Built from high-speed steel (HSS) with a TiCN coating, it delivers extended tool life and reduced friction in production and maintenance threading operations. The plug chamfer style makes it well suited for through-hole applications where the tap can advance freely into the cut. With an overall length of 3-13\/16 inches and a thread length of 1-13\/16 inches, it fits standard tap holders and machine spindles used by machinists and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in machine shops, industrial maintenance environments, and precision manufacturing applications. It cuts right-hand 5\/8-18 UNF threads to a 3B class of fit with an H3 thread limit, making it appropriate for applications requiring close tolerance internal threads. Material applications include aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. It operates without coolant-through capability, so it is best suited for tapping machines or CNC equipment using flood or drip coolant externally.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF right-hand thread form, 3B class of fit with H3 thread limit for controlled tolerance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance across steel and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (4-5 thread lead) optimized for through-hole threading applications\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes promote chip clearance in shorter-chipping materials\u003c\/li\u003e\n  \u003cli\u003eShank diameter of 0.48 inches with a 0.36-inch square drive for positive torque engagement in standard tap holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OSG Series 101 straight flute tap for use in standard tap holders and CNC tapping heads accepting a 0.48-inch shank diameter with a 0.36-inch square drive.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle to avoid tap breakage or thread damage. This tap does not feature coolant-through capability, so adequate external lubrication or flood coolant should be applied during the operation. Always verify that the tap holder and drive square are properly sized and torqued for the shank before running.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 18\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\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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: 1124008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742885216562,"sku":"1124008","price":94.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fd8b55a6c399c09ca43eaad524cdaa3.jpg?v=1788840225","url":"https:\/\/voomisupply.com\/products\/osg-1124008-straight-flute-tap-5-8-18-unf-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
