Iscar 5902822 Threading Insert 18 Tpi Npt Solid Carbide

Product Description

The ISCAR 5902822 is a laydown-style threading insert designed for cutting external NPT threads at 18 threads per inch (TPI). Built from solid carbide with a TiAlN coating applied via PVD process, this insert carries the IC908 manufacturer grade and is suited for demanding threading operations across a broad range of workpiece materials. The right-hand orientation and B chipbreaker geometry are integrated into the 16ERB insert style. The insert measures 0.375 inches inscribed circle diameter and 0.143 inches thick, fitting standard laydown threading toolholders used in production and maintenance threading applications.

This insert is intended for external NPT thread profiles on metal workpieces, covering a universal material range including ferrous, non-ferrous, stainless, heat-resistant alloys, and cast materials as indicated by the H, K, M, N, P, and S workpiece material codes. It is commonly used by machinists and tool-and-die professionals on CNC lathes and manual turning centers where pipe thread connections must meet NPT specifications. The IC908 grade with PVD TiAlN coating provides wear resistance suitable for both interrupted and continuous threading cuts.

Compatibility

Designed as a replacement-style laydown threading insert for toolholders accepting the 16ERB insert style. Consult your toolholder documentation to confirm insert pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and locked out before seating or changing the insert. Use the correct torx or hex key for the clamping screw and avoid overtightening, which can fracture carbide. Confirm thread form and pitch with a calibrated NPT thread gauge after the first pass.
