The insert features an IC908 manufacturer grade substrate with a PVD-applied TiAlN coating, delivering wear resistance and thermal stability across a broad range of workpiece materials. With a 5\/8 inch (0.6250 inch) inscribed circle and a 0.251 inch thickness, this is a right-hand insert built to the 27ER style for use in compatible ISCARTHREAD toolholders. It is suited for machinists and tooling specialists working on oilfield and pipeline components requiring precise API thread profiles.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading operations conforming to API thread standards, commonly encountered in oil and gas fabrication, pipe coupling work, and related industrial machining environments. The IC908 grade is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S, making it adaptable across steels, stainless alloys, cast irons, non-ferrous metals, high-temperature alloys, and similar materials. It is packaged individually and sold in single-unit quantities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 grade solid carbide substrate with PVD TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand external thread orientation for standard API threading applications\u003c\/li\u003e\n\u003cli\u003e4 TPI thread pitch for API-spec pipe and coupling profiles\u003c\/li\u003e\n\u003cli\u003e5\/8 inch inscribed circle (0.6250 inch) with 0.0382 inch corner radius\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across H, K, M, N, P, and S workpiece material codes\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for ISCARTHREAD series external threading toolholders accepting the 27ER insert style.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully in the toolholder pocket and confirm the clamping screw torque is appropriate per the toolholder manufacturer specification. Inspect the insert seat and clamping components for wear or debris before installation to avoid seating errors that affect thread accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 27ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 27\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 Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: API\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4 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: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0382 inch (0.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2510 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\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: 0.265 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: 5902369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750141362482,"sku":"5902369","price":82.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39287bad1b424273f0d5b3cf20bf3310_1c2afe71-0f5e-43be-9459-749801245f0e.jpg?v=1788913795","url":"https:\/\/voomisupply.com\/products\/iscar-5902369-laydown-threading-insert-4-tpi-api-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
