Seco 00072792 Laydown Threading Insert 5 Tpi Acme

Product Description

The SECO 00072792 is a solid carbide laydown threading insert designed for cutting internal Acme threads at 5 threads per inch. Manufactured to an included angle of 29 degrees and ground to a 1/2 inch inscribed circle with a thickness of 0.1854 inches, this insert is built for consistent thread form accuracy on a right-hand cutting path. The CP500 grade substrate uses a micrograin carbide matrix with a PVD-applied TiAlN/TiN coating, which extends edge life across a broad range of workpiece materials. It belongs to the Snap Tap series and conforms to ISO standards for threading insert geometry.

This insert is suited for internal Acme thread applications in CNC lathes and turning centers where precision thread form and repeatable insert positioning are required. The right-hand configuration and laydown style make it a practical choice for threading operations on threaded rod, leadscrew bores, and similar components across general machining, production, and repair environments. Its universal material grade compatibility makes it appropriate for a wide variety of ferrous and non-ferrous workpieces including cast iron, aluminum, steel, stainless, and heat-resistant alloys.

Key Features

• Solid carbide construction with micrograin substrate for edge stability under threading loads
• PVD TiAlN/TiN coating applied for extended tool life and reduced built-up edge
• 29-degree included angle conforms to standard Acme thread form geometry
• Right-hand internal thread cutting orientation in laydown insert style
• ISO-standard geometry for compatibility with appropriate Snap Tap toolholders
• Universal workpiece material grade covers steel, stainless, cast iron, aluminum, and superalloys

Compatibility

Designed for use in SECO Snap Tap series toolholders accepting 22NR-style laydown threading inserts for internal Acme thread applications.

Installation Notes

Threading inserts should be installed by a qualified machinist using the appropriate torque wrench and insert screw specified by the toolholder manufacturer. Always confirm the spindle is fully stopped and the machine is in a safe state before changing inserts. Inspect the insert seat and clamping mechanism for debris or wear before seating a new insert. Do not exceed the recommended depth of cut or feed rate parameters established for the toolholder and workpiece material combination.
