It features three flutes and a plug chamfer, which allows the tap to start easily in a through-hole and push chips forward ahead of the cutting edge rather than packing them in the flute. The body is ground from 3 percent vanadium high-speed steel, providing increased wear resistance and edge retention over standard M2 HSS when tapping alloy and carbon steels. Overall length is 3.1563 inches with a thread length of 25 millimeters and a shank diameter of 8.20 millimeters. The bright, uncoated finish suits general-purpose applications where no specialized coating is required.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance machining environments where 7\/16-14 UNC internal threads are required in steel. Typical applications include threading drilled-through holes in structural components, brackets, fixtures, and general fabrication work. The spiral point geometry makes it most effective in through-hole applications where chip ejection is critical to thread quality and tool life. It is used in manual tap handles, drill press setups, and CNC tapping cycles with rigid or floating tap holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole tapping in steel\u003c\/li\u003e\n\u003cli\u003e3 percent vanadium high-speed steel construction for improved wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides easy starting and full thread form over the chamfer length\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for consistent fit within standard tolerance ranges\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose steel tapping applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 7\/16-14 UNC through-holes in steel materials.

Apply appropriate cutting fluid or tapping compound when threading steel to extend tool life and improve thread finish. For CNC applications, verify spindle speed and feed rate match the tool manufacturer recommendations for the material and tap size. Inspect the tap for wear or chipping regularly, as a damaged tap can produce out-of-tolerance threads or break in the hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 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 Type\u003c\/strong\u003e: Plug\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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.1563 inches (80.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 3% Vanadium 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T2640525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727564702002,"sku":"T2640525","price":45.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96226053a7d54fcce5ca3f914309375c.jpg?v=1788679438","url":"https:\/\/voomisupply.com\/products\/accupro-t2640525-spiral-point-tap-7-16-14-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
