Manufactured to the LT16NL insert style and coated with TiAlN via a PVD process, this insert carries the KC5025 grade designation, which is engineered for tough threading applications requiring wear resistance and edge stability. The insert covers a pitch range of 0.50 to 3.00 mm (48 to 8 TPI) and conforms to a partial profile 60-degree thread standard. With a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 0.1430 inch (3.44 mm), it seats securely in compatible LT16NL toolholders used in CNC turning and threading operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading on CNC lathes in metalworking environments, including both job shop and production floor settings. The left-hand orientation makes it appropriate for reverse-thread applications or left-hand spindle configurations. Machinists and tooling specialists working on threaded bores in ferrous and non-ferrous materials will find this insert applicable across a broad pitch range, eliminating the need to swap inserts for fine and coarse threads within the 48-8 TPI span. The partial profile geometry allows it to cut most standard 60-degree thread forms without requiring a dedicated insert per pitch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with TiAlN PVD coating for wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread standard covers 48-8 TPI (0.50-3.00 mm pitch) in a single insert\u003c\/li\u003e\n\u003cli\u003eLeft-hand internal threading orientation for reverse-thread bores and left-hand spindle setups\u003c\/li\u003e\n\u003cli\u003eLT16NL insert style with 3\/8 inch inscribed circle for positive seating in matching toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0020 inch (0.05 mm) for precise thread root definition\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1551 inch (3.94 mm) for secure clamping in the toolholder pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style threading insert for toolholders accepting the LT16NL insert style with a 3\/8 inch inscribed circle.

Power down and lock out the machine before handling or replacing inserts. Use the appropriate torx or clamping screw torque recommended by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can fracture under uneven clamping force. Inspect the toolholder pocket for chips or debris before seating the insert to ensure full contact and accurate positioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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 Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\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\u003eThreads Per Inch\u003c\/strong\u003e: 48-8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50-3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inch (3.44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0020 inch (0.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inch (3.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0882 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: 1743831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732799455538,"sku":"1743831","price":533.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df30a1bc1a3cd775b811e7e646493c14.jpg?v=1788746944","url":"https:\/\/voomisupply.com\/products\/kennametal-1743831-threading-insert-60-deg-48-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
