Running at 8 threads per inch with a right-hand orientation, this insert seats in standard LT16ER-style toolholders and is suited for oil country and industrial threading applications. The KC5025 grade substrate is paired with a PVD-applied TiAlN coating, providing resistance to heat and wear during intermittent or continuous threading passes. The 3\/8-inch inscribed circle and 0.1430-inch thickness conform to standard 16ER insert geometry, making it a direct fit for compatible tooling systems on CNC lathes and threading machines.\u003c\/p\u003e\u003cp\u003eThis insert is applied in external threading of pipe and coupling stock conforming to API Round thread specifications. Typical installations include oilfield tubular goods machining, coupling threading, and similar applications where API Round thread form accuracy is critical. Licensed machinists and CNC turning operators in oil and gas, energy, and heavy industrial shops are the primary users. The TiAlN coating supports performance in both dry and minimal-quantity-lubrication cutting environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in KC5025 PVD-coated grade for extended tool life\u003c\/li\u003e\n\u003cli\u003eTiAlN coating applied via PVD process for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand external API Round thread form at 8 TPI\u003c\/li\u003e\n\u003cli\u003e16ER insert style with 3\/8-inch inscribed circle for standard toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e0.1430-inch thickness conforms to laydown insert seating requirements\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1551 inches for secure mechanical clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT16ER-style external threading toolholders configured for API Round thread form inserts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or tooling setup personnel. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before seating or replacing the insert. Verify insert orientation and thread hand match the toolholder and programmed cutting direction before resuming operation. Follow the toolholder manufacturer torque guidance for the clamping screw to prevent insert movement or damage to the carbide.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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: API Round\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\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\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\u003eWeight\u003c\/strong\u003e: 0.0095 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1743799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731003408690,"sku":"1743799","price":617.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3da7620a17375c747d4efb4a917f657.jpg?v=1788725712","url":"https:\/\/voomisupply.com\/products\/kennametal-1743799-threading-insert-8-tpi-api-round-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
