Built from HSS-E cobalt high-speed steel and finished with a GLT-1 coating, this tap handles demanding thread-cutting applications where tool life and surface finish matter. The spiral point geometry pushes chips ahead of the tap and out through the hole, keeping the flutes clear during the cut. With a plug chamfer, H3 thread limit, and 2B class of fit, it produces threads that meet standard inch-series tolerance requirements. Licensed machinists, tool-and-die makers, and maintenance technicians use this tap in production and repair work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading in steel, stainless steel, cast iron, and non-ferrous metals. The 1-64 UNC thread size places it in miniature fastener territory, common in precision instrument assembly, electronics enclosures, and small mechanical subassemblies. The right-hand cut and 2-flute design are standard for this thread size range, balancing chip clearance with tool strength at small diameters. It is not designed for blind-hole applications where chip evacuation forward is not possible.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, keeping flutes clear in through-hole applications\u003c\/li\u003e\n\u003cli\u003eHSS-E cobalt construction provides elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eGLT-1 coating reduces friction and improves tool life in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) for general-purpose through-hole starting and cutting\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit for standard inch-series thread tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, no coolant-through  -  compatible with standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading operations producing 1-64 UNC, 2B class of fit threads.

Ensure the machine spindle and tap holder are properly aligned before engagement  -  misalignment at small diameters causes tap breakage. Use appropriate cutting fluid or tapping compound for the workpiece material. Because this is a spiral point tap, it requires a through-hole; do not use in blind holes where chips cannot exit forward.\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: 2B\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\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: Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: GLT-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.7717 inches (45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.2760 inches (7.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches (3.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.4724 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 2.79 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BU20C300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 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: EMUGE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BU20C300.5000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":52125328638258,"sku":"BU20C300.5000","price":98.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e5d0dea87e2c189cddfef11f03d2c4d_5aaa8cbd-197b-4480-845a-3873afd7831c.jpg?v=1790087520","url":"https:\/\/voomisupply.com\/products\/emuge-bu20c300-5000-spiral-point-tap-1-64-unc-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
