Seco 00046164 Threading Insert 48-16 Tpi 1/4 in Ic

Product Description

The SECO 00046164 is a solid carbide laydown threading insert designed for right-hand internal threading operations. It carries a CP500 manufacturer grade with a TiAlN/TiN PVD coating applied for wear resistance and extended tool life. This insert covers a partial profile 60-degree thread form across a 48-16 TPI range, equivalent to a 0.50-1.50 mm pitch. The 1/4 inch inscribed circle and 0.1181 inch thickness conform to standard laydown insert geometry. It is intended for use by machinists and CNC lathe operators performing internal threading passes on a variety of workpiece materials.

This insert fits into the Snap-Tap series tooling system and is rated for universal primary workpiece material compatibility, including material codes K, M, P, and S, covering cast iron, stainless steel, steel, and heat-resistant superalloys. Typical applications include production threading of internal bores on machined components in general manufacturing, aerospace, and industrial fabrication environments. The partial profile 60-degree thread form makes it suitable for cutting unified and metric 60-degree thread forms within its stated TPI and pitch range without a full-form edge grind.

Key Features

• Solid carbide substrate with CP500 grade designation for toughness and wear resistance
• TiAlN/TiN PVD coating for elevated heat resistance and reduced built-up edge
• Partial profile 60-degree thread form covers 48-16 TPI (0.50-1.50 mm pitch) in a single insert
• Right-hand cut geometry for standard internal threading operations
• 1/4 inch inscribed circle with 0.0030 inch corner radius for precise thread root engagement
• ISO-standard geometry compatible with Snap-Tap series insert holders

Compatibility

Designed for use in Snap-Tap series threading toolholders accepting 11NR-style laydown inserts with a 1/4 inch inscribed circle. Compatible with workpiece material codes K, M, P, and S as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool turret is de-energized before inserting or changing inserts. Seat the insert fully into the pocket and verify clamp engagement before resuming cutting operations. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid insert cracking or poor seating.
