Built from High-Speed Steel-E-CO (cobalt-grade HSS) and finished with a TiCN coating, this tap delivers extended tool life and resistance to heat and wear. The modified bottoming chamfer — with 2 to 3 chamfered threads — allows threading close to the bottom of blind holes while still being suitable for through-hole applications. It carries a 2BX class of fit with H9\/H10 thread limits, making it appropriate for precision threading work in production environments. Licensed machinists and tooling specialists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in steel, stainless steel, cast iron, and non-ferrous metals, covering material application codes P, M, K, and N. It is well matched to both blind hole and through-hole threading operations. The 6 oil grooves support lubrication during the forming process, which is critical when displacing material rather than cutting it. A flute-to-diameter ratio of 3xD indicates it is built for moderate-depth threading applications in a variety of industrial and machining contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003eCobalt-grade HSS-E-CO material handles tough materials including stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2-3P) allows threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003e6 oil grooves support consistent lubrication during forming\u003c\/li\u003e\n  \u003cli\u003e2BX class of fit with H9\/H10 thread limits for precise thread geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 5\/8-18 UNF thread forming in steel, stainless steel, cast iron, and non-ferrous metals.

Ensure the tap is properly aligned with the drilled hole to avoid cross-threading or tap breakage. Power down all equipment and secure the workpiece before tool changes. Thread forming produces no chips but does work-harden the hole wall, so correct pilot hole diameter is essential — consult the applicable UNF forming tap drill chart before use.\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\u003eClass of Fit\u003c\/strong\u003e: 2BX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H9\/H10\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: 2-3P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.866 inches (22.00 mm)\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: High-Speed Steel-E-CO (Cobalt HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3944\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039440158750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733947941170,"sku":"9039440158750","price":142.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8523f939d66ed032fa04c37fdf4bd774.jpg?v=1788760126","url":"https:\/\/voomisupply.com\/products\/guhring-9039440158750-thread-forming-tap-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
