Built from 3% vanadium high-speed steel with an oxide coating, it delivers reliable wear resistance in production and maintenance threading applications. The modified bottoming chamfer allows threading closer to the bottom of blind holes than a standard taper tap. With 3 right-hand spiral flutes and a 40-degree helix angle, this tap efficiently evacuates chips upward out of the hole during cutting. Overall length is 1.9400 inches with a thread length of 6 mm. Licensed machinists, toolroom technicians, and precision fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading small-diameter blind holes in light metals, plastics, and mild steels where chip evacuation is critical to thread quality. The spiral flute design is especially effective in CNC tapping centers and manual drill press operations where consistent chip flow reduces tap breakage risk. The 5-40 thread specification is common in instrument hardware, electronics enclosures, and small mechanical assemblies. The oxide finish provides a mild level of lubricity and corrosion resistance during use and storage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 thread size with 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003e3% vanadium high-speed steel construction for increased wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix angle promotes upward chip evacuation in blind hole applications\u003c\/li\u003e\n  \u003cli\u003eOxide coating adds surface lubricity and protects against corrosion during storage\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.9400 inches suits restricted-access applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use threading tool for machines and tap holders accepting a 3.58 mm shank diameter, suitable for 5-40 right-hand thread applications in CNC tapping centers, drill presses, and manual tapping fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways ensure the workpiece is securely fixtured and the spindle or tap handle is properly aligned before beginning the threading operation. Use an appropriate cutting fluid or tapping oil for the workpiece material to extend tap life and improve thread finish. Inspect the tap for chipping or wear before each use, as a damaged tap can seize in the hole and cause workpiece damage. Follow machine tool manufacturer guidelines for spindle speed and feed rate when using in powered tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral (Fast Helix)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (3% Vanadium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.58 mm\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\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T1604202B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728563634482,"sku":"T1604202B","price":31.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ff62c98e3194455ed61d33136cc81b5.jpg?v=1788693391","url":"https:\/\/voomisupply.com\/products\/accupro-t1604202b-spiral-flute-tap-5-40-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
