It carries the KC730 manufacturer grade with a Titanium Nitride (TiN) finish applied via PVD coating, which improves surface hardness and wear resistance during thread-cutting operations. The insert is left-hand oriented, suited for 4 TPI Acme thread profiles with a 29-degree included angle. It belongs to the Top Notch series and is sized at Insert Size 3. Machinists and CNC operators working on lathes and threading centers use this insert for Acme-threaded components such as lead screws, jacks, and actuators.\u003c\/p\u003e\u003cp\u003eThis insert fits internal and external Acme thread applications at 4 TPI. The left-hand configuration makes it appropriate for left-hand lead screws and similar components where standard right-hand inserts cannot be used. The KC730 grade with PVD TiN coating performs well in C2, C3, and C4 material grades, covering a range of cast iron, non-ferrous, and general-purpose turning applications. The Top Notch series provides consistent seating and indexing in compatible toolholders. This insert is sold individually but is subject to a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eLeft-hand Acme thread profile at 4 TPI with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eCuts both internal and external threads in a single insert style\u003c\/li\u003e\n\u003cli\u003eInsert Size 3 in the Top Notch series for reliable toolholder registration\u003c\/li\u003e\n\u003cli\u003eCompatible with C2, C3, and C4 material grades\u003c\/li\u003e\n\u003cli\u003eTip to top of insert measures 0.1331 inches (3.38 mm); thickness 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for Top Notch series toolholders accepting NA-style, Size 3 inserts for Acme internal and external threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and indexed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torx or clamping key specified by the toolholder manufacturer to seat the insert firmly — do not overtighten by hand estimation. Inspect the seating pocket for chips or debris before installing a fresh insert to ensure full contact and accurate thread geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NA3L4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\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\u003eThread Standard\u003c\/strong\u003e: Acme\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\u003eInternal Pitch\u003c\/strong\u003e: 4 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1331 inches (3.38 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: 0.0313 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 1112926\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728208855346,"sku":"1112926","price":208.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/803c234b40b74c0248511fcea26c01a3.jpg?v=1788689575","url":"https:\/\/voomisupply.com\/products\/kennametal-1112926-threading-insert-carbide-kc730-acme-4-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
