Seco 00073085 Threading Insert 7 Tpi Un Solid Carbide

Product Description

The SECO 00073085 is a laydown threading insert designed for cutting internal UN threads at 7 threads per inch. Built from solid carbide and finished with a PVD-applied TiAlN/TiN coating, this insert delivers wear resistance across a wide range of workpiece materials. It carries the CP500 manufacturer grade and fits the 22NR insert style. With a 0.5000-inch inscribed circle and a thickness of 0.1854 inches, it seats precisely in compatible Snap Tap toolholders. The 60-degree included angle is standard for UN thread forms, and the right-hand orientation suits the majority of internal threading applications on CNC lathes and turning centers.

This insert is intended for internal threading operations producing Unified National (UN) thread forms. It is classified for use across universal workpiece material categories, including ISO material groups K, M, N, P, and S, making it applicable to cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. Machinists and CNC operators in job shops, production facilities, and maintenance environments use this insert when threading bores, nuts, and through-holes to UN standards. It is sold individually per package with a minimum order quantity of 2 pieces.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Before indexing or replacing an insert, power down the spindle and confirm the turret is fully stopped and locked. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified seating procedure without over-torquing the clamping screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and accurate thread geometry.
