Grade IC1008 features a PVD coating applied over a fine-grain carbide substrate, delivering wear resistance and edge stability on a range of workpiece materials including C1 through C3 and C5 through C6 material grades. The insert uses a left-hand cutting orientation and produces a partial profile 60-degree thread form with a 60-degree included angle. Pitch range covers 0.30 to 0.90 mm, equivalent to 28 through 83 TPI, making it suitable for fine-pitch threading work typical in medical, watchmaking, and precision instrument applications.\u003c\/p\u003e\u003cp\u003eThis insert belongs to the IscarThread Swisscut series, engineered for use in Swiss-style screw machines and small-diameter precision turning centers where compact tooling and tight tolerances are required. The MT chipbreaker geometry promotes controlled chip flow in external threading operations. The SCI insert style and size 22 designation match the corresponding ISCAR Swisscut toolholders. Licensed shops performing high-volume threading of small-diameter components will find this insert suited to both roughing and finishing passes within its pitch range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC1008 PVD-coated carbide grade for extended tool life on C1-C3 and C5-C6 materials\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers 0.30-0.90 mm pitch and 28-83 TPI range\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation for Swiss-type and precision turning applications\u003c\/li\u003e\n\u003cli\u003eMT chipbreaker promotes controlled chip evacuation during external threading\u003c\/li\u003e\n\u003cli\u003eSCI insert style, size 22, with 0.03 mm corner radius for fine-pitch accuracy\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 with ISCAR IscarThread Swisscut series toolholders accepting SCI-style, size 22 inserts.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Use the correct torque wrench and ISCAR-specified clamping hardware to seat the insert properly without overtightening. Confirm thread pitch programming in the CNC control matches the insert pitch range before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SCI\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: IC1008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Compatibility\u003c\/strong\u003e: C1, C2, C3, C5, C6\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\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 0.30-0.90 mm \/ 28-83 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.276 inches (7.01 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.0200 inches (0.51 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0010 inches (0.03 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.124 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: IscarThread Swisscut\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: 0.5 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: 6405438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737309577522,"sku":"6405438","price":318.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9818b75eaa0d12226db0eaf0fc0f88d4.jpg?v=1788786921","url":"https:\/\/voomisupply.com\/products\/iscar-6405438-threading-insert-ic1008-28-83-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
