Built from solid carbide with a TiC\/TiN coating, it delivers hard, wear-resistant cutting edges suited to steel, stainless, and cast iron workpieces. The insert profiles at 11.5 threads per inch, matching the NPT standard taper thread pitch used on pipe fittings and valves. It carries an inscribed circle of 0.375 inches and a thickness of 0.146 inches, fitting standard 16ER toolholders. The HG630TR grade provides a balance of toughness and heat resistance for interrupted and continuous threading passes.\u003c\/p\u003e\u003cp\u003eThis insert is used in production and job-shop turning operations where internal NPT pipe threads are required. Typical applications include threading pipe couplings, valve bodies, hydraulic fittings, and manifold ports. The right-hand cutting geometry suits standard lathe rotation for internal threading cycles. Machinists, CNC operators, and tool-and-die professionals working with pipe-thread components are the primary users. Sold individually per package with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for wear resistance in ferrous and non-ferrous threading\u003c\/li\u003e\n\u003cli\u003eTiC\/TiN multilayer coating reduces heat buildup and extends edge life\u003c\/li\u003e\n\u003cli\u003e11.5 TPI pitch matches NPT pipe thread standard\u003c\/li\u003e\n\u003cli\u003eRight-hand internal threading geometry for standard boring-bar setups\u003c\/li\u003e\n\u003cli\u003e16ER insert style fits a wide range of compatible laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003eRelief angle of 0 degrees provides full-profile thread form support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders configured for internal NPT thread applications at 11.5 TPI.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC operators following standard insert-seating procedures for laydown threading toolholders. Ensure the machine spindle is at a complete stop before changing inserts, and use the correct torx or clamp screw torque per the toolholder manufacturer's specification. Verify insert seating and clamp engagement before running the threading cycle. Always confirm thread pitch and taper compliance with a calibrated NPT thread gauge after cutting.\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: HG630TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 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: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08715161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733018837298,"sku":"H08715161","price":266.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7f6aa2af64538297fed169963dfaabf.jpg?v=1788750549","url":"https:\/\/voomisupply.com\/products\/hertel-h08715161-threading-insert-11-5-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
