Manufactured from high-speed steel with a bright uncoated finish, this tap features a 45-degree helix angle and a fast flute style that evacuates chips upward and out of the hole during the threading operation. It produces 1\/2-13 UNC threads to a 3B class of fit with an H3 thread limit, making it suitable for standard tolerance threaded assemblies. Overall length is 3-3\/8 inches. This tool is sized and configured for use by machinists, toolmakers, and maintenance technicians working in metal fabrication and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading blind holes in ferrous and non-ferrous metals where the bottoming chamfer allows threads to be cut to within a few pitches of the hole bottom. The 1\/2-13 UNC thread form is one of the most common fastener thread standards in North American manufacturing, making this tap a frequent choice for production threading, repair work, and custom fabrication. It is used in machine shops, maintenance departments, and toolrooms. The right-hand thread direction and right-hand flute direction are standard for conventional threading operations on manual or CNC tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle with fast flute style for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute direction for conventional tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC bottoming tap compatible with manual tap handles, tapping heads, and CNC tapping cycles that accept straight-shank taps of this size and overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using appropriate tapping equipment. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled pilot hole before beginning the threading operation. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread quality. Never force a tap if resistance increases unexpectedly, as this may indicate chip packing or tap binding and can result in 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\/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\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 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: 0.1 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-04619631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722296754482,"sku":"MSC-04619631","price":39.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f4316ccda949ed9b4bca3369066c8c8.jpg?v=1788588834","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04619631-spiral-flute-tap-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
