Designated insert style NTF with a left-hand orientation, it cuts partial profile 60-degree threads on both internal and external applications. The KC730 grade targets a broad material grade range of C2, C3, and C4, making it suitable for threading a wide variety of workpiece materials. External pitch range covers 0.60 to 2.50 mm and 10 to 44 TPI. Internal pitch range covers 1.00 to 2.50 mm and 9 to 24 TPI. Licensed machinists and CNC programmers working in production or job-shop environments will recognize this insert as a standard Top Notch-compatible tool.\u003c\/p\u003e\u003cp\u003eThis insert is suited for lathe and turning center threading operations where a partial profile 60-degree thread form is required. It handles both internal and external threading passes in a single insert style, reducing tooling inventory for shops running mixed thread-cutting operations. The left-hand designation means it is intended for left-hand thread cutting or specific toolholder orientations that require a left-hand insert. Typical applications include threading on ferrous and non-ferrous metals across the C2 through C4 material grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD-applied Titanium Nitride (TiN) finish for wear resistance\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form cuts both internal and external threads\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 0.60 to 2.50 mm \/ 10 to 44 TPI\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 1.00 to 2.50 mm \/ 9 to 24 TPI\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for compatible Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eKC730 grade covers material grades C2, C3, and C4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept size 3 NTF-style threading inserts.

Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the Top Notch toolholder to avoid insert rocking or premature failure. Confirm insert hand orientation matches the toolholder hand before beginning any threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF\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: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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\u003c\/strong\u003e: 0.60 to 2.50 mm \/ 10 to 44 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1409 inches \/ 3.58 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0031 inches \/ 0.08 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: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 0.1543 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: 1112943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730510381362,"sku":"1112943","price":227.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab7438b4dd5a50ac04b2da6f0de20db1.jpg?v=1788718739","url":"https:\/\/voomisupply.com\/products\/kennametal-1112943-threading-insert-ntf3l-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
