It runs at 16 threads per inch (TPI) with a right-hand cutting direction and is ground from solid carbide with an IC250 grade substrate. The IC250 grade carries a PVD-applied TiCN\/TiN coating stack that provides wear resistance and edge toughness on demanding workpiece materials. With a 3\/8-inch (0.375 inches) inscribed circle and a thickness of 0.143 inches, this insert seats in standard 16IR-style toolholders. Licensed machinists and CNC operators performing threading operations on production or job-shop lathes are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal Acme thread applications in residential and commercial machine shop environments. Acme thread forms are common in lead screws, jack screws, power transmission components, and valve stems. The 5902574 is rated for use on cast iron, stainless steel, and steel workpieces, covering the three most common categories encountered in general metalworking and OEM part manufacturing. It is cataloged under the ISCARTHREAD series and conforms to ISO 13399 cutting tool data standards, making it compatible with tool management software that reads ISO 13399 data.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with IC250 grade for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD TiCN\/TiN coating applied for extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e16 TPI Acme thread form for internal right-hand threading\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard 16IR-series toolholders\u003c\/li\u003e\n\u003cli\u003eRated for cast iron, stainless steel, and steel workpieces\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 cutting tool data standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 16IR-style laydown threading insert seats used in internal Acme thread turning operations.

Power down and lock out the machine spindle before seating or removing any insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the insert clamp screw — do not overtighten. Confirm the insert is fully seated in the pocket and that the cutting edge orientation matches the programmed thread direction before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\/TiN, PVD Process\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902574\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738499285298,"sku":"5902574","price":193.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad74c4c269287b06f0d4b264c451a8c_a44ea20b-d362-4b74-a141-3f501e14dc42.jpg?v=1788800313","url":"https:\/\/voomisupply.com\/products\/iscar-5902574-threading-insert-16-tpi-acme-ic250","provider":"Voomi Supply","version":"1.0","type":"link"}
