It features four flutes ground from high-speed steel with a bright, uncoated finish and a taper chamfer that eases thread entry and reduces starting torque. The H3 thread limit holds tolerances appropriate for a 3B class of fit, making it a standard choice for general-purpose threading in production and maintenance environments. Overall length is 2.5 inches with a 1-inch thread length. Machinists, tool-and-die makers, and maintenance technicians use this tap for hand tapping and machine tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading through-holes and blind holes in steel, aluminum, cast iron, and similar machinable materials where a 1\/4-20 UNC thread form is required. The taper chamfer — typically 8 to 10 threads of lead — makes it the preferred starting tap when beginning a thread in a new hole. It fits standard tap wrenches and machine tap holders designed for the 1\/4-20 shank size, and is appropriate for low-volume production runs, repair work, and field maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for guided thread starting in new holes\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent 3B class-of-fit tolerances\u003c\/li\u003e\n  \u003cli\u003eFour flutes for balanced cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common machinable materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no additional coating buildup on thread flanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC straight flute tap compatible with tap wrenches, T-handle tap wrenches, and machine tap holders sized for 1\/4-20 tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways drill the correct tap drill size before threading; an undersized hole increases torque and risk of tap breakage. Secure the workpiece firmly and align the tap perpendicular to the drilled hole before applying cutting pressure. Use appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. For hand tapping, advance the tap forward then back a quarter turn periodically to break chips and clear the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 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: H3\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04470225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722343186738,"sku":"MSC-04470225","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffba95223b5a473687102922b8aea45e.jpg?v=1788589704","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04470225-straight-flute-tap-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
