Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap handles aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The plug chamfer provides a gradual lead-in, making it suited for through-hole threading applications. With 3 flutes and a right-hand thread direction, it produces 5\/8-18 UNF threads to a 3B class of fit at an H3 thread limit. Overall length is 3.813 inches with a thread length of 1.91 inches. Licensed machinists and tool-and-die professionals are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis spiral point tap is used in production and maintenance machining environments where through-hole tapping is required. The 5\/8-18 UNF thread form is common in precision mechanical assemblies, hydraulic fittings, and structural fastener applications found in both industrial and commercial settings. The TiN coating extends tool life and reduces friction during cutting, making this tap a reliable choice for high-volume tapping operations or repetitive maintenance work. It is part of OSG Series 105 and is sized for use in standard tap holders and CNC tapping heads that accept a 0.48-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-18 UNF thread form with 3B class of fit and H3 thread limit for precise tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction, extends tool life, and improves chip flow\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3 flutes optimized for through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement, non-interrupted thread design\u003c\/li\u003e\n\u003cli\u003eCompact 0.48-inch shank diameter compatible with standard tap holders and CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap holders, tapping heads, and CNC machining centers that accept a 0.48-inch shank diameter and are configured for 5\/8-18 UNF right-hand thread cutting in through-hole applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by qualified machinists in manual or CNC tapping operations. Always secure the workpiece firmly and ensure the tap holder is properly aligned before beginning the threading cycle. Power down or disengage the spindle before changing tooling. Follow standard speeds and feeds for the workpiece material and coating type; refer to OSG Series 105 application guidelines and applicable ANSI standards for thread tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\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: 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: 3\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.91 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel, Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1233405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737356009778,"sku":"1233405","price":105.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58652bc6ac49e1cbe71d5c5ebce6dcb7.jpg?v=1788787505","url":"https:\/\/voomisupply.com\/products\/osg-1233405-spiral-point-tap-5-8-18-unf-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
