It produces a 5\/8-11 UNC right-hand thread to a 3B class of fit with an H3 thread limit, making it suitable for applications requiring consistent, tolerance-controlled threads. The plug chamfer — with 3 to 5 threads of lead — allows the tap to start in a through-hole or a deep blind hole with adequate clearance. At 3-13\/16 inches overall length and a 1-13\/16 inch thread length, this tap fits standard tap holders and machine spindles used by machinists and maintenance trades alike. The 4-flute straight design provides good chip control in the short, broken chips typical of cast iron and carbon steels.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in through-holes and blind holes where chips can be cleared manually or with cutting fluid. Material applications include aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The oxide coating provides a mild lubricity advantage and light corrosion resistance during storage and use. It is well-suited for manual tapping, drill press setups, and light CNC tapping operations in job shop, maintenance, and production environments. Individual packaging makes it a practical single-unit replacement for tool crib stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form with right-hand direction and 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for controlled tolerance in standard through-hole and blind-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3-5 thread lead for easy starting and versatile hole type usage\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes promote chip evacuation in short-chipping materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for durability and light lubricity\u003c\/li\u003e\n  \u003cli\u003eCompatible with aluminum, cast iron, and low- to high-carbon steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders, T-handle wrenches, and machine spindles accepting a 0.48-inch shank diameter.

Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. When tapping by hand, use a calibrated tap wrench and back off periodically to break chips. When used in a machine setup, verify spindle speed and feed rate are appropriate for the material and tap diameter to avoid tap breakage.\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\u003eThreads per Inch\u003c\/strong\u003e: 11\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-13\/16 inches (3.811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches (1.362 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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.19 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: 1123701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749640896818,"sku":"1123701","price":74.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d02dc59e31a4b5b8d45417122e54765b.jpg?v=1788908689","url":"https:\/\/voomisupply.com\/products\/osg-1123701-straight-flute-tap-5-8-11-unc-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
