Built from cobalt high-speed steel and finished with a MolyGlide coating, this tap handles the demands of threading aluminum and aluminum alloys with consistent thread quality. It produces a 8-32 UNC right-hand thread to a 2B class of fit, with a modified bottoming chamfer that allows threading close to the bottom of a blind hole. With a 45-degree helix angle and fast flute style, chips are efficiently evacuated upward out of the hole during cutting. Overall length is 2.205 inches.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in machine tapping operations on aluminum and aluminum alloy workpieces, particularly where blind holes require threading near the bottom. The modified bottoming chamfer and fast 45-degree spiral flute geometry make it well-suited for CNC machining centers, drill presses, and tapping attachments in production or job shop environments. It is typically installed and operated by machinists, tool-and-die makers, and precision manufacturing technicians. The H3 and H4 thread limits accommodate standard tolerance requirements for 2B fit fastener applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction provides increased hardness and heat resistance compared to standard HSS taps\u003c\/li\u003e\n\u003cli\u003eMolyGlide finish reduces friction and built-up edge when tapping aluminum alloys\u003c\/li\u003e\n\u003cli\u003e45-degree fast helix angle promotes efficient upward chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer allows threading to within a few threads of the hole bottom\u003c\/li\u003e\n\u003cli\u003eH3 and H4 thread limits support 2B class of fit tolerancing\u003c\/li\u003e\n\u003cli\u003eRight-hand flute and right-hand thread configuration for standard machine tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading of aluminum and aluminum alloy workpieces requiring an 8-32 UNC right-hand thread to a 2B class of fit.

Ensure the workpiece is securely fixtured and the spindle is aligned with the pre-drilled pilot hole before engaging the tap. Use appropriate cutting fluid or lubricant for aluminum even though the MolyGlide finish provides some dry-run capability. Inspect the tap for wear or chipping before each use to avoid thread damage or breakage in the workpiece.\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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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\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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: MolyGlide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3, H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.205 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum and Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3970\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.006 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: 9039700041660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755642880306,"sku":"9039700041660","price":43.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e3baa4abb27101e6641fb01a544a0f0_7e87e97f-ff3f-4dae-8387-75aff44bf55d.jpg?v=1788957488","url":"https:\/\/voomisupply.com\/products\/guhring-9039700041660-spiral-flute-tap-8-32-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
