It produces a 5\/8-18 UNF right-hand thread using a modified bottoming chamfer with 2 to 2.5 chamfered threads, making it well suited for work close to the bottom of a hole. The tap is manufactured from cobalt high-speed steel and finished with a TiCN coating for increased surface hardness and wear resistance. Overall length is 3.813 inches with a shank diameter of 0.48 inches and an H7 thread limit. Machinists, toolmakers, and maintenance technicians install this tap in CNC machining centers, drill presses, and tapping arms.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading applications across a range of ferrous and non-ferrous workpiece materials, including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The thread forming method is preferred in these materials because it work-hardens the thread form, producing stronger threads with no chip generation. Material application codes P and N confirm suitability across steel and non-ferrous metal families. The modified bottoming chamfer allows threading to within a short distance of the hole bottom, a common requirement in precision machined components and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF right-hand thread form for unified fine-pitch applications\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for near-bottom reach in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life in abrasive and harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit for consistent fit class in production tapping\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature — compatible with flood or external coolant delivery\u003c\/li\u003e\n  \u003cli\u003eChipless thread forming process eliminates chip-related tap breakage in blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces.

Cutting fluid or tapping compound appropriate for the workpiece material should be applied; do not run a thread forming tap dry in steel. This tap does not generate chips but requires adequate lubrication to prevent galling. Installation is performed by machinists and toolroom technicians; always confirm machine spindle speed and feed rate are set to values appropriate for the workpiece material and hole depth before engaging the tap.\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\u003eThreads per Inch\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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: 1.0906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.126 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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 14001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 1400152008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728429908274,"sku":"1400152008","price":112.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_8d31bd55-0d3b-4b96-a8af-45a21aec28ae.jpg?v=1788691038","url":"https:\/\/voomisupply.com\/products\/osg-1400152008-thread-forming-tap-5-8-18-unf-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
