Built to insert style 27ER, it carries ISCAR's IC908 grade with a PVD-applied TiAlN coating, giving it strong wear resistance across a wide range of workpiece materials. The insert is right-hand orientation and fits into compatible 27-series laydown toolholders. With a 15.88 mm (5\/8 inch) inscribed circle and a corner radius of 0.85 mm (0.0330 inches), this insert is dimensionally consistent with ISO 13399 standards. It is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on CNC lathes and turning centers in both job shop and production environments. The IC908 grade with TiAlN finish is rated for universal primary workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials, corresponding to ISO material groups H, K, M, N, P, and S. It fits applications where consistent thread form and tool life are priorities across varied material runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInsert style 27ER for external UN threading at 4 TPI\u003c\/li\u003e\n\u003cli\u003eIC908 carbide grade with PVD TiAlN coating for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003e15.88 mm inscribed circle (5\/8 inch) for precise seating in 27-series holders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.85 mm (0.0330 inches) for accurate thread root profile\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 27ER-style laydown threading toolholders within the ISCARTHREAD series.

Before seating the insert, ensure the toolholder pocket is clean and free of chips or debris that could affect insert positioning. Use the appropriate torx or clamping screw torqued per the toolholder manufacturer's specification. Inspect the thread form on the first part before committing to a full production run.\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 4.00 mm\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: 15.88 mm (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.85 mm (0.0330 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO groups H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5990325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746680471858,"sku":"5990325","price":329.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39287bad1b424273f0d5b3cf20bf3310_f90bf8cc-b2da-4adb-ac3e-46d9ee9cbbd0.jpg?v=1788872616","url":"https:\/\/voomisupply.com\/products\/iscar-5990325-threading-insert-4-tpi-un-ic908-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
