Iscar 5902315 Laydown Threading Insert 14 Tpi Nptf

Product Description

The ISCAR 5902315 is a solid carbide laydown threading insert designed for cutting external NPTF threads on CNC lathes and turning centers. Manufactured under the ISCARTHREAD series in grade IC908 with a PVD-applied TiAlN coating, this insert delivers thermal resistance and edge wear performance across a broad range of workpiece materials. It is configured for right-hand threading at 14 threads per inch with a 3/8-inch inscribed circle and a nominal thickness of 0.143 inches. Machinists and CNC operators in production and job-shop environments install this insert when threading pipe-standard tapered fittings to NPTF specifications.

This insert is suited for external NPTF tapered pipe thread applications in both production turning and maintenance machining contexts. The IC908 grade with PVD TiAlN coating supports use across universal workpiece material classes, including steels, stainless steels, cast irons, non-ferrous alloys, and heat-resistant superalloys, corresponding to ISO material codes H, K, M, N, P, and S. It is a single-use laydown-style insert seated in compatible ISCARTHREAD external toolholders designed for the 16ER insert size code.

Installation Notes

Installation is performed by CNC machinists and lathe operators. Power down and lock out the machine before seating or changing inserts. Use the appropriate torx or clamping screw driver specified for the toolholder to secure the insert without over-torquing the clamp. Confirm insert orientation and thread hand before resuming cutting operations.
