Iscar 5902285 Laydown Threading Insert 12 Tpi Acme

Product Description

The ISCAR 5902285 is a solid carbide laydown threading insert designed for cutting external Acme threads on a lathe or threading machine. It carries the IC908 manufacturer grade with a PVD-applied TiAlN coating, which improves wear resistance and tool life across a wide range of workpiece materials. The insert follows the 16ER style designation, features a 3/8 inch (0.375 inch decimal) inscribed circle, and a thickness of 0.143 inches. It is engineered to produce right-hand Acme thread forms at 12 threads per inch. Licensed machinists, toolroom technicians, and CNC lathe operators are the primary users of this insert.

This insert is suited for external Acme thread cutting in general machining environments, including job shops, maintenance and repair operations, and production facilities. The IC908 grade with TiAlN coating supports universal workpiece material compatibility, covering steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials as indicated by the H, K, M, N, P, and S material codes. It is a practical choice wherever Acme-profile lead screws, power screws, or linear motion components require threading.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or changing inserts. Use the correct torque driver or clamping screw as specified by the toolholder manufacturer — do not overtighten the clamping screw. Verify thread pitch and insert orientation against the job drawing before cutting.
