It is manufactured from High-Speed Steel-E (HSS-E) and carries a GLT-1 coating for extended tool life in demanding applications. The tap features a 3-flute, plug chamfer geometry with a right-hand thread direction and is ground to a 3B class of fit at H4 thread limit. With an overall length of 4.331 inches and a thread length of 25 millimeters, this tap suits production and job-shop environments where accurate, repeatable internal threads are required. Machinists and tool-room professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations across a range of workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals. The spiral point design pushes chips forward ahead of the tap, making it most effective in through-hole applications where chip evacuation along the flutes is not required. It is appropriate for use in CNC machining centers, drill presses, and manual tapping operations where consistent 1\/2-13 UNC thread quality is the objective.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form ground to 3B class of fit at H4 thread limit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003eHSS-E construction provides improved toughness and heat resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eGLT-1 coating reduces friction and wear, extending tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows easy starting and smooth thread engagement\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping equipment and toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel, stainless steel, cast iron, and non-ferrous metals.

Ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before engagement to avoid tap breakage or thread distortion. Apply appropriate cutting fluid for the workpiece material, particularly when tapping stainless steel or hardened steels. Coolant-through is not supported on this 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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 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: H4\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\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: High-Speed Steel-E (HSS-E)\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: 4.331 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.984 inches (25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches (9.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 6.99 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0769 inches\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: CU20C310\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: CU20C310.5013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":51997914431794,"sku":"CU20C310.5013","price":130.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/856b8009d330d2dfb4f82c2e88cddd78.jpg?v=1789994483","url":"https:\/\/voomisupply.com\/products\/emuge-cu20c310-5013-spiral-point-tap-1-2-13-unc-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
