Coated with TiAlN via a PVD process under the IC908 manufacturer grade, this insert delivers wear resistance and thermal stability in demanding threading operations. It carries a 3\/8-inch (0.375 inch decimal) inscribed circle and a thickness of 0.143 inches. The IC908 grade is suited to a broad range of workpiece materials including steels, stainless, cast iron, nonferrous alloys, and high-temperature alloys. Licensed machinists and CNC turning specialists are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal UN thread-form operations in turning centers and CNC lathes equipped with compatible 16IR-style toolholders. Its universal primary workpiece material rating makes it applicable across production and job-shop environments handling carbon steel, alloy steel, stainless steel, cast iron, nonferrous, and superalloy workpieces. The M chipbreaker designation is suited to medium cutting conditions. Typical applications include threading bores, nuts, fittings, and similar internally threaded components in both high-volume production and maintenance machining contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 PVD TiAlN-coated solid carbide grade for extended tool life across multiple workpiece material families\u003c\/li\u003e\n\u003cli\u003e16 TPI UN internal thread form, right-hand cut\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle (0.375 inch) for use in standard 16IR-series toolholders\u003c\/li\u003e\n\u003cli\u003e0.143-inch insert thickness for secure, stable seating in laydown-style pockets\u003c\/li\u003e\n\u003cli\u003eM chipbreaker optimized for medium-condition internal threading passes\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data representation standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16IR-series laydown threading toolholders accepting a 3\/8-inch inscribed circle insert.

Use the toolholder manufacturer's specified torx or hex key to achieve proper clamp torque without over-tightening, which can fracture the carbide substrate. Inspect the insert pocket and clamp for chips or debris before seating the insert. Always index or replace the insert before chipping propagates to the toolholder pocket.\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: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlN, PVD Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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\u003eChipbreaker\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inch decimal \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 5901580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755789877554,"sku":"5901580","price":150.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/987ab2a8cf2799be2ce998378a0af126.jpg?v=1788959718","url":"https:\/\/voomisupply.com\/products\/iscar-5901580-laydown-threading-insert-16-un-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
