Manufactured to the NT3LCK geometry, it carries a PVD-applied TiAlN finish that improves heat resistance and wear life at higher cutting speeds. The insert covers a partial profile 60-degree thread standard, handling external pitches from 2.50 to 4.00 mm (6 to 11 TPI) and an internal pitch of 4.00 mm (6 TPI). At 0.1949 inches (4.95 mm) thick with a corner radius of 0.0134 inches (0.34 mm), it is a left-hand insert suited for right-to-left threading passes. Machinists and CNC operators in production and job-shop environments install and replace these inserts during scheduled tooling changes.\u003c\/p\u003e\u003cp\u003eThis insert fits threading applications in general machining environments where ISO material grades C3 and C4 workpiece materials are common, including cast irons and hardened steels. The K-style chipbreaker geometry is intended for threading passes where chip control is critical to surface finish and thread integrity. It is well suited for moderate to high production runs on lathes equipped with a Top Notch-compatible toolholder system. Both external and internal threading operations fall within its designed application range, making it a versatile insert for shops running mixed threading work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD TiAlN coating improves wear resistance and thermal stability at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers external pitches 2.50 to 4.00 mm (6 to 11 TPI)\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert geometry for right-to-left threading passes\u003c\/li\u003e\n\u003cli\u003eK-style chipbreaker supports controlled chip evacuation during threading\u003c\/li\u003e\n\u003cli\u003eCarbide substrate with KC5010 manufacturer grade balances toughness and hardness\u003c\/li\u003e\n\u003cli\u003eCompatible with both internal and external threading operations in a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for Top Notch series threading toolholders accepting NT insert size 3 geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts are installed and replaced by machinists or CNC tooling technicians following machine-specific lockout and toolholder torque procedures. Power down or place the machine in a safe state before accessing the turret or toolholder. Use the correct torque wrench and seating screw specified by the toolholder manufacturer to avoid insert rocking or premature breakage. Inspect the toolholder pocket for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT3LCK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\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: 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: 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\u003eChipbreaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\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\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0969 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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1764 pounds\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: 1770917\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750526550322,"sku":"1770917","price":236.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e2f33078bbea1fa151095ca54b31442.jpg?v=1788916197","url":"https:\/\/voomisupply.com\/products\/kennametal-1770917-threading-insert-nt3lck-kc5010-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
