It carries the ISO designation LT16ER8ACME and is finished with a PVD-applied TiAlN coating that increases surface hardness and heat resistance under continuous threading loads. The insert is right-hand oriented and features a 3\/8-inch (9.53 mm) inscribed circle with a thickness of 0.143 inches (3.44 mm). Grade KC5025 is a coated carbide grade engineered for threading in steel, stainless steel, cast iron, superalloys, and titanium. Licensed machinists and CNC lathe operators working in production or maintenance environments are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external Acme thread applications on lathes and turning centers in both production machining and job shop environments. The Acme thread form is commonly found on lead screws, power transmission components, and linear actuator hardware. The LT16ER size designation corresponds to the ER insert style and a size code of 16, making it compatible with standard LT16 threading toolholders. The TiAlN coating extends tool life when threading work-hardened and abrasion-resistant materials including stainless steel and superalloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e8 TPI Acme external thread profile, ISO code LT16ER8ACME\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading operations\u003c\/li\u003e\n\u003cli\u003eKC5025 grade rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 0.143-inch thickness for secure seating in LT16 pockets\u003c\/li\u003e\n\u003cli\u003eCutting edge to theoretical edge length of 0.0550 inches; face of insert to tip centerline of 0.0590 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT16 ER-style laydown threading toolholders.

Use the appropriate torx or hex key as specified by the toolholder manufacturer to seat the insert clamp to the correct engagement — do not overtighten by feel alone. Inspect the insert pocket for chips or debris before seating the new insert. Verify thread form with a thread gauge on the first part after any insert change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER8ACME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 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: 3\/8 inch (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: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0106 pounds\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: 10\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: 1743780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753911025970,"sku":"1743780","price":620.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a10ebaa04ccf454aa7c504367ced9ee8.jpg?v=1788941995","url":"https:\/\/voomisupply.com\/products\/kennametal-1743780-threading-insert-8-tpi-acme-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
