The ISCAR 5902188 is a laydown-style threading insert engineered for external ISO thread cutting at a 1.50 mm pitch. Built from solid carbide and coated via PVD with a TiAlN finish under the IC908 grade designation, this insert delivers high wear resistance and thermal stability during turning operations. It carries a left-hand orientation and fits into compatible ISCARTHREAD toolholders. With a 3/8 inch (0.375 inch) inscribed circle and a thickness of 0.143 inches, this insert seats securely in the pocket and maintains consistent thread form across production runs. It is intended for use by CNC machinists and turning center operators working in metalworking environments.
This insert is suited for external ISO metric thread turning at 1.50 mm pitch on a wide range of workpiece materials. The IC908 grade with PVD TiAlN coating supports universal material application, including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and aluminum alloys, corresponding to ISO material codes P, M, K, N, S, and H. It is appropriate for both light production runs and higher-volume CNC threading operations where consistent thread geometry and insert life are priorities.
Designed for use with ISCARTHREAD series toolholders accepting 16EL-style laydown threading inserts with a 3/8 inch inscribed circle. Confirm holder pocket geometry and insert style code before installation.
Threading inserts should be installed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or changing inserts. Use the appropriate torx or insert clamping wrench specified by the toolholder manufacturer to achieve proper clamp force without over-torquing the insert screw. Verify insert orientation and hand designation against the toolholder before initiating any threading cycle.
