Built to the NJ insert style in the Top Notch series, it carries a K68 manufacturer grade with an uncoated bright finish, making it well suited for applications where coating-free cutting edges are preferred for thread form accuracy. The insert cuts right-hand external threads at 16 TPI with a 60-degree included angle conforming to UNJ thread standards. Material grade C3 carbide provides the hardness and wear resistance needed for consistent thread form across production runs.\u003c\/p\u003e\u003cp\u003eThis insert is used in external threading operations on lathes and turning centers, typically in aerospace, military, and high-precision industrial environments where UNJ thread standards are specified. The NJ insert style mounts in compatible Top Notch toolholders. Insert size 3010 governs toolholder selection. It is installed and changed by machinists and CNC operators in job shop and production environments handling precision threaded components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eK68 carbide grade with bright uncoated finish for precise thread form geometry\u003c\/li\u003e\n\u003cli\u003e16 TPI external pitch, 60-degree included angle, UNJ thread standard\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading operations\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0098 inches (0.25 mm) for controlled root profile\u003c\/li\u003e\n\u003cli\u003eTop Notch series NJ insert style for secure, repeatable seating in compatible holders\u003c\/li\u003e\n\u003cli\u003eInsert size 3010 with tip-to-top height of 0.0980 inches for consistent depth reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting NJ-style insert size 3010.

Use the appropriate Torx or insert-clamping wrench specified by the toolholder manufacturer to seat the insert without over-torquing the clamp screw. Verify thread form with a calibrated thread gauge after the first pass. Handle carbide inserts with care to avoid chipping the cutting edge during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NJ\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: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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: 16 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: 3010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0980 inches (2.49 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0098 inches (0.25 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\u003eFinish Coating\u003c\/strong\u003e: Bright \/ Uncoated\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: 0.0243 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: 1113559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739447755058,"sku":"1113559","price":213.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2974fe7a2c6644d2192d0861d6121cd9.jpg?v=1788814708","url":"https:\/\/voomisupply.com\/products\/kennametal-1113559-threading-insert-16-tpi-carbide-k68","provider":"Voomi Supply","version":"1.0","type":"link"}
