Manufactured in the NTP3L style and produced in the K68 carbide grade with a bright, uncoated finish, this insert is engineered for the Top Notch series tooling system. It cuts a partial profile 60-degree thread form and is suited for left-hand thread applications. The insert handles external pitches from 1.25 to 4.00 mm (6 to 20 TPI) and internal pitches from 2.00 to 5.00 mm (5 to 12 TPI). A corner radius of 0.17 mm (0.0065 inches) contributes to consistent thread geometry across production runs.\u003c\/p\u003e\u003cp\u003eThis insert is appropriate for threading operations in both turning centers and manual lathes where left-hand thread profiles are required. Typical applications include production threading of external fastener forms and internal thread forms on workpieces requiring 60-degree partial profile geometry. The uncoated K68 carbide grade performs in a range of workpiece materials classified under material grade C3, making it a suitable choice in job shop and production environments where thread accuracy and insert consistency are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide construction, K68 grade, uncoated bright finish for direct visual wear monitoring\u003c\/li\u003e\n\u003cli\u003eCuts partial profile 60-degree thread forms on both internal and external threads\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert style (NTP3L) for left-hand thread applications\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\u003eTop Notch series compatibility for repeatable indexing and seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series threading toolholders that accept size 3 NTP-style inserts.

Power down and lock out the machine spindle before removing or seating any insert. Use the appropriate Torx or clamping key specified for the Top Notch toolholder to avoid overtightening, which can fracture the carbide. Inspect the insert pocket for chips or debris before seating each new insert to ensure proper support and thread accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTP3L\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: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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: 0.024 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1113511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740045967666,"sku":"1113511","price":212.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe7836d24758abcf7de6790b4f4ff4bc.jpg?v=1788821794","url":"https:\/\/voomisupply.com\/products\/kennametal-1113511-threading-insert-ntp3l-k68-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
