It carries the NTB2RA insert style with a K68 manufacturer grade and an equivalent C3 material grade, making it well suited for threading operations in harder ferrous and exotic materials. The uncoated bright finish allows close inspection of the cutting edge and is appropriate for applications where coating adhesion could interfere with thread form accuracy. The included angle measures 45 degrees, with a corner radius of 0.0031 inches and a tip-to-top height of 0.1260 inches. This insert is installed and serviced by machinists and CNC turning specialists working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert handles a pitch range of 16 to 20 TPI on the American Buttress thread standard, making it applicable to power transmission components, jack screws, and heavy-load linear motion hardware where the asymmetric Buttress profile is specified. It is a right-hand insert intended for standard right-hand thread cutting passes. The Top Notch series provides a repeatable, positive-lock seating system that maintains consistent insert positioning across tool changes, which is critical for holding thread form tolerances in repeat production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAmerican Buttress thread form with a 45-degree included angle for asymmetric load-bearing thread profiles\u003c\/li\u003e\n\u003cli\u003ePitch range of 16-20 TPI covers common Buttress thread applications in power transmission and structural assemblies\u003c\/li\u003e\n\u003cli\u003eK68 carbide grade with uncoated bright finish for sharp cutting edges and straightforward edge inspection\u003c\/li\u003e\n\u003cli\u003eHandles both internal and external threading operations with the same insert geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard thread direction passes\u003c\/li\u003e\n\u003cli\u003eTop Notch series seating system maintains repeatable insert positioning across tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series threading toolholders that accept NTB-style inserts in size 2.

Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert, as contamination in the pocket will affect thread form accuracy. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTB2RA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 16-20 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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1260 inches (3.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0031 inches (0.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.15 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0079 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: 1182375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734892249394,"sku":"1182375","price":204.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7d182a03672c7b7737ba1c44657ab89.jpg?v=1788767696","url":"https:\/\/voomisupply.com\/products\/kennametal-1182375-threading-insert-k68-carbide-16-20-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
