Built from high-speed steel with a bright, uncoated finish, this plug chamfer tap is suited for through-hole and blind-hole threading operations where chip evacuation is manageable and thread depth is moderate. It features 4 flutes, a thread length of 2-9\/16 inches, and an overall length of 5-3\/4 inches. The H5 thread limit designation indicates a controlled oversize tolerance, making it appropriate for use with standard tapping lubricants and conventional machine or hand tapping setups.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in machine shops, maintenance facilities, and industrial fabrication environments. The 1-1\/4-8 UNS thread form is commonly found in heavy equipment, piping flanges, and structural fastening applications. The plug chamfer style makes it versatile for starting threads in both through holes and deeper blind holes with adequate clearance. It is installed by machinists and tool-and-die professionals using tapping machines, drill presses with tapping attachments, or hand tap wrenches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-8 UNS thread form for heavy-duty fastening and piping applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a range of materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style accommodates both through-hole and blind-hole threading\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for controlled tolerance fits\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip evacuation and cutting stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or tooling-up option for 1-1\/4-8 UNS straight flute plug tap applications in conventional machine and hand tapping operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a compatible tap holder or wrench sized for the tap shank. Always apply appropriate cutting fluid for the workpiece material before and during tapping. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole to avoid tap breakage or thread damage. Machinists should back off periodically to break chips and prevent binding, particularly in deeper holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-3\/4 inches\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\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: JY4870051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717430968626,"sku":"JY4870051","price":218.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40ddd1cc406673f6813fd78a404a279f.jpg?v=1788540330","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4870051-straight-flute-tap-1-1-4-8-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
