Manufactured from solid carbide in the KC5010 grade with a PVD-applied TiAlN coating, this insert delivers hardness and heat resistance suited for high-speed threading operations. It is configured for right-hand external threading at 28 threads per inch (TPI) with a 3\/8-inch inscribed circle and a thickness of 0.1430 inches (3.44 mm). The ISO designation LT16ER28UNCB reflects the ER insert style, size code 16, and CB chipbreaker geometry. Machinists and CNC tooling specialists install this insert as a replaceable cutting element in compatible laydown threading toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on steel, stainless steel, cast iron, superalloys, and titanium workpieces, corresponding to ISO material codes P, M, K, and S. It is intended for external UN thread production at 28 TPI in precision turning environments, including job shops, production machining facilities, and maintenance repair operations where UN-threaded components are manufactured or refurbished. The CB chipbreaker geometry aids chip control during threading passes on these material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5010 solid carbide grade with PVD TiAlN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread profile at 28 TPI\u003c\/li\u003e\n  \u003cli\u003eER insert style, size code 16, with CB chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (9.53 mm) inscribed circle; thickness 0.1430 inches (3.44 mm)\u003c\/li\u003e\n  \u003cli\u003eHole diameter 0.1551 inches (3.94 mm) for secure laydown toolholder seating\u003c\/li\u003e\n  \u003cli\u003eCompatible with ISO material groups P, M, K, and S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement laydown threading insert for toolholders accepting ER-style size 16 inserts in external UN threading applications.

Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully against the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification using a calibrated torque driver. Inspect the seating pocket for chips or debris before clamping to avoid insert rocking or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eISO Designation\u003c\/strong\u003e: LT16ER28UNCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\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 Type\u003c\/strong\u003e: External UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 28 TPI\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 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: 0.0280 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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and 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: 0.0115 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 5)\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1712609\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743830180146,"sku":"1712609","price":317.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac1f3020b09faf262d683c7b828b8a47.jpg?v=1788850141","url":"https:\/\/voomisupply.com\/products\/kennametal-1712609-threading-insert-28-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
