Built from High-Speed Steel-E (HSS-E) with a GLT-1 coating, it delivers extended tool life and reduced friction in demanding production environments. The 1\/2-13 UNC thread form is cut with a plug chamfer and a right-hand thread direction, producing a 2B class of fit with an H6 thread limit. At 4.331 inches overall length with a 0.984-inch thread length, this tap is suited for CNC machining centers and manual tapping operations where consistent thread quality is required. Machinists and production tooling specialists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is used for through-hole threading applications in manufacturing and job shop environments. The spiral point geometry pushes chips ahead of the tap and out through the bottom of the hole, making it the standard choice for production through-hole work in steel, stainless steel, cast iron, and non-ferrous metal workpieces. It is not designed for blind-hole applications. The 1\/2-13 UNC designation covers one of the most common fastener thread sizes in inch-standard mechanical assemblies, making this tap a frequent production item across general machining, structural, and equipment repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry drives chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHSS-E construction provides toughness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eGLT-1 coating reduces friction and extends service life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 flutes balances cutting load entry and thread engagement\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit and 2B class of fit for standard inch-series fastener thread quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement, compatible with standard tapping chucks\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 metal workpieces.

Ensure the workpiece is securely fixtured and the through-hole is drilled to the correct tap drill diameter for 1\/2-13 UNC before threading. Power down and de-energize the machine before changing or setting the tap in the holder. Use appropriate cutting fluid for the workpiece material to preserve coating life and thread quality.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: H6\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 Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\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 (25.00 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 (13 threads per inch)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.112 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CU20C300\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: CU20C300.5013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMUGE","offers":[{"title":"Default Title","offer_id":52057880330546,"sku":"CU20C300.5013","price":130.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/856b8009d330d2dfb4f82c2e88cddd78_1e1e34ea-2c77-4454-947f-4bef8efd3c21.jpg?v=1790039253","url":"https:\/\/voomisupply.com\/products\/emuge-cu20c300-5013-spiral-point-tap-1-2-13-unc-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
