Unlike cutting taps, this bottoming-style forming tap displaces material rather than cutting chips, producing strong, work-hardened threads with no swarf buildup in the hole. It carries an 8-32 UNC thread form at a 2B class of fit and features a TiCN coating over a high-speed steel body. The bottoming chamfer provides 1.5 to 2 thread lead, allowing threads to be formed close to the bottom of a blind hole. Qualified machinists, tool-and-die technicians, and HVAC or mechanical service professionals working with tapped assemblies use this tap in production and repair contexts.\u003c\/p\u003e\u003cp\u003eThe 2865208 is suited for blind hole threading applications in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The bottoming geometry makes it well-matched for applications where thread depth close to the floor of a blind hole is required and chip evacuation is a concern. The right-hand thread direction and standard 8-32 UNC form make it a direct fit for common fastener specifications found across HVAC equipment assemblies, electrical enclosures, and general mechanical fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting chips, reducing breakage risk in blind holes\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and lubricity for extended tool life in steel and aluminum\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1.5 to 2P lead allows threading close to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles the torsional loads of form tapping in low- and medium-carbon steels\u003c\/li\u003e\n\u003cli\u003eRight-hand, 8-32 UNC thread form at 2B class of fit matches common commercial fastener standards\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies use in standard tap handles and hand tapping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel.

Apply an appropriate tapping lubricant or cutting fluid matched to the workpiece material before starting. Clamp the workpiece securely and maintain axial alignment throughout the tapping operation to avoid tap breakage or thread distortion. Inspect the tap for wear or coating damage before each use, particularly when working in steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1.5 to 2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2865208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747161080114,"sku":"2865208","price":49.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec01f4bbd06e33892610ca18dc096847_84632376-b8af-43dc-a149-e9ab86ac8be4.jpg?v=1788876890","url":"https:\/\/voomisupply.com\/products\/osg-2865208-thread-forming-tap-8-32-unc-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
