Carrying the NTF3R insert style in the KC850 manufacturer grade, this insert features a CVD-applied TiC\/TiCN\/TiN multilayer finish that enhances wear resistance and extends tool life in demanding threading applications. It covers a partial profile 60-degree thread standard and handles both internal and external threading in a right-hand orientation. The insert size is 3, with a tip-to-top height of 3.58 mm and a corner radius of 0.08 mm. It belongs to the Top Notch series, a widely used system for indexable threading toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on ferrous and non-ferrous materials in both production and job-shop environments. The external pitch range of 0.60 to 2.50 mm (10 to 44 TPI) and internal pitch range of 1.00 to 2.50 mm (9 to 24 TPI) make it appropriate for a broad range of standard thread forms. It is typically installed by CNC machinists and toolroom technicians working on turning applications that require consistent thread geometry and surface finish across high-volume or precision runs.\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 extended wear life\u003c\/li\u003e\n  \u003cli\u003eCovers external pitch 0.60 to 2.50 mm (10 to 44 TPI) and internal pitch 1.00 to 2.50 mm (9 to 24 TPI)\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread standard for right-hand internal and external threading\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility for use with standard NTF-style indexable threading toolholders\u003c\/li\u003e\n  \u003cli\u003eInsert size 3 with 0.08 mm corner radius for precise thread form definition\u003c\/li\u003e\n  \u003cli\u003eMaterial grades C5 and C6 for versatile application across a range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series NTF-style indexable threading toolholders that accept size 3 inserts.

Use the appropriate torx or clamping key specified by the toolholder manufacturer to secure the insert — do not overtighten the clamp screw. Inspect the insert seat and clamping mechanism for chips or debris before seating a new insert. Follow the toolholder manufacturer's recommended speeds and feeds for the KC850 grade when setting up threading passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF3R\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: Partial Profile 60 Degree\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\u003eExternal Pitch Range\u003c\/strong\u003e: 0.60 to 2.50 mm (10 to 44 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range\u003c\/strong\u003e: 1.00 to 2.50 mm (9 to 24 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 3.58 mm (0.1409 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.08 mm (0.0031 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.95 mm (0.1949 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0441 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: 1113807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747780034866,"sku":"1113807","price":243.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80a5a373c0a5f6460c038d06cf39c092.jpg?v=1788885384","url":"https:\/\/voomisupply.com\/products\/kennametal-1113807-threading-insert-ntf3r-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
