Built from high-speed steel with a bright, uncoated finish, this tap is engineered for threading operations that require cutting close to the bottom of a blind hole. It features 4 flutes and meets a 2B class of fit with an H5 thread limit, making it suitable for standard tolerance threading work in ferrous and non-ferrous materials. Overall length is 3.375 inches, with a thread length of 1.656 inches. Machinists and tool-and-die professionals reach for bottoming taps as the final step in a three-tap sequence or whenever full thread depth near the hole bottom is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, and production environments where 1\/2-13 UNC threads are common. It is appropriate for threading operations in steel, aluminum, cast iron, and similar workpiece materials when used with proper cutting fluid. The bottoming chamfer design allows the tap to engage threads within 1 to 2 pitches of the hole bottom, making it the correct choice for shallow blind holes where a taper or plug tap cannot complete the thread depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with right-hand direction\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance and rigidity\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit and 2B class of fit for standard tolerance applications\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 oil or coolant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard bottoming tap for 1\/2-13 UNC threaded holes in general machining and repair applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed using a tap wrench, tapping head, or machine spindle rated for the appropriate torque range for the workpiece material. Always use a suitable cutting fluid to extend tool life and improve thread finish. Ensure the tap is aligned perpendicular to the workpiece surface before engagement to avoid thread distortion or tap breakage. In a blind-hole sequence, use a taper tap followed by a plug tap before finishing with this bottoming tap.\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\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\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: MSC-04484143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690724426034,"sku":"MSC-04484143","price":25.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c1a877c13a72de9319759ea6a3cf181.jpg?v=1788274488","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04484143-straight-flute-tap-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
