Manufactured in the NTC3L8E geometry within Kennametal's Top Notch series, it carries a PVD-applied TiAlN finish and is graded KC5010 for wear resistance in demanding threading applications. The insert is configured for left-hand thread cutting, making it appropriate for reverse-thread or left-hand-helix applications. With an included angle of 60 degrees, it is suited for standard V-form UN thread profiles. This insert is installed by machinists and CNC tooling technicians in turning and threading operations on metals rated C3 and C4 material grades.\u003c\/p\u003e\u003cp\u003eThe 1799363 is intended for external threading operations on UN-standard workpieces requiring an 8 TPI pitch. The left-hand orientation suits applications where conventional right-hand inserts cannot be used due to thread direction requirements or machine setup constraints. It fits into compatible Top Notch series toolholders and is commonly deployed in production turning environments handling ferrous and non-ferrous metals. The KC5010 grade combined with TiAlN PVD coating provides thermal and abrasion resistance during high-speed threading passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD-applied TiAlN finish for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eKC5010 manufacturer grade rated for C3 and C4 material grades\u003c\/li\u003e\n\u003cli\u003eLeft-hand external threading geometry for reverse-thread applications\u003c\/li\u003e\n\u003cli\u003e8 TPI pitch, 60-degree included angle for UN-standard thread form\u003c\/li\u003e\n\u003cli\u003eNTC insert style within the Top Notch series for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0161 inches (0.41 mm) for controlled thread root profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compatible Top Notch series toolholders accepting NTC3 insert size; verify toolholder specifications against insert size 3 and NTC style before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the toolholder clamping seat is clean and free of chips before installation to prevent seating errors. Follow the toolholder manufacturer's torque guidance for the clamping screw; do not over-tighten.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTC\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: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1071 inches (2.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0161 inches (0.41 mm)\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\u003eWeight\u003c\/strong\u003e: 0.1323 pounds\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: 1799363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742877778226,"sku":"1799363","price":244.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38884c822437cc16aa756672ed4ac741.jpg?v=1788840135","url":"https:\/\/voomisupply.com\/products\/kennametal-1799363-threading-insert-8-tpi-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
