Manufactured in the NA6L2 style with a KCU25 grade carbide substrate, this insert carries an AlTiN finish applied via PVD coating process. The 29-degree included angle and a cutting tip width of 0.1802 inches are matched to the Acme thread standard at 2 threads per inch (TPI). Left-hand orientation makes it suitable for left-hand threaded workpieces. It belongs to Kennametal's Top Notch series and is sold individually with a minimum order quantity of 5 units. Machinists and toolroom technicians use this insert in CNC lathes and manual threading operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for Acme thread forms, which appear frequently in lead screws, power screws, vises, and linear actuation hardware across industrial and manufacturing environments. The left-hand configuration is critical for applications where thread direction is specified as left-hand. The Top Notch series is suited for medium to heavy threading passes where a secure insert-to-holder connection is required. Shops performing both internal and external threading on a single setup will find the dual-rated thread type designation useful for reducing changeovers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with PVD-applied AlTiN finish for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e29-degree included angle matched to the Acme thread standard\u003c\/li\u003e\n\u003cli\u003e2 TPI internal pitch for coarse Acme thread profiles\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for left-hand threaded components\u003c\/li\u003e\n\u003cli\u003eRated for both internal and external threading operations\u003c\/li\u003e\n\u003cli\u003eTop Notch series seating geometry for positive insert location\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept NA style, size 6 inserts.

Ensure the machine spindle is fully stopped and the tool turret is locked before seating or removing the insert. Verify left-hand orientation and thread direction on the workpiece setup before initiating a threading pass. Do not exceed the recommended depth of cut or feed rate for the KCU25 grade in the material being threaded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NA6L2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\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: AlTiN\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: 2 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: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.1802 inches (4.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 inches (0.13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3831 inches (9.73 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.2020 inches\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 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: 4033833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735296246066,"sku":"4033833","price":452.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5979e4b35b50e1b1f29b6d42a3a8fe66.jpg?v=1788771564","url":"https:\/\/voomisupply.com\/products\/kennametal-4033833-threading-insert-acme-2-tpi-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
