Configured as a plug chamfer tap, it starts threading several threads in before full cutting engagement, making it well suited for through-holes and moderately deep blind holes. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance across general-purpose threading applications. It cuts a 1\/4-28 UNF right-hand thread to a 3B class of fit with an H3 thread limit, providing the dimensional accuracy required for standard fastener assemblies in machining and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, and production environments where 1\/4-28 UNF threads are required. The plug chamfer style makes it a versatile choice for both through-hole and blind-hole work when sufficient clearance exists at the bottom of the hole. It is appropriate for use in manual tapping, drill press setups, and CNC tapping cycles where coolant-through tooling is not required. Machinists, toolmakers, and skilled tradespeople working in metalworking, HVAC equipment fabrication, and mechanical assembly will find it a direct fit for standard inch-series fine-thread work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF right-hand thread form cuts standard fine-pitch inch-series threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 flutes provides smooth chip clearance and stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003e3B class of fit and H3 thread limit deliver consistent dimensional accuracy for standard fastener assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands heat generated during tapping in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suits general-purpose use without added coating costs\u003c\/li\u003e\n  \u003cli\u003e1 inch thread length and 2-1\/2 inch overall length fit standard tap holders and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight flute plug tap for use in any application requiring a 1\/4-28 UNF 3B class of fit internal thread.

Always drill the correct tap drill size for a 1\/4-28 UNF thread before tapping, and secure the workpiece firmly to prevent movement during the operation. Apply a suitable cutting fluid or tapping compound to extend tool life and improve thread quality. Back the tap off periodically to break and clear chips, particularly in deeper holes, to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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: Plug\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: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\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: 0.06 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-04470282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698503942450,"sku":"MSC-04470282","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fc5a802760536b97bab4d28ff7f33a7.jpg?v=1788363901","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04470282-straight-flute-tap-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
