Built from high-speed steel with a bright finish, this bottoming chamfer tap is suited for threading operations that require thread engagement close to the bottom of a blind hole. It carries an H2 thread limit and a 2B class of fit, making it appropriate for standard-tolerance fastener applications. With 2 flutes and right-hand thread direction, it is sized for small-diameter work where precision and controlled chip flow matter. Licensed machinists and toolroom technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The bottoming chamfer style makes it a second-operation tool, typically used after a taper or plug tap has started the thread, allowing threads to be cut as close to the bottom of a blind hole as the application requires. It is appropriate for both manual tapping and machine tapping setups in production or repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eH2 thread limit and 2B class of fit for standard-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eRight-hand, 3-48 UNC thread form for compatibility with standard inch-series fasteners\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement, suitable for general-purpose use\u003c\/li\u003e\n\u003cli\u003e2-flute design supports controlled chip evacuation in small-diameter tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to cut 3-48 UNC right-hand threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a qualified machinist or toolroom technician familiar with small-diameter tapping operations. Power down or disengage the spindle before loading or changing taps in any machine setup. Use a bottoming tap only after a taper or plug tap has already started the thread in blind-hole applications to reduce the risk of tap breakage. Ensure proper alignment and appropriate cutting fluid selection for the workpiece material before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1206100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742259380530,"sku":"1206100","price":42.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a8d9f0ded4c89d27b23d529f577cc3f.jpg?v=1788836267","url":"https:\/\/voomisupply.com\/products\/osg-1206100-spiral-point-tap-3-48-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
