Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread cutting performance in production and maintenance environments. The taper chamfer eases entry into the workpiece, making it well suited for through-hole threading applications. With 4 flutes and an H3 thread limit, it holds consistent tolerance for 3B class of fit threads. Overall length is 3.375 inches, with a thread length of 1.656 inches. Licensed machinists, toolmakers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is used wherever 1\/2-13 UNC internal threads are required, including general machining, fabrication shops, and field maintenance work. The taper chamfer style is most effective in through-hole applications, where the gradual lead allows the tap to start straight and cut progressively. It is appropriate for use in manual tapping with a tap wrench or in light-duty machine tapping setups. Right-hand thread direction follows standard UNC convention.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eTaper chamfer for easy starting in through-hole applications\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in shorter-chip materials\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for 3B class of fit tolerance\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for applications requiring 1\/2-13 UNC, 3B class of fit internal threads in through-hole configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTaps should be installed and operated by qualified machinists or maintenance technicians familiar with threading procedures. Secure the workpiece firmly before tapping, and use an appropriate cutting fluid to reduce heat and extend tool life. Never force a tap — back off periodically to break chips and clear the flutes. If using in a machine tapping setup, verify spindle speed and feed rate are appropriate for the workpiece material before proceeding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.656 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 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: 0.12 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-04474151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694788510002,"sku":"MSC-04474151","price":20.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/944ac3b4b948773f5506a59c0320befe.jpg?v=1788328417","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04474151-straight-flute-tap-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
