Built from high-speed steel with a bright finish, this bottoming chamfer tap is suited for threading close to the bottom of a blind hole where maximum thread engagement is required. It carries an H2 thread limit and a 2B\/3B class of fit, making it appropriate for standard commercial and precision thread applications. With 2 flutes and right-hand threading, the spiral point geometry pushes chips ahead of the cut, keeping the flutes clear during the tapping operation. Overall length is 1.938 inches with a thread length of 0.323 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in manufacturing, machining, and maintenance environments where 5-40 UNC threads are required. Typical applications include tapping aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. It fits standard machine tapping setups and hand tapping operations where a bottoming chamfer is specified. The 0.141-inch shank diameter is compatible with standard tap holders for this size range. It is commonly used by machinists, toolmakers, and maintenance technicians across production and job-shop 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\u003eH2 thread limit with 2B\/3B class of fit for standard and precision thread tolerance\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction suitable for a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging during through-hole and shallow blind-hole tapping\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement, compatible with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, non-oversize, non-interrupted thread form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 5-40 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel.

Ensure the workpiece is securely fixtured and the correct pilot hole diameter for 5-40 UNC is drilled before tapping. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. When tapping blind holes with a bottoming chamfer tap, advance carefully to avoid bottoming out the tool against the hole floor under power.\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\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 \/ 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 \/ Finish\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: 0.323 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\u003eOversize\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: 1207100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743340658994,"sku":"1207100","price":33.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65398680501eed073eebed0f73ce970c_7b4fde69-8387-4b96-8d4a-4972fc938889.jpg?v=1788845868","url":"https:\/\/voomisupply.com\/products\/osg-1207100-spiral-point-tap-5-40-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
