Seco 00068002 Threading Insert 6 Tpi Acme Solid Carbide

Product Description

The SECO 00068002 is a solid carbide laydown threading insert designed for external Acme thread cutting at 6 threads per inch (TPI). Carrying the CP500 manufacturer grade, this insert features a TiAlN/TiN PVD coating that extends tool life across a wide range of workpiece materials. The right-hand configuration and 29-degree included angle match standard Acme thread geometry. With an inscribed circle of 0.5000 inches (12.70 mm) and a thickness of 0.1854 inches (4.71 mm), the 00068002 fits 22ER-style insert pockets on compatible threading toolholders. It is part of the Snap Tap series and is installed by machinists and CNC operators performing precision threading operations.

This insert is suited for external Acme thread applications in both manual and CNC lathe environments. The universal primary workpiece material classification means it performs across cast iron, non-ferrous alloys, non-metals, steel, and heat-resistant superalloys, covering a broad range of production threading scenarios. ISO-standard geometry ensures consistent seating and thread form accuracy. The CP500 grade with PVD coating is a practical choice when threading materials that demand a balance of hardness and coating adhesion.

Key Features

• Solid carbide substrate with TiAlN/TiN PVD coating for extended cutting tool life
• 6 TPI Acme thread form with 29-degree included angle for accurate thread geometry
• Right-hand external threading configuration in 22ER insert style
• Inscribed circle of 0.5000 inches (12.70 mm) for standard 22ER pocket seating
• Universal workpiece material rating covering steel, cast iron, non-ferrous, and superalloy applications
• ISO-standard geometry for reliable, repeatable thread form accuracy

Compatibility

Designed as a replacement-style insert for 22ER-series threading toolholders accepting a 0.5000-inch inscribed circle and a 0.1854-inch insert thickness.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder pocket is clean and free of chips before seating the insert. Use the correct torque driver for the insert clamping screw to avoid cracking the carbide substrate. Confirm thread form and TPI requirements match the workpiece specification before beginning the threading pass.
