It cuts an 8-32 UNC right-hand thread to a 2B class of fit and carries both H3 and H4 thread limits for controlled tolerance output. The tap is manufactured from cobalt with a bright, uncoated finish. Its 45-degree helix angle and fast flute style are well suited to pulling chips up and out of the hole during the tapping cycle. Overall length is 2.13 inches. This tool is installed by machinists, toolroom technicians, and maintenance trades working with threaded fastener applications.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading operations where chip evacuation is critical to thread quality and tap life. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug or taper chamfer. With a 45-degree helix angle and fast flute geometry, it handles softer, gummy materials such as aluminum and aluminum alloys efficiently. It is part of the GUHRING Series 3931 and is packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer for threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle with fast flute style for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eCobalt construction for increased heat and wear resistance versus high-speed steel\u003c\/li\u003e\n\u003cli\u003eH3 and H4 thread limits for precise tolerance control\u003c\/li\u003e\n\u003cli\u003e2B class of fit meets standard commercial thread tolerance requirements\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with cutting fluids used in aluminum applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in aluminum and aluminum alloy.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the threading cycle. Use a cutting fluid or tapping compound suitable for the workpiece material to extend tool life and improve thread finish. Always power down and lock out the machine before manually handling or changing the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3, H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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, Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.827 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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: 3931\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 9039310041660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727195210034,"sku":"9039310041660","price":40.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60e78b48a1d1bf47cddec46a7114de0f.jpg?v=1788674571","url":"https:\/\/voomisupply.com\/products\/guhring-9039310041660-spiral-flute-tap-8-32-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
