Designated by ISO code LT16ER18UNCB, this insert features a right-hand cutting orientation and a TiAlN coating applied via PVD process, which improves wear resistance and tool life at elevated cutting temperatures. The KC5010 grade is engineered for threading operations on steel, stainless steel, cast iron, superalloys, and titanium. With an inscribed circle of 3\/8 inches and a thickness of 0.1430 inches (3.44 mm), this insert fits standard ER-style laydown threading toolholders used in CNC turning and threading applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading on turned components across residential, commercial, and industrial machining environments. It is installed in compatible ER-style laydown insert toolholders on CNC lathes and turning centers. The 18 TPI UN thread form makes it appropriate for producing standard Unified National thread profiles on a range of workpiece materials including steel alloys and titanium-based superalloys. Machinists and toolroom technicians working with precision thread-turned parts will find this insert applicable to both production and maintenance machining contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD-applied TiAlN coating for extended tool life in abrasive and high-temperature cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand external UN thread form at 18 TPI for standard Unified National thread production\u003c\/li\u003e\n\u003cli\u003eKC5010 manufacturer grade rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eER insert style in size code 16 with 3\/8-inch inscribed circle for precise toolholder seating\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker geometry for controlled chip evacuation during threading passes\u003c\/li\u003e\n\u003cli\u003eInsert thickness of 0.1430 inches (3.44 mm) and hole diameter of 0.1551 inches for secure clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement laydown threading insert for ER-style size 16 threading toolholders compatible with external UN thread applications at 18 TPI.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of carbide threading inserts should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before removing or seating the insert. Use the correct torque driver or clamp screw tool specified by the toolholder manufacturer to secure the insert  -  do not overtighten by hand or with unapproved tools. Verify thread form, TPI, and hand orientation against the workpiece drawing before initiating the threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER18UNCB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ER\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\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: 18 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: CB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches (3.44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inches (3.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1712603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740165144882,"sku":"1712603","price":617.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80ee15cf173a23aac9eb3b5eddbba00c.jpg?v=1788823078","url":"https:\/\/voomisupply.com\/products\/kennametal-1712603-threading-insert-18-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
