Built from cobalt high-speed steel with a bright\/uncoated finish, it cuts a 1-64 UNC right-hand thread to a 3B class of fit. The 35-degree helix angle drives chips up and out of the hole, which is the defining advantage of a spiral flute design in blind-hole applications. With an overall length of 1.772 inches and a thread length of 0.177 inches, this tap fits the Enorm series and is sized for precision small-diameter work. Licensed machinists and tool room technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind-hole threading operations on production and job-shop equipment. The modified bottoming chamfer allows threading close to the bottom of a blind hole while still providing enough lead-in for controlled engagement. At 1-64 UNC, this is a fine small-diameter thread commonly found in instrument enclosures, electronics hardware, and precision mechanical assemblies. The cobalt construction improves heat and wear resistance compared to standard M2 HSS, making it a practical choice for tougher steel alloys and harder non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree right-hand helix angle evacuates chips upward in blind-hole threading\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer enables threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides improved heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e3B class of fit for standard tolerance threaded fastener applications\u003c\/li\u003e\n\u003cli\u003e2-flute design suited to small-diameter tapping in 1-64 UNC applications\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish  -  compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind-hole threading in non-ferrous metals and steel.

Before tapping, confirm the pilot hole diameter matches the recommended drill size for a 1-64 UNC thread to avoid tap breakage. Apply a suitable cutting fluid for the workpiece material. Inspect the tap for chipping or wear regularly, as small-diameter cobalt taps are susceptible to breakage under side load or misalignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 64\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.177 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 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\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Enorm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.007 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EMUGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BU501010.5000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":51972009328946,"sku":"BU501010.5000","price":77.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26e69c8638dd8df65067fb175c36a18a.jpg?v=1789960815","url":"https:\/\/voomisupply.com\/products\/emuge-bu501010-5000-spiral-flute-tap-1-64-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
