Built from HSS-E cobalt high-speed steel, it delivers the heat and wear resistance needed for production tapping and repetitive use. The plug chamfer distributes cutting load gradually over the first few threads, making it well suited for through-hole applications where the tap can feed chips forward ahead of the cut. With a 6-40 UNF thread profile, 3 flutes, a 2B class of fit, and a thread limit of H2\/H3, this tap produces consistent, tolerance-controlled threads in light-duty fastener holes common in precision assemblies and instrumentation work.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in through-hole threading operations on steel workpieces. It is suited for machine tapping on CNC mills, drill presses, and tapping heads in both job shop and production environments. The 6-40 UNF size is common in electronics enclosures, instrument panels, and small mechanical assemblies where fine-thread engagement is required in limited material thickness. The H2\/H3 thread limit supports standard 2B fit tolerances for general-purpose unified fine-thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS-E cobalt construction provides elevated heat resistance for tapping steel and harder ferrous alloys\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, keeping flutes clear in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load over several threads for smoother entry and reduced tap breakage risk\u003c\/li\u003e\n  \u003cli\u003eH2\/H3 thread limit holds 2B class of fit tolerances for standard UNF fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows visual wear inspection and suits a wide range of cutting fluids\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3-flute design balances chip clearance with thread form support in small-diameter tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for through-hole 6-40 UNF threading applications in steel.

Secure the workpiece firmly and ensure the tap is aligned perpendicular to the hole to prevent thread distortion or breakage. Apply an appropriate cutting fluid for steel before and during the tapping operation. Do not reverse the tap under power without confirming the machine or tapping head is equipped for synchronized reversing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 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: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\/H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.025 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: 3902\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 9039020035050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731590873394,"sku":"9039020035050","price":34.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9dcc45d8d24f27d785a46f16c9fbfd1_6a9ab531-1645-4a8e-85ef-647071c32196.jpg?v=1788732932","url":"https:\/\/voomisupply.com\/products\/guhring-9039020035050-spiral-point-tap-6-40-unf-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
