It carries the KC5025 manufacturer grade with a TiAlN finish applied via PVD coating process, delivering wear resistance and thermal stability in demanding threading operations. The insert is left-hand orientation, covers a pitch range of 8 to 16 TPI, and features a 45-degree included angle. At 0.1642 inches tip to top and a corner radius of 0.0067 inches, this is a precision ground insert suited for CNC lathes and turning centers running ferrous and non-ferrous materials. Machinists and toolroom technicians install this insert into compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is appropriate for shops performing American Buttress thread forms, which are common in high-load applications such as hydraulic cylinder rods, power screws, and heavy mechanical assemblies. It handles both internal and external thread profiles in a single insert style, reducing tooling inventory. The left-hand configuration makes it the correct choice for left-hand spindle rotation setups or reverse-threaded components. Typical use environments include production machining cells and job shops running ISO material grades C2 and C6, which correspond to general-purpose and harder carbide classifications for turning and threading.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with TiAlN PVD coating for extended tool life in threading operations\u003c\/li\u003e\n\u003cli\u003eAmerican Buttress thread standard, internal and external compatible\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for reverse-thread or left-hand spindle applications\u003c\/li\u003e\n\u003cli\u003e8 to 16 TPI pitch range covers a broad set of Buttress thread specifications\u003c\/li\u003e\n\u003cli\u003e45-degree included angle per American Buttress thread form geometry\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert style for use with compatible KENNAMETAL Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series toolholders accepting NTB style, size 3 inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully and evenly in the pocket without over-torquing the clamping screw, as carbide is brittle and can fracture under uneven clamping load. Verify insert orientation and thread hand before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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: C2, C6\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: American Buttress\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: 8-16 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 45 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: 0.1642 inches (4.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0067 inches (0.17 mm)\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\u003eWeight\u003c\/strong\u003e: 0.031 pounds\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: 1799578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735358046514,"sku":"1799578","price":207.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d873b43aaccd432887583e522adfa5f.jpg?v=1788772074","url":"https:\/\/voomisupply.com\/products\/kennametal-1799578-threading-insert-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
