Built from high-speed steel (HSS) with a bright\/uncoated finish, this tap features a 45-degree helix angle that pulls chips up and out of the hole during the threading operation. The modified bottoming chamfer allows threading closer to the bottom of a hole than a standard taper or plug tap. At 2-23\/32 inches overall length, it fits standard tap holders and hand-tap wrenches. Machinists and toolroom technicians use this tap on manual mills, drill presses, and CNC machining centers for general-purpose threading work.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading ferrous and non-ferrous materials in production and job-shop environments where a 5\/16-18 UNC thread form is required. The 3-flute, fast-flute spiral design is particularly effective in ductile materials such as aluminum, mild steel, and soft alloys where long, stringy chips would otherwise pack and cause tap breakage. The right-hand thread direction and 3B class of fit make it appropriate for standard commercial and industrial fastener assemblies where moderate tolerance control is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form with right-hand thread direction and 3B class of fit for standard commercial tolerances\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle with fast-flute spiral geometry evacuates chips upward, reducing chip packing in ductile materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading closer to the bottom of a blind hole than plug or taper chamfer styles\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good toughness and wear resistance for general-purpose tapping applications\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup at the cutting edge, suitable for use with cutting fluid on a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit provides controlled oversize for use with standard tapping fluids and typical plated or finished fastener assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use threading tool compatible with standard tap holders, T-handle tap wrenches, and machine tap chucks configured for 5\/16-18 UNC spiral flute taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping operations should be performed by a qualified machinist following standard shop-safety procedures. Secure the workpiece firmly before beginning; never hand-hold a part during machine tapping. Apply an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Ensure the tap is properly aligned with the pre-drilled pilot hole to prevent tap breakage — misalignment is the leading cause of breakage with small-diameter taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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: 3B\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-23\/32 inches\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\/Uncoated\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: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04619318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714947547442,"sku":"MSC-04619318","price":20.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86981d5609cc347495ca7ab681347278.jpg?v=1788508224","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04619318-spiral-flute-tap-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
