It cuts a 1\/4-20 UNC right-hand thread with a plug chamfer entry, making it well suited for production tapping in CNC or hand-tapping applications where the chip is pushed ahead of the tap rather than back through the flutes. Manufactured from HSS-E cobalt high-speed steel, it delivers improved heat and wear resistance over standard HSS. The bright, uncoated finish is compatible with standard cutting fluids. This tap is used by machinists, maintenance technicians, and trade professionals working in metal fabrication, mechanical assembly, and equipment repair.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading applications in ferrous materials, primarily steel. The plug chamfer provides a gradual cutting entry suitable for both new thread production and replacement threading in structural and mechanical assemblies. With a 2B class of fit, the threads it produces meet standard tolerance requirements for most bolted connections and fastener assemblies encountered in HVAC equipment, plumbing hardware, electrical enclosures, and general mechanical work. The H4\/H5 thread limit designation ensures consistent oversize control for reliable thread engagement across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, keeping the flutes clear during through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt construction resists heat buildup in steel and harder ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows gradual thread entry for controlled cutting action\u003c\/li\u003e\n  \u003cli\u003e2B class of fit meets standard tolerance requirements for general fastener assemblies\u003c\/li\u003e\n  \u003cli\u003eH4\/H5 thread limit provides consistent oversize control across production use\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish works with a wide range of standard cutting oils and fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of 1\/4-20 UNC right-hand threads in steel.

Always apply an appropriate cutting fluid to reduce friction and extend tool life. Ensure the workpiece is securely fixtured before tapping to prevent thread misalignment. Do not reverse the tap aggressively to avoid breakage in harder materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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: H4\/H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.551 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\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3901\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: 9039010063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727240200498,"sku":"9039010063500","price":37.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9dcc45d8d24f27d785a46f16c9fbfd1.jpg?v=1788675230","url":"https:\/\/voomisupply.com\/products\/guhring-9039010063500-spiral-point-tap-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
