Seco 00072805 Threading Insert 6 Tpi Internal Acme

Product Description

The SECO 00072805 is a solid carbide laydown threading insert designed for cutting internal Acme threads. It carries a 29-degree included angle and is engineered for right-hand thread applications at 6 threads per inch (TPI). The insert features a TiAlN/TiN coating applied via PVD process, which improves wear resistance and extends tool life across a broad range of workpiece materials. With an inscribed circle of 0.5 inches and a thickness of 0.1854 inches, this insert is part of the Snap Tap series and conforms to ISO standards. Installation and use require standard CNC lathe or threading tool holders compatible with the 22NR insert style.

This insert is suited for threading operations on a wide range of materials, including ferrous metals, non-ferrous alloys, and heat-resistant alloys, as indicated by its universal primary workpiece material classification covering K, M, N, P, and S material grade codes. It is appropriate for internal Acme thread forms found in lead screws, power transmission components, and hydraulic cylinder rods. Machinists and CNC operators working in manufacturing, repair, or production environments will find this insert applicable to both light and medium threading passes. The Micrograin carbide substrate supports consistent edge integrity across production runs.

Installation Notes

This insert is installed and serviced by qualified machinists or CNC tooling technicians. Power down and lock out the machine fully before changing inserts. Use the appropriate torque wrench and insert screw specified for the 22NR tool holder to avoid seat damage. Verify thread form, TPI, and hand orientation against job requirements before beginning a cut.
