It cuts a 7\/16-20 UNF right-hand internal thread and uses a plug chamfer to guide entry and distribute cutting load across the leading threads. The tap is manufactured from HSS-E cobalt high-speed steel for improved heat and wear resistance compared to standard HSS. A steam oxide coating reduces friction and helps resist galling during the tapping cycle. With a thread limit of H5 and a class of fit rating of 2B\/3B, this tap produces threads within tight commercial and precision tolerances. Machinists and maintenance technicians install it in drill presses, CNC machining centers, and hand-tapping setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading applications in steel workpieces, including structural steel, mild steel, and similar ferrous materials. The spiral point design pushes chips forward ahead of the tap rather than packing them in the flutes, making it well matched to through-hole work where chip evacuation is straightforward. At 3.1610 inches overall length with a 0.8660-inch thread length and 0.3230-inch shank diameter, it fits standard tap holders and collet chucks sized for 7\/16 taps. It is sold individually and is part of the GUHRING Series 4405 lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-20 UNF thread form, right-hand cut, Class 2B\/3B fit\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt construction for increased heat resistance and tool life in steel\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and resists galling\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across several leading threads for controlled entry\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for consistent, close-tolerance thread production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel.

Ensure the tap is aligned perpendicular to the workpiece surface before engagement to avoid bell-mouthed or torn threads. Apply cutting fluid rated for ferrous materials throughout the tapping cycle. Always de-energize and lock out machine power before changing or inspecting taps in powered equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 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: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.8660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3230 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.05 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: 4405\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9044053111130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747457925426,"sku":"9044053111130","price":33.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5823e58e2818e435441a1a6d669ebd3b_2d2f4d30-91ef-4a50-b04c-48db5ba0556e.jpg?v=1788880495","url":"https:\/\/voomisupply.com\/products\/guhring-9044053111130-spiral-point-tap-7-16-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
