It features a 2-flute, plug chamfer geometry that pushes chips ahead of the cutting edge, keeping the flutes clear during production tapping. Built from high-speed steel with a bright finish, this tap handles a wide range of workpiece materials including aluminum, cast iron, and both low- and high-carbon steel. The H2 thread limit designation indicates a tight tolerance grind suitable for 2B and 3B class-of-fit threads. Overall length is 1.938 inches with a thread length of 0.625 inches and a shank diameter of 0.141 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for light to medium production work in job shops, maintenance environments, and precision manufacturing where 5-40 UNC fastener holes are required. The plug chamfer makes it the standard choice for through-hole tapping in materials ranging from cast aluminum to medium-carbon steel. It belongs to OSG Series 105 and is sold individually, making it practical for both toolroom stocking and single-job procurement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, preventing re-cutting in through-hole applications\u003c\/li\u003e\n\u003cli\u003eH2 thread limit grind produces consistent 2B and 3B class-of-fit threads\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles aluminum, cast iron, low-, medium-, and high-carbon steel\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides smooth thread lead-in for through-hole work\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating keeps cost low for general-purpose use\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 5-40 UNC threads in through-hole applications across aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces per the material application data provided.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a machine tap holder or used with a tapping head that provides proper axial float to prevent thread distortion. Ensure the spindle is fully stopped and power is locked out before changing taps in any machine tool. Use a compatible tapping fluid or cutting oil for the workpiece material to extend tap life and maintain thread quality. Follow shop practices and applicable OSHA machine guarding standards during setup and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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 \/ 3B\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: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 1.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 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: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 1207000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740374958386,"sku":"1207000","price":26.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7862ae23b82825b96089481276366de2.jpg?v=1788824608","url":"https:\/\/voomisupply.com\/products\/osg-1207000-spiral-point-tap-5-40-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
