Coated with Titanium Nitride (TiN) via a PVD process, the KC730 grade insert handles a partial profile 60-degree thread standard. It covers an external pitch range of 2.50 to 4.00 mm (6 to 11 TPI) and an internal pitch of 4.00 mm (6 TPI). The NT3RC style is right-hand orientation with an insert size of 3. Tip to top of insert measures 0.098 inches (2.46 mm), with a corner radius of 0.0134 inches (0.34 mm) and a thickness of 0.1949 inches (4.95 mm). This insert is used by machinists and toolroom technicians on CNC lathes and manual turning centers.\u003c\/p\u003e\u003cp\u003eThe 1112904 threading insert suits ferrous and non-ferrous threading applications where a partial profile 60-degree form is required. The KC730 carbide grade with TiN PVD coating is well suited for general-purpose threading on steels and cast irons classified under material grades C2, C3, and C4. Right-hand cutting geometry makes it appropriate for conventional feed-direction threading passes on both OD and ID thread forms. It is a single insert sold as part of the Top Notch modular tooling system, which uses a dedicated holder platform for indexable threading operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with Titanium Nitride (TiN) PVD finish for wear resistance on steel threading\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers a range of standard thread pitches without profile grinding\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 2.50 to 4.00 mm (6 to 11 TPI); internal pitch: 4.00 mm (6 TPI)\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation, NT style, insert size 3\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0134 inches (0.34 mm) for consistent thread root geometry\u003c\/li\u003e\n\u003cli\u003eCompatible with Top Notch series toolholders for quick indexing and secure insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept NT3RC style inserts.

Power down and de-energize the machine spindle before seating or replacing the insert. Use the appropriate Top Notch torx or clamping key to secure the insert to the recommended clamping torque specified in the toolholder documentation. Inspect the insert pocket and clamping mechanism for chips or damage before indexing to a fresh edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT3RC\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 2.50 to 4.00 mm (6 to 11 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 4.00 mm (6 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: 0.098 inches (2.46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0134 inches (0.34 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: 0.0214 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: 1112904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736379031858,"sku":"1112904","price":219.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5f9323c8190a3a3a1ddb919599fa9fa.jpg?v=1788777588","url":"https:\/\/voomisupply.com\/products\/kennametal-1112904-threading-insert-nt3rc-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
