Iscar 5902352 Threading Insert 16 Tpi Left Hand Un

Product Description

The ISCAR 5902352 is a solid carbide laydown threading insert designed for left-hand external UN thread cutting at 16 threads per inch. Built to the IC908 grade with a PVD-applied TiAlN coating, this insert delivers consistent thread form on a broad range of workpiece materials. The 3/8 inch (0.375 inches) inscribed circle and 0.143 inch thickness conform to standard laydown seating geometry, allowing drop-in use in compatible toolholders. Licensed machinists and CNC lathe operators in production and job-shop environments rely on IC908-grade inserts for their toughness and wear resistance across interrupted and continuous threading cuts.

This insert is suited for external UN threading operations on lathes and turning centers where left-hand thread forms are required. The universal primary workpiece material rating covers a wide cross-section of metals, including steel, stainless steel, cast iron, aluminum, and superalloys, as indicated by material codes H, K, M, N, P, and S. It fits within the ISCARTHREAD series toolholder system and is intended for applications demanding precise 16 TPI UN thread profiles on left-hand threaded components.

Key Features

• IC908 solid carbide grade with PVD TiAlN coating for extended tool life
• 16 TPI left-hand external UN thread form in laydown insert style
• 3/8 inch inscribed circle for standard laydown toolholder compatibility
• Universal material compatibility covering steel, stainless, cast iron, aluminum, and superalloys
• Corner radius of 0.007 inches (0.18 mm) for accurate thread root form
• Compliant with ISO 13399 cutting tool data representation standard

Compatibility

Designed for use with ISCARTHREAD series toolholders that accept 16EL style laydown threading inserts with a 3/8 inch inscribed circle seating geometry.

Installation Notes

Threading inserts must be seated fully and clamped securely in the toolholder before initiating any cut. Power down and lock out the machine spindle before changing inserts. Verify that the toolholder and insert style codes match before installation, as mixing incompatible geometries can result in insert failure or thread-form error. This insert is a precision cutting tool; handle the cutting edges with care to avoid chipping prior to use.
