Seco 00064433 Threading Insert 16 Tpi Un Carbide CP500

Product Description

The SECO 00064433 is a laydown threading insert designed for internal UN thread cutting at 16 threads per inch. Built from solid carbide with a CP500 grade designation and a PVD-applied TiAlN/TiN finish, this insert is engineered for consistent performance across a broad range of workpiece materials. It features a right-hand cutting orientation and a 60-degree included angle, matching the standard UN thread form. With a 3/8-inch inscribed circle and a thickness of 0.1366 inches, it seats reliably in compatible Snap-Tap toolholders. Machinists and CNC operators use this insert for precision internal threading on lathes and turning centers.

This insert is suited for internal threading operations on materials classified under universal workpiece categories, including ferrous, non-ferrous, and high-temperature alloy families indicated by material codes K, M, N, P, and S. It conforms to ISO standards and fits into the Snap-Tap series tooling system. Typical applications include threading bores on components in general machining, aerospace, and industrial fabrication environments where accurate UN thread profiles are required. The CP500 grade and TiAlN/TiN coating combination help maintain cutting-edge integrity across varying material hardnesses and cutting conditions.

Key Features

• Solid carbide construction with PVD-applied TiAlN/TiN finish for wear resistance
• CP500 manufacturer grade suited for universal workpiece materials
• 16 TPI internal UN thread profile with 60-degree included angle
• Right-hand cutting orientation for standard internal thread direction
• 3/8-inch inscribed circle for secure seating in Snap-Tap series holders
• ISO-standard geometry with 0.0050-inch corner radius for defined thread form

Compatibility

Designed for use in Snap-Tap series toolholders that accept the 16NR insert style with a 3/8-inch inscribed circle. Compatible with ISO-standard threading tooling systems accepting this insert geometry.

Installation Notes

This insert is installed by a machinist or CNC operator into a compatible Snap-Tap series threading toolholder. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket and clamping surfaces for chips or debris before installation to ensure proper seating and thread accuracy.
