Built from 3% Vanadium High Speed Steel (HSS), this tap delivers increased wear resistance and toughness compared to standard M2 HSS, making it well-suited for production tapping in steels. It carries a plug chamfer (approximately 3-5 lead threads) for guided entry in through-hole applications and a 2B class of fit for standard commercial thread tolerances. The bright finish indicates no additional coating, keeping the profile close to ground dimensions. Overall length is 3.38 inches with a 29 mm thread length, and the shank diameter is 9.32 mm. Right-hand cut. This tap is a direct-drive tool installed by machinists and maintenance trades using a tap handle, drill press, or CNC tapping head.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole tapping operations in steels at 1\/2-13 UNC. The spiral point geometry pushes chips ahead of the tap rather than packing them into the flute gullets, which makes it the preferred choice for through-hole production work over hand tapping or bottoming scenarios. It is not designed for blind holes where chip evacuation is restricted. Typical applications include threading holes in steel plate, structural fabrication, machine frames, and general maintenance work requiring 1\/2-13 fastener engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread form, right-hand cut, 2B class of fit\u003c\/li\u003e\n\u003cli\u003e3% Vanadium HSS construction for improved wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole tapping\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (approximately 3-5 lead threads) for guided thread entry\u003c\/li\u003e\n\u003cli\u003e3 flutes provide chip clearance and cutting stability\u003c\/li\u003e\n\u003cli\u003eBright finish, no coating — ground to close dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping through-hole 1\/2-13 UNC threads in steels; suitable for use with standard tap handles, drill press tap chucks, and CNC tapping heads accepting a 9.32 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a qualified machinist or maintenance technician using the appropriate tap wrench, machine chuck, or tapping head rated for the shank diameter. Always ensure the workpiece is securely clamped and the tap is properly aligned axially before engagement to prevent tap breakage. Use a cutting fluid appropriate for steel to extend tool life and maintain thread quality. Do not use this tap in blind holes where chip evacuation cannot be maintained.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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\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\u003eMaterial\u003c\/strong\u003e: 3% Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright (uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.38 inches (85.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.32 mm\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\u003eMaterial Application\u003c\/strong\u003e: Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: T2640562B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730893898034,"sku":"T2640562B","price":82.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/190e845461fbccbf1a2180ba0c1346e8.jpg?v=1788724471","url":"https:\/\/voomisupply.com\/products\/accupro-t2640562b-spiral-point-tap-1-2-13-3-flute-2b","provider":"Voomi Supply","version":"1.0","type":"link"}
