Manufactured from 3% vanadium high speed steel, this plug-chamfer tap provides increased wear resistance and edge retention compared to standard HSS. The spiral point geometry pushes chips forward ahead of the cutting action, making it well suited for through-hole tapping where chip evacuation is critical. With an overall length of 3.156 inches (80.17 mm) and a 25 mm thread length, the T2670543 carries an H3 thread limit and a bright finish. It is installed by machinists and toolroom technicians using standard tapping equipment.\u003c\/p\u003e\u003cp\u003eThis tap is designed for tapping through holes in aluminum workpieces where a clean, accurate unified fine thread is required. The plug chamfer, with its moderate lead-in, suits both machine tapping and careful hand tapping operations. The H3 thread limit designation indicates a controlled oversize tolerance appropriate for producing standard-fit threads in softer non-ferrous materials. At 0.17 pounds, the tap is a single-piece unit packaged individually, making it practical for shop floor restocking or one-off tooling orders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimizing performance in through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved wear resistance and edge life\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides moderate lead-in suited to both machine and hand tapping\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for accurate, standard-fit 7\/16-20 UNF threads\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating, allowing visual inspection of the tool edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 3-flute design optimized for aluminum material applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 7\/16-20 unified fine thread through holes in aluminum.

Ensure the spindle speed and feed rate are appropriate for the workpiece material and tap diameter before starting the cut. Use a suitable cutting fluid or tapping lubricant even in aluminum to extend tool life and improve thread finish. Inspect the tap for chipping or wear before each use and replace if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (3% Vanadium HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.156 inches (80.17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 25 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\u003eCoolant Through\u003c\/strong\u003e: No\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: T2670543\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734645539122,"sku":"T2670543","price":64.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5777e7cdb1109328333b6892f3a7af95_4e43c91f-e3ae-4819-88ac-289f8642f736.jpg?v=1788764338","url":"https:\/\/voomisupply.com\/products\/accupro-t2670543-spiral-point-tap-7-16-20-3-flutes-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
