Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap provides a balance between starting ease and thread engagement depth. It carries a 3B class of fit and an H3 thread limit, making it suitable for standard tolerance through-hole and blind-hole tapping applications. With 4 flutes and a right-hand thread direction, it handles material removal efficiently in general-purpose production and maintenance environments. The overall length is 3-13\/16 inches and the thread length is 1-13\/16 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine-shop, maintenance, and production environments where 5\/8-11 UNC threads are required. The plug chamfer  -  typically 3 to 5 lead threads  -  allows the tap to start cleanly in a pre-drilled hole and is the most widely used chamfer style for both through-hole and moderately deep blind-hole work. Rated material applications include aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel, covering the majority of general machining scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for effective chip evacuation in short-chipping materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for versatile through-hole and blind-hole use\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright, uncoated finish\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  compatible with flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel.

Always drill the correct tap drill size for 5\/8-11 UNC before tapping and ensure the workpiece is securely fixtured. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Back the tap out periodically in manual operations to break chips and prevent binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\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: 11\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.192 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1123700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740402155826,"sku":"1123700","price":73.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fdb6348f80fb1ecbb55f6dca6148e09.jpg?v=1788824775","url":"https:\/\/voomisupply.com\/products\/osg-1123700-straight-flute-tap-5-8-11-unc-plug-3b-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
