It carries the GEPI insert style and is manufactured to a Partial Profile 60-degree thread standard, making it suitable for generating internal threads across a range of pitch sizes. The insert is produced from carbide substrate and finished with a PVD-applied IC908 grade coating, which provides wear resistance and thermal stability under continuous cutting conditions. With a cutting tip width of 2.50 mm and a corner radius of 0.05 mm, this insert delivers precise thread geometry. It is used by machinists and toolroom professionals on CNC lathes and threading centers.\u003c\/p\u003e\n\u003cp\u003eThis insert belongs to the Cut Grip and IscarThread series and is intended for internal threading operations on machining centers and turning equipment. The MT chipbreaker geometry controls chip evacuation during threading passes on ferrous and non-ferrous materials. The Partial Profile 60-degree configuration covers a pitch range that includes 0.90 mm and 28 TPI, making it applicable across metric and unified internal thread profiles in production and job-shop environments. It is sold individually but requires a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 grade PVD-coated carbide substrate for extended tool life in internal threading\u003c\/li\u003e\n  \u003cli\u003ePartial Profile 60-degree thread form covers both metric and unified thread standards\u003c\/li\u003e\n  \u003cli\u003eMT chipbreaker promotes reliable chip control during internal threading passes\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.05 mm for accurate thread root geometry\u003c\/li\u003e\n  \u003cli\u003eCutting tip width of 2.50 mm suits fine-pitch internal threading operations\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for toolholders and boring bars that accept the GEPI insert style within the ISCAR Cut Grip and IscarThread series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and all energy sources are locked out before seating or replacing the insert. Use the correct torx or hex key to torque the clamping screw to the toolholder specification without over-torquing the carbide seat. Inspect the insert pocket and seating surface for chips or debris before mounting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GEPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Coated\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: Partial Profile 60 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 0.90 mm \/ 28 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.05 mm (0.0020 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 25MT005\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: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 6403359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51743483265330,"sku":"6403359","price":525.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/433ce728eb3351f6fdd97ca7f74e6f0b.jpg?v=1788847539","url":"https:\/\/voomisupply.com\/products\/iscar-6403359-threading-insert-carbide-ic908-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
