Built from high-speed steel with a bright uncoated finish, this tap handles 1\/2-28 UNEF right-hand threads and is suited for general-purpose tapping in a machine shop or field maintenance environment. With 4 flutes and an H3 thread limit, it produces consistent thread geometry in a range of workpiece materials. Overall length is 3.375 inches and the tool weighs 0.25 pounds.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in metalworking and machining applications requiring fine unified thread form at 1\/2-28 UNEF. The bottoming chamfer style makes it the correct choice when threads must extend to the bottom of a blind hole. It is typically deployed in manual tapping handles, drill presses, CNC lathes, or tapping machines in production and maintenance settings. Machinists, toolmakers, and mechanical maintenance technicians use this tap when precise thread depth control is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-28 UNEF thread size and standard for fine-pitch threading applications\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes provide chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent tolerance for standard fit classes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no added coating to alter cutting geometry or dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or shop-stock straight flute tap for 1\/2-28 UNEF bottoming applications in manual and machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or trained mechanical technician should select the correct tap drill size for 1\/2-28 UNEF threads before use. Always use appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread finish. Secure the workpiece firmly before tapping, and back the tap off periodically to break chips when working in blind holes. Inspect the tap for wear or chipping before each use and replace if damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF\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: Bottoming\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\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\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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\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: JY4844262\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707343995186,"sku":"JY4844262","price":36.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cc44e53a41b7251b12e36042c736c05.jpg?v=1788439765","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4844262-straight-flute-tap-1-2-28-unef","provider":"Voomi Supply","version":"1.0","type":"link"}
