Manufactured in the Top Notch series with a KC850 grade carbide substrate, this insert features a CVD-applied TiC\/TiCN\/TiN multilayer finish that improves wear resistance and extends tool life in steel and cast iron applications. The insert is right-hand orientation, sized at Insert Size 3, and carries a 6 TPI internal pitch with a 29-degree included angle. It is installed and changed by machinists and CNC lathe operators working in precision threading operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for Acme thread-form applications in both internal and external threading operations on CNC and manual lathes. The KC850 grade performs well in continuous and light interrupted cuts on carbon steels, alloy steels, and cast irons classified under material grades C5 and C6. The Top Notch insert system uses a notch-style clamping mechanism that allows quick, repeatable insert indexing without additional tools in most compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 carbide grade with CVD TiC\/TiCN\/TiN multilayer coating for extended wear life\u003c\/li\u003e\n  \u003cli\u003eAcme thread form, 29-degree included angle, 6 TPI pitch\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard lathe threading passes\u003c\/li\u003e\n  \u003cli\u003eSuitable for both internal and external thread cutting\u003c\/li\u003e\n  \u003cli\u003eTop Notch series notch-lock clamping for fast, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.005 decimal inches for controlled thread root form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series threading toolholders that accept Size 3 inserts.

Ensure the machine spindle is fully stopped and the toolholder is secured before changing inserts. Seat the insert firmly into the Top Notch pocket until the notch engages the clamp fully  -  an improperly seated insert can fracture under cutting loads. Verify insert hand orientation and thread form against the job drawing before beginning a 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: NA3R6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiC\/TiCN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Acme\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 6 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 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: 0.1492 inches (3.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.0567 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\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: 0.0214 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1113799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":52015500853554,"sku":"1113799","price":255.24,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fc46ee5e44e1148e2d30cf707877e03.jpg?v=1790007866","url":"https:\/\/voomisupply.com\/products\/kennametal-1113799-threading-insert-kc850-carbide-6-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
