Seco 00049966 Threading Insert 8 Tpi Solid Carbide CP500

Product Description

The SECO 00049966 is a laydown threading insert designed for external round thread cutting operations. Built from solid carbide with a TiAlN/TiN PVD coating applied under the CP500 grade designation, this insert delivers wear resistance across a broad range of workpiece materials. It follows the 16ER insert style with an 8 threads per inch (TPI) pitch, a 9.53 mm inscribed circle, and a thickness of 3.47 mm (0.1366 inches). The 30-degree included angle and 0.730-inch corner radius are sized for right-hand external round thread profiles to ISO standards. Machinists and CNC tool setters install this insert in compatible Snap-Tap toolholders on turning centers and lathes.

This insert is suited for threading operations on a universal range of workpiece materials, covering ISO material codes K, M, N, P, and S. That broad compatibility makes it a practical choice for job shops and production environments cutting threads in cast iron, non-ferrous alloys, steel, stainless, and superalloys. The right-hand orientation is standard for conventional external threading passes. It is sold individually with a minimum order quantity of 2 pieces.

Installation Notes

This insert is installed and replaced by machinists or CNC tooling technicians on turning equipment. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert seat and clamping screw for debris or wear before seating a new insert.
