Built from solid carbide with a micrograin substrate and PVD-applied TiAlN\/TiN coating, this insert carries the CP500 manufacturer grade for wear resistance across a broad range of workpiece materials. It cuts right-hand internal threads with a 55-degree included angle and covers a thread pitch range of 48 to 8 TPI, equivalent to 0.50 to 3.00 mm pitch. The 3\/8 inch inscribed circle and 0.1366 inch thickness conform to standard laydown insert geometry in the Snap Tap series. Machinists and CNC operators performing internal threading on steel, stainless, cast iron, and superalloys are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading in both production and job shop environments where a single insert must cover multiple thread pitches. The partial profile geometry allows cutting of thread forms without full root control, making it versatile across ISO-standard thread families. The A2 chipbreaker promotes chip evacuation in blind-bore and through-bore threading applications. Compatible workpiece material classifications include ISO material groups K, M, P, and S, covering gray cast iron, stainless steel, carbon and alloy steels, and high-temperature superalloys. Applications range from threading hydraulic fittings and fluid power components to general precision machined parts requiring internal thread forms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate with PVD TiAlN\/TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eCP500 grade rated for universal workpiece materials across ISO groups K, M, P, and S\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle partial profile cuts a wide range of ISO-standard internal thread forms\u003c\/li\u003e\n  \u003cli\u003eThread pitch coverage from 48 to 8 TPI (0.50 to 3.00 mm) in a single insert\u003c\/li\u003e\n  \u003cli\u003eA2 chipbreaker geometry supports chip control in internal bore threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation; 0.0030 inch corner radius minimizes stress at thread root\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 00078013 is an insert in the SECO Snap Tap series with insert style designation 16NR, conforming to ISO standard laydown threading insert geometry.

Ensure the machine spindle is fully stopped and the turret is indexed away from the work zone before replacing inserts. Use the correct insert-seating torque per the toolholder manufacturer specification and confirm the insert is fully seated with no rocking before resuming cutting. Verify thread pitch programming matches the insert TPI range before initiating the threading cycle.\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 Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\/TiN, PVD Process\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand Internal Partial Profile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 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 (mm)\u003c\/strong\u003e: 0.50 to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0430 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\u003eChipbreaker\u003c\/strong\u003e: A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials (ISO)\u003c\/strong\u003e: K, M, P, S\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: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\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: 00078013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563672338738,"sku":"00078013","price":83.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d357ffdbd2831e2c251c1db64f09dd2.jpg?v=1786500897","url":"https:\/\/voomisupply.com\/products\/seco-00078013-threading-insert-55-degree-3-8-inch-ic-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
