TiN (titanium nitride) coating, this insert delivers consistent thread form and extended tool life on a wide range of workpiece materials. It is configured as a right-hand insert with a 3IR insert style and a 3/8-inch inscribed circle, cutting at 14 threads per inch. The TiN finish reduces friction and resists built-up edge, making it a dependable choice for production threading operations where dimensional accuracy and repeatability are required.

This insert is suited for internal UN thread applications in job shop and production turning environments. It is typically used by machinists and CNC operators threading bores on ferrous and non-ferrous workpieces to Unified National thread standards. The 14 TPI specification makes it well matched to fastener-grade bore threading in mid-range pitch applications. Insert style 3IR seats in standard laydown toolholders designed for that geometry, allowing quick indexing without disturbing the toolholder setup.

Key Features

• Solid carbide substrate provides rigidity and wear resistance for precise thread profiles
• TiN coating reduces cutting friction and extends edge life in threading operations
• Right-hand internal configuration for UN standard bore threading
• 14 TPI cutting geometry for consistent Unified National thread form
• 3/8-inch inscribed circle, insert style 3IR for laydown toolholder compatibility
• VKX grade designation ensures manufacturer-specified geometry and tolerances

Compatibility

Designed as an OEM-style replacement threading insert for laydown toolholders accepting 3IR insert geometry in internal UN threading applications.

Installation Notes

Indexable threading inserts should be installed by qualified machinists or CNC operators following the toolholder manufacturer torque and seating procedures. Power down and lock out the spindle before indexing or replacing inserts. Inspect the toolholder pocket and clamping screw for wear or damage before seating a new insert. Do not run the insert beyond its effective cutting edge to avoid thread form degradation.
