Manufactured in the KC850 grade with a CVD-applied TiC\/TiCN\/TiN multilayer finish, this insert handles a broad pitch range: 1.25 to 4.00 mm (6 to 20 TPI) for external threads and 2.00 to 5.00 mm (5 to 12 TPI) for internal threads. The partial profile 60-degree included angle makes it suitable for a wide range of thread forms without requiring a dedicated insert for each pitch. It is a left-hand insert in the Top Notch series, sized at Insert Size 3. Machinists and CNC operators in precision manufacturing and metalworking environments install this insert on compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning center and lathe applications where both internal and external threading passes are required. The partial profile geometry allows a single insert to cut multiple pitches within its rated range, reducing tooling inventory. The KC850 carbide grade with CVD coating provides wear resistance and thermal stability suited for threading steel and alloy workpieces. It is appropriate for production threading in job shop and industrial manufacturing settings where consistent thread quality and insert life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 carbide grade with CVD TiC\/TiCN\/TiN multilayer coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree included angle cuts multiple pitches without dedicated per-pitch tooling\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 1.25 to 4.00 mm (6 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 2.00 to 5.00 mm (5 to 12 TPI)\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation in the Top Notch series\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.17 mm (0.0065 inches) for controlled thread root form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders compatible with Insert Size 3 left-hand inserts.

Power down and lock out the machine before seating or removing inserts. Use the correct torque wrench and clamping screw specified for the Top Notch toolholder to avoid insert movement or breakage during threading passes. Do not exceed the pitch range stated for this insert, as out-of-range use will damage the cutting edge and produce non-conforming threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTP\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\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: 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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch Range\u003c\/strong\u003e: 1.25 to 4.00 mm (6 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range\u003c\/strong\u003e: 2.00 to 5.00 mm (5 to 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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 2.49 mm (0.0980 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.17 mm (0.0065 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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0235 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: 1113816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51775004180786,"sku":"1113816","price":244.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b669edbd1fdc61e3e027875d8782d0b3.jpg?v=1789166129","url":"https:\/\/voomisupply.com\/products\/kennametal-1113816-threading-insert-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
