Built from vanadium high-speed steel with an oxide coating, this tap delivers durability and heat resistance in demanding machining environments. The modified bottoming chamfer allows threading closer to the bottom of blind holes, and the 45-degree helix angle promotes efficient chip evacuation up and out of the cut. With four flutes and a fast flute style, the 2233401 suits production tapping in alloy steel, carbon steel, cast iron, die steel, hardened steel, and stainless steel. It is typically installed by machinists and toolroom professionals using a tapping machine, CNC machining center, or hand tap wrench.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for precision threading applications requiring a 2B class of fit in UNF thread forms. The 5\/8-18 UNF thread size is common in automotive, aerospace, and general mechanical assemblies where fine-thread engagement is required. With an overall length of 3.937 inches (100 millimeters) and a shank diameter of 0.480 inches, the 2233401 fits standard tap holders for its size range. The modified bottoming geometry makes it particularly well-suited for blind-hole applications where a standard taper or plug tap cannot reach sufficient thread depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF thread form with right-hand thread direction and 2B class of fit\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading near the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle with fast flute style for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction with oxide coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompatible material applications include alloy steel, carbon steel, cast iron, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature; suitable for conventional external coolant or cutting oil application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders and CNC or manual tapping setups accommodating a 0.480-inch shank diameter; fits applications requiring a 5\/8-18 UNF 2B thread in ferrous workpiece materials including alloy steel, carbon steel, cast iron, die steel, hardened steel, and stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining professionals should secure the tap in a properly sized tap holder or collet and verify spindle alignment before beginning the threading operation. Apply an appropriate cutting fluid or tapping oil for the workpiece material to extend tool life and maintain thread quality. When tapping blind holes, set depth stops carefully to avoid tap breakage at the bottom of the hole. Inspect the tap for wear or chipping between uses, particularly when working with hardened steel or stainless steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium 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: 220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 2233401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752321843506,"sku":"2233401","price":183.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7e3959387b29dd53ebcc4f633dcbfc3_41e5860d-425d-469d-b181-1368773afb26.jpg?v=1788927441","url":"https:\/\/voomisupply.com\/products\/osg-2233401-spiral-flute-tap-5-8-18-unf-4-flute-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
