Seco 00049782 Laydown Threading Insert 16ER11BSPT CP500

Product Description

The SECO 00049782 is a laydown threading insert designed for external BSPT thread cutting on CNC lathes and turning centers. Manufactured from solid carbide in the CP500 grade with a micrograin substrate, it carries a PVD-applied TiAlN/TiN coating for heat resistance and extended edge life. The insert is sized at a 3/8-inch (0.3750-inch) inscribed circle with a thickness of 0.1366 inches and cuts at 11 threads per inch with a 55-degree included angle. Right-hand orientation is standard. This insert is part of the Snap Tap series and is intended for use by machinists and tool-and-die professionals working to ISO threading standards.

This insert is suited for external BSPT (British Standard Pipe Taper) threading operations in production and job-shop environments. The universal primary workpiece material classification makes it compatible with a broad range of materials, including cast iron, steel, stainless, non-ferrous metals, and high-temp alloys (material codes K, M, N, P, S). It is typically applied in threading operations for pipe fittings, hydraulic components, and pneumatic fittings where BSPT form accuracy is required. Minimum order quantity is 2 inserts; each package contains 1 insert.

Installation Notes

Installation is performed by machinists on CNC or manual turning equipment. Power down and lock out the machine spindle before seating or changing inserts. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the insert without over-torquing the clamping screw. Verify insert seating and thread form with a certified thread gauge before running production parts.
