Manufactured to the NJP insert style in the Top Notch series, this insert carries the KC850 grade — a CVD-coated carbide with a TiC\/TiCN\/TiN multilayer finish suited for steel and stainless threading applications in the C5 and C6 material grade range. It cuts right-hand external threads to the UNJ standard at 12 TPI with a 60-degree included angle. The corner radius measures 0.013 decimal inches and tip-to-top height is 0.098 decimal inches, making precise seating in a compatible Top Notch holder essential for on-spec thread form.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision external threading of aerospace and industrial fastener profiles where the UNJ thread form — with its controlled root radius — is specified. Typical applications include turning of alloy steel and stainless components on CNC lathes in job shop, production, and aerospace manufacturing environments. The KC850 CVD coating provides wear resistance and edge stability during interrupted or continuous threading passes at moderate to high cutting speeds. Machinists and CNC programmers working to UNJ specifications will recognize the NJP3014R12 designation as the insert geometry and size code within the Top Notch platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 carbide grade with CVD-applied TiC\/TiCN\/TiN multilayer coating for wear resistance in steel threading\u003c\/li\u003e\n  \u003cli\u003e12 TPI external thread pitch to UNJ thread standard with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard CNC lathe external threading passes\u003c\/li\u003e\n  \u003cli\u003eNJP insert style in the Top Notch series — compatible with Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.013 decimal inches (0.33 mm) for controlled UNJ root form\u003c\/li\u003e\n  \u003cli\u003eC5 and C6 material grade classification, suitable for steel and stainless threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series external threading toolholders that accept the NJP3014R12 insert size and style.

Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and clamping screw specified for the Top Notch holder to ensure proper insert retention — do not overtighten by hand. Inspect the insert pocket and clamping surfaces for chips or debris before seating to prevent insert rocking and thread-form error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NJP\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: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNJ\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 12 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: 3014\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiC\/TiCN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.098 inches (2.49 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.013 inches (0.33 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: 0.0218 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: 1114948\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736276697394,"sku":"1114948","price":254.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0e6a234cb4602de6e1d1d5b080f82b6.jpg?v=1788776942","url":"https:\/\/voomisupply.com\/products\/kennametal-1114948-threading-insert-njp3014r12-kc850-12-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
