Seco 00050449 Threading Insert 10 Tpi Un Solid Carbide CP500

Product Description

The SECO 00050449 is a laydown-style threading insert engineered for internal UN thread cutting at 10 threads per inch. Built from micrograin solid carbide in the CP500 grade, this insert carries a PVD-applied TiAlN/TiN coating that extends cutting edge life across a wide range of workpiece materials. The 60-degree included angle and right-hand orientation make it a direct fit for standard UN internal threading operations. With a 3/8 inch inscribed circle and a thickness of 0.1366 inches, the insert seats consistently in compatible laydown toolholders. Licensed machinists and CNC lathe operators working on precision threading applications are the primary users of this insert.

This insert is suited for internal threading on universal workpiece materials, including cast iron, steel, non-ferrous metals, and heat-resistant alloys as indicated by material codes K, M, N, P, and S. It belongs to the Snap Tap series and is used in production and job-shop environments where repeatable thread form and dimensional accuracy are required on UN-specification internal threads. The ISO-standard geometry ensures compatibility with metric toolholder systems designed to accept 16NR-style laydown inserts.

Key Features

• Micrograin solid carbide substrate in CP500 grade for edge stability and wear resistance
• PVD-applied TiAlN/TiN coating extends tool life across universal workpiece materials
• 10 TPI internal UN thread profile with a 60-degree included angle for standard UN forms
• Right-hand cutting orientation for conventional internal threading passes
• 3/8 inch inscribed circle seats reliably in 16NR-compatible laydown toolholders
• ISO-standard geometry for consistent seating and repeatable thread accuracy

Compatibility

Designed for use in 16NR-style laydown threading toolholders that accept a 3/8 inch inscribed circle insert. Intended for internal UN threading applications where a 10 TPI, right-hand insert with ISO-standard 16NR geometry is specified.

Installation Notes

Insert replacement should be performed with the machine spindle fully stopped and the toolholder removed or secured per shop lockout/tagout procedures. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to seat the insert without over-torquing the clamp. Verify insert orientation and seating before resuming cutting operations. Minimum order quantity for this insert is 2 pieces; each package contains 1 insert.
