The insert carries a KCU10 manufacturer grade and features an AlTiN finish applied via PVD coating, which improves wear resistance and thermal stability at the cutting edge. Configured as a right-hand insert with an NDC style geometry, it operates at 11.5 TPI with a 60-degree included angle. This type of insert is used by machinists and tool and die professionals on CNC lathes and manual turning centers where precise thread form and surface finish are required.\u003c\/p\u003e\u003cp\u003eThe 4176165 is suited for NPT threading operations in production and job shop environments. Its right-hand orientation and Top Notch series compatibility make it a direct fit for standard Top Notch toolholders used in residential, commercial, and industrial pipe fitting applications. The insert handles both internal and external NPT thread profiles, making it a versatile option when a single insert geometry needs to cover multiple setups. This part is sold as a single insert; minimum order quantity is 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN finish via PVD coating for enhanced wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eKCU10 carbide grade suited for NPT threading operations\u003c\/li\u003e\n\u003cli\u003e60-degree included angle matches NPT thread form requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for standard CNC and manual lathe setups\u003c\/li\u003e\n\u003cli\u003eHandles both internal and external thread profiles in a single insert style\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert for use with compatible Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept size 3115 inserts.

Power down and lock out the machine before seating or removing the insert. Use the correct torque on the clamping screw per the toolholder manufacturer guidelines and ensure the insert is fully seated with no rocking. Inspect the insert edge condition before each use; a chipped or worn edge will produce out-of-tolerance thread forms.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NDC\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: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\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: NPT\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: 11.5 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: 3115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches (0.1 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.195 inches (4.95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.027 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 4176165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":52036137124146,"sku":"4176165","price":243.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc63a10ca34f477921ced24cd23d0d74.jpg?v=1790023653","url":"https:\/\/voomisupply.com\/products\/kennametal-4176165-threading-insert-kcu10-carbide-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
