Built from high-speed steel with a bright, uncoated finish, it features 3 flutes and a taper chamfer that guides the tap into the workpiece gradually, reducing the torque required to start the cut. The H2 thread limit provides a controlled fit for 2B and 3B class-of-fit applications. Overall length is 1-15\/16 inches with a thread length of 5\/8 inches. Straight flute geometry makes this tap well suited for through-hole and short blind-hole applications where chip evacuation is manageable with standard technique.\u003c\/p\u003e\u003cp\u003eThis tap is intended for tapping applications in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It is a standard production tap used in machine shops, maintenance environments, and field repair work wherever 5-40 UNC threads are required. The taper chamfer style makes it appropriate for through-holes or for starting threads in blind holes before following with a plug or bottoming tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-40 UNC thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eTaper chamfer for guided entry and reduced starting torque\u003c\/li\u003e\n\u003cli\u003e3 straight flutes sized for general-purpose chip handling\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for 2B and 3B class-of-fit tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for wear resistance across multiple materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for 5-40 UNC thread cutting in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Always ensure the hole is drilled to the correct tap drill size for 5-40 UNC before tapping. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tool life. For blind-hole applications, take care not to bottom the tap against the hole floor, which can cause tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B and 3B\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\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches (1.937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/8 inches (0.374 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\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.7449 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: 102\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: 1013000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740372468018,"sku":"1013000","price":21.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0cb814f9cb91c99306656e528e111ee.jpg?v=1788824587","url":"https:\/\/voomisupply.com\/products\/osg-1013000-straight-flute-tap-5-40-unc-taper-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
