Iscar 5992247 Laydown Threading Insert 1.50mm Iso IC908

Product Description

The ISCAR 5992247 is a solid carbide laydown threading insert engineered for internal ISO-standard thread cutting. Carrying the IC908 manufacturer grade and a PVD-applied TiAlN coating, this insert is built for demanding threading operations across a wide range of workpiece materials. It features a 1.50mm pitch, right-hand cutting orientation, and a 3/8-inch (0.3750 inch) inscribed circle with a 0.1430-inch thickness. The IC908 substrate combined with the PVD coating process delivers wear resistance and edge toughness suited for production-level threading on CNC lathes and turning centers. Machinists and tooling specialists install this insert as a direct replacement in compatible ISCARTHREAD series toolholders.

This insert is designed for internal threading applications where ISO metric thread profiles at 1.50mm pitch are required. The M chipbreaker geometry supports chip control during internal bore threading on a broad material range. Primary workpiece material compatibility spans universal classifications including steel, stainless, cast iron, non-ferrous, high-temp alloys, and aluminum, as indicated by material codes H, K, M, N, P, and S. It is a fit for job-shop and production environments running ISO-standard internal thread forms on CNC turning equipment.

Key Features

• IC908 grade solid carbide substrate with PVD TiAlN coating for extended tool life
• 1.50mm ISO pitch for metric internal threading applications
• Right-hand cutting orientation with M chipbreaker for controlled chip evacuation
• 3/8-inch inscribed circle — compatible with 16-size ISCARTHREAD internal toolholders
• Universal material compatibility: steel, stainless, cast iron, non-ferrous, high-temp alloys, and aluminum (H, K, M, N, P, S codes)
• Compliant with ISO 13399 cutting tool data representation standards

Compatibility

Designed for use in ISCARTHREAD series 16IRM internal threading toolholders that accept 16-size laydown inserts with a 3/8-inch inscribed circle. Specific compatible holder designations were not provided in available product data — confirm holder acceptance of the 16IRM insert style before ordering.

Installation Notes

Threading inserts of this type are installed and indexed by qualified machinists or tooling technicians on CNC turning centers or manual lathes. Power down and lock out the machine spindle before changing or indexing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure — do not overtighten the clamping screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure full, flat contact and accurate thread form.
