Built from cobalt high-speed steel with a TiN (titanium nitride) coating, it delivers extended tool life in demanding cutting applications. The plug chamfer geometry drives chips forward ahead of the tap, keeping the flutes clear during through-hole work. With a 5\/8-11 UNC thread profile, 4 flutes, and an H11 thread limit, this tap is suited for machinists and maintenance technicians working on production or repair threading tasks where tight tolerance and consistent thread form are required.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading applications across a broad range of workpiece materials including aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel. The spiral point design is most effective in through-hole setups where chips can exit freely ahead of the cutting face. It is appropriate for use in CNC machining centers, drill presses, and manual tapping operations where a plug-chamfer entry is preferred. Coolant-through capability is not present on this tap, so external coolant or cutting fluid application is recommended when tapping harder materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form with H11 thread limit for controlled oversize fit\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) suits through-hole threading and general-purpose entry\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides chip control and stability in a range of material hardnesses\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; fits standard right-hand tapping chucks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in aluminum, gray cast iron, malleable iron, spheroidal iron, non-ferrous metals, stainless steel, and steel.

Secure the workpiece fully before tapping and ensure the tap is properly aligned to prevent tap breakage or cross-threading. Apply appropriate cutting fluid or tapping compound for the workpiece material, particularly when working with stainless steel or cast iron. Replace worn taps promptly; running a dull tap in harder materials increases the risk of breakage and thread damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmount Oversize\u003c\/strong\u003e: 0.005 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: 3986\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.109 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: 9039860158750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734041821490,"sku":"9039860158750","price":79.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f80e66bd16877b81f97d1171902e8c77.jpg?v=1788760626","url":"https:\/\/voomisupply.com\/products\/guhring-9039860158750-spiral-point-tap-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
