Manufactured from solid carbide in an uncoated bright finish, it carries the H15 grade designation and belongs to the Snap Tap series. This insert produces a partial profile 60-degree included angle thread and covers a pitch range of 0.50 mm to 3.00 mm, equivalent to 48 to 8 TPI. With an inscribed circle of 0.3752 inches and a thickness of 0.1366 inches, it seats into compatible 16NR-style toolholders used on CNC lathes and threading machines. Machinists and toolroom technicians specify this insert for precision internal threading across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading applications in both production and job-shop environments. It is applied when cutting unified, metric, or AG60 thread forms in cast iron, non-ferrous metals, and stainless steel workpieces. The solid carbide construction and H15 grade make it appropriate for moderate to interrupted cutting conditions typical of small-bore internal threading on CNC turning centers and manual lathes with threading capability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, uncoated bright finish for consistent dimensional performance\u003c\/li\u003e\n  \u003cli\u003eH15 grade designation suited for cast iron, non-ferrous metals, and stainless steel\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle, right-hand internal partial profile thread form\u003c\/li\u003e\n  \u003cli\u003ePitch range 0.50 mm to 3.00 mm (48 to 8 TPI) covers a wide range of common thread sizes\u003c\/li\u003e\n  \u003cli\u003e16NR insert style with 9.53 mm inscribed circle for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO standards for interchangeability in standardized tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 16NR-style laydown threading insert seats in Snap Tap series toolholders and other ISO-compatible internal threading holders accepting the 16NR insert style.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis insert is installed by a machinist or toolroom technician into a compatible 16NR-style threading toolholder. The machine spindle must be brought to a full stop and the toolholder secured in the turret before seating or replacing the insert. Use the correct torque key or clamping screw specified by the toolholder manufacturer to secure the insert without over-torquing the clamp screw. Inspect the insert pocket for chips or debris before seating to ensure proper contact and repeatable thread geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NR\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: H15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 48 to 8 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50 mm to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.3752 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.47 mm (0.1366 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron; Non-Ferrous Metal; Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 2\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74027528\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559014170930,"sku":"74027528","price":85.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8f43eb2b300626e5afd193d31a75078.jpg?v=1786425787","url":"https:\/\/voomisupply.com\/products\/seco-74027528-threading-insert-16nr-ag60-h15-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
