It features a plug chamfer, three flutes, and a right-hand thread direction. Built from HSS-E vanadium high speed steel with an oxide finish, this tap handles a wide range of ferrous and non-ferrous materials where toughness and edge retention matter. With an H5 thread limit, it holds tight tolerances suitable for precision threading work. Overall length is 2.937 inches with a thread length of 0.945 inches. Machinists and tool-room technicians use this tap in production and maintenance environments alike.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading in manual, CNC, and automatic tapping setups where chip ejection forward is preferred over chip evacuation backward. The spiral point geometry pushes chips ahead of the cut, reducing jamming risk and allowing higher feed rates compared to hand-tap styles. It is a standard choice for threading steel, cast iron, and similar materials in general machining, automotive, and MRO applications. Coolant-through capability is not included in this configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread size for fine-pitch through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHSS-E vanadium high speed steel construction for improved toughness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild lubricity and corrosion resistance during service\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) eases entry and distributes cutting load across multiple threads\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for controlled tolerance fit in precision threading work\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry ejects chips forward, keeping flutes clear in through-hole cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, standard for the majority of threaded fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use spiral point tap compatible with standard 3\/8-inch tap holder collets and tapping heads accepting a 0.381-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed by a qualified machinist familiar with threading operations and proper speeds and feeds for the workpiece material. Always secure the tap in a properly sized collet or tap holder to prevent runout and breakage. Ensure the workpiece is rigidly clamped and the pilot hole is drilled to the correct tap drill size for 3\/8-24 UNF threads before tapping. Apply an appropriate cutting fluid for the material being threaded to extend tap life and improve thread finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 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: HSS-E Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.25 inches\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: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: T1640505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754513334578,"sku":"T1640505","price":32.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65e7860995bdceb317e355137528ed9f.jpg?v=1788946193","url":"https:\/\/voomisupply.com\/products\/accupro-t1640505-spiral-point-tap-3-8-24-plug-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
