Built from high-speed steel with a bright, uncoated finish, it delivers reliable performance in general-purpose tapping applications. The taper chamfer eases thread entry and reduces the torque required to start the cut. With 4 flutes and a thread limit of H4, this tap produces accurate 3B class of fit threads suitable for standard fastener assemblies. Overall length is 5.125 inches with a thread length of 2.5 inches. Licensed machinists, tool and die makers, and maintenance technicians are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis tap is intended for right-hand threading operations where a 1-12 UNF thread form is required. The taper chamfer style makes it well suited for through-hole applications where chip clearance along the flutes is sufficient. It is commonly used in manual tapping with a tap wrench or in low-speed machine tapping setups in job shop, maintenance, and production environments. No coolant-through capability is present, so external cutting fluid application is standard practice with this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-12 UNF thread form with 3B class of fit for standard-tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eTaper chamfer for easier thread entry and reduced starting torque\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute geometry for use in through-hole and open-end tapping\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for consistent tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with a variety of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for applications requiring a 1-12 UNF straight flute taper tap with a 3B class of fit and H4 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a proper tap wrench or machine tap holder sized for the shank diameter before use. Always secure the workpiece firmly and align the tap perpendicular to the hole to avoid tap breakage and thread misalignment. Apply a suitable cutting fluid throughout the tapping operation to reduce heat and extend tool life. Follow shop safety procedures and relevant machining standards when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 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\u003eWeight\u003c\/strong\u003e: 0.68 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04489126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697997087026,"sku":"MSC-04489126","price":70.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7a20e49b46f51f9debe504fe1e86594.jpg?v=1788356622","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489126-straight-flute-tap-1-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
