The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for production tapping in steel and similar materials where chip evacuation is critical. Built from 3% vanadium high-speed steel, this tap delivers improved wear resistance and edge retention compared to standard M2 HSS. It carries an H5 thread limit and a bright, uncoated finish. Overall length is 2.7188 inches with a thread length of approximately 0.866 inches (22 mm). This tap is installed by machinists and toolroom technicians on CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in steel and comparable ferrous materials in through-hole tapping operations. The plug chamfer, with its moderate lead, is the standard choice for most production and general-purpose tapping work where the tap can pass completely through the workpiece. It is commonly used in manufacturing, maintenance, and repair environments that require accurate, repeatable UNF threaded holes in light to medium carbon steel stock. The 3-flute configuration provides a balance of chip room and thread support suitable for these material applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips forward for efficient through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3% vanadium high-speed steel construction for extended tool life in steel applications\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for controlled tolerance fit in precision threading work\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a versatile lead suitable for most general-purpose through-hole jobs\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of tapping fluids and coolants\u003c\/li\u003e\n\u003cli\u003eRight-hand thread cutting, 3 flutes, 5\/16-24 UNF thread form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in through-hole tapping of steel workpieces requiring 5\/16-24 UNF threads.

Always ensure the tap is properly aligned with the drilled pilot hole before engagement to prevent tap breakage. Use an appropriate cutting fluid or tapping compound rated for the workpiece material to protect the cutting edges and improve thread finish. Inspect tap condition before each use and replace at the first sign of wear or chipping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 UNF\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\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7188 inches (69.06 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.866 inches (22 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches (8.08 mm)\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: 0.14 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: T2640465\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730502680882,"sku":"T2640465","price":37.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/887d158a5beadb26c56d803c075f924b.jpg?v=1788718609","url":"https:\/\/voomisupply.com\/products\/accupro-t2640465-spiral-point-tap-5-16-24-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
