Iscar 5902263 Threading Insert 10 Tpi 3/8 in IC908

Product Description

The ISCAR 5902263 is a solid carbide laydown threading insert designed for external American Buttress thread forms on CNC lathes and turning centers. Running the IC908 manufacturer grade with a PVD-applied TiAlN coating, this insert handles a broad range of workpiece materials including steel, cast iron, stainless, non-ferrous, and high-temperature alloys. It cuts at 10 threads per inch (TPI) with a right-hand orientation, a 3/8 inch (0.3750 inch decimal) inscribed circle, and a 0.1430 inch thickness. The insert seats in the laydown position and is intended for use by machinists and CNC toolroom technicians requiring consistent buttress thread profiles.

This insert is suited for production and job-shop turning operations where external American Buttress threads are required. Buttress threads are common in high-load unidirectional applications such as hydraulic cylinders, vise screws, and heavy mechanical assemblies. The IC908 grade with PVD TiAlN finish is engineered for universal material compatibility, covering material codes H, K, M, N, P, and S per ISO 13399 classification. Minimum order quantity is 5 inserts; each package contains 1 insert.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the machine powered off and the spindle locked before insert exchange. Use the correct torx or hex key specified for the toolholder clamp to seat the insert securely without over-torquing the clamping screw. Verify thread form and TPI match the part print before running the first part. Inspect the insert seating pocket for chips or debris that could affect insert registration and thread accuracy.
