It handles external pitch ranges of 0.70 to 3.00 mm and 8 to 36 TPI, and internal pitch ranges of 1.25 to 3.50 mm and 7 to 20 TPI. The KCU25 grade provides a balance of toughness and wear resistance suited to interrupted cuts and variable-feed threading passes. Machinists and CNC programmers in production and job-shop environments rely on inserts like this for repeatable thread form accuracy across a wide pitch range.\u003c\/p\u003e\n\u003cp\u003eThis threading insert is used in metalworking applications where precise thread profiles are required on external or internal features of turned components. Typical installations include general-purpose threading on ferrous and non-ferrous workpieces in both production and maintenance machining environments. The wide pitch coverage makes it adaptable to both coarse and fine thread standards, reducing the number of insert grades a shop needs to stock for threading operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal pitch range of 0.70 to 3.00 mm covers 8 to 36 TPI for broad threading versatility\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range of 1.25 to 3.50 mm covers 7 to 20 TPI\u003c\/li\u003e\n  \u003cli\u003eNT2L insert style for standard threading toolholders\u003c\/li\u003e\n  \u003cli\u003eKCU25 carbide grade balances toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle insert per package; minimum order quantity of 5 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with NT2L-style threading toolholders and boring bars accepting the NT2L insert seat.

Power down and lock out the machine spindle before any insert change. Seat the insert fully and evenly against the pocket locating surfaces before torquing the clamping screw to the toolholder specification. Inspect the insert edge and thread form after the first threading pass to confirm profile accuracy before running production quantities.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT2L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Pitch Range (Metric)\u003c\/strong\u003e: 0.70 to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Pitch Range (Imperial)\u003c\/strong\u003e: 8 to 36 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range (Metric)\u003c\/strong\u003e: 1.25 to 3.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range (Imperial)\u003c\/strong\u003e: 7 to 20 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4109938\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737732120882,"sku":"4109938","price":211.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09fe4b54f3e7551248a49783d73990eb.jpg?v=1788792936","url":"https:\/\/voomisupply.com\/products\/kennametal-4109938-threading-insert-nt2l-kcu25","provider":"Voomi Supply","version":"1.0","type":"link"}
