Built from cobalt high-speed steel with a bright, uncoated finish, this tap features a 40-degree helix angle that efficiently evacuates chips back through the flute during operation. The modified bottoming chamfer allows threading close to the bottom of a blind hole. At 3.381 inches overall length with a 0.367-inch shank diameter, it is sized for standard machine tap holders and CNC tapping attachments. Licensed machinists and tool-and-die technicians are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and job-shop environments where blind-hole threading is required in aluminum and other non-ferrous metals, gray cast iron, malleable iron, spheroidal iron, and steel. The fast flute style and right-hand spiral geometry make it well-matched to CNC machining centers and tapping machines running right-hand threads at moderate to high feed rates. The 1\/2-13 UNC thread form and 2B class of fit are standard across a broad range of mechanical assemblies in industrial, automotive, and general fabrication applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt HSS construction provides heat and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes reliable chip evacuation in blind-hole applications\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer enables threading closer to hole bottom compared to standard taper or plug chamfers\u003c\/li\u003e\n\u003cli\u003e2B class of fit delivers the standard thread tolerance required for most general-purpose mechanical fastening\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish is compatible with a wide variety of cutting fluids and coolants\u003c\/li\u003e\n\u003cli\u003eRight-hand flute and right-hand thread orientation for conventional tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard machine tap holders and CNC tapping attachments accepting a 0.367-inch shank diameter; suitable for blind-hole threading operations producing 1\/2-13 UNC, 2B class of fit internal threads in aluminum and other non-ferrous metals, gray cast iron, malleable iron, spheroidal iron, and steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a qualified machinist following shop safety procedures. Ensure the spindle and workpiece are secured before engaging the tap, and confirm the tap holder torque settings are appropriate for the material being threaded. Coolant-through is not supported on this tap, so external cutting fluid application is recommended to extend tool life and improve thread quality. Always verify hole depth and pilot hole diameter before beginning the tapping cycle to avoid tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum and Other Non-Ferrous Metal; Gray Cast Iron; Malleable and Spheroidal Iron; Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.381 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9039040127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729105027378,"sku":"9039040127000","price":88.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30f387cde11ed4cc287767b35737c0a2.jpg?v=1788700049","url":"https:\/\/voomisupply.com\/products\/guhring-9039040127000-spiral-flute-tap-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
