Built to 3\/8-16 UNC specifications with a 3B class of fit and an X thread limit, it delivers consistent, accurate threads in production and repair environments. The tap is manufactured from HSS-E (high-speed steel with cobalt) for elevated heat and wear resistance, and carries a GLT-1 coating to further extend tool life. With 3 flutes and a plug chamfer, it pushes chips forward through the hole during cutting. Licensed machinists and toolroom technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in steel and cast iron workpieces, both in residential shop and commercial production settings. The left-hand thread direction makes it appropriate for applications requiring reverse-thread fasteners or left-hand threaded assemblies. It is part of the EMUGE Rekord B series, a line recognized in precision threading applications across manufacturing and maintenance operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand thread direction for reverse-thread applications\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt construction for improved heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eGLT-1 coating extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, suited for through-hole operations\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (4 to 5 threads) for standard through-hole entry\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with X thread limit for controlled tolerance threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of 3\/8-16 UNC left-hand threads in steel and cast iron workpieces.

Ensure the workpiece is securely fixtured and the pilot hole diameter matches the recommended tap drill size for 3\/8-16 UNC before beginning. Coolant-through is not supported on this tap; apply cutting fluid externally as appropriate for the workpiece material. Verify spindle or wrench rotation direction is set to left-hand before engaging the tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug (4 to 5 threads)\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: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: GLT-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 22.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 17.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 7.26 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\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: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Rekord B (BU20K560)\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: EMUGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BU20K560.5011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":67584780239154,"sku":"BU20K560.5011","price":112.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dc6a35cdb29712c3563e57646a5c950_442794f6-cb64-4cc0-bf4c-a4248e609967.jpg?v=1790416015","url":"https:\/\/voomisupply.com\/products\/emuge-bu20k560-5011-spiral-point-tap-3-8-16-unc-lh-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
