Manufactured in the Top Notch series, it carries a TiAlN finish applied via PVD coating process and is offered in manufacturer grade KC5010 with a material grade of C3\/C4. The insert profiles American Buttress threads with an included angle of 45 degrees, covering an internal pitch range of 8-16 TPI. Its left-hand orientation and compact geometry make it suited for both internal and external threading applications where tight tolerances and extended tool life are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metal cutting environments where American Buttress thread forms are required, commonly found in oil and gas, heavy equipment, and industrial machinery components. The left-hand configuration is specified for applications where thread direction demands a left-hand cutting approach. It is installed and operated by machinists and CNC tool setup technicians working with Top Notch-compatible toolholders. The TiAlN PVD coating provides thermal resistance and wear protection during high-speed threading passes on ferrous and alloy workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with TiAlN PVD finish for extended wear resistance in threading applications\u003c\/li\u003e\n  \u003cli\u003eAmerican Buttress thread standard with 45-degree included angle for accurate thread form profiling\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for left-hand threading operations\u003c\/li\u003e\n  \u003cli\u003eCovers 8-16 TPI internal pitch range for versatile buttress thread production\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style NTB for use with compatible Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eCompact insert size 3 with a thickness of 0.1949 inches and corner radius of 0.0065 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NTB-style threading inserts.

The machine spindle must be stopped and all energy sources locked out before seating or replacing the insert in the toolholder. Ensure the insert pocket is clean and free of chips before clamping to maintain proper seating and thread form accuracy. Confirm correct insert hand orientation and toolholder compatibility before beginning a threading pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\/C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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 Standard\u003c\/strong\u003e: American Buttress\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 8-16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1949 inches (4.95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0065 inches (0.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0122 inches (0.31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0319 pounds\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: 1799589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730965659954,"sku":"1799589","price":240.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d56a401b6a8cc914a8db5c04cbc5a4a.jpg?v=1788725402","url":"https:\/\/voomisupply.com\/products\/kennametal-1799589-threading-insert-ntb3lb-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
