Built from vanadium high-speed steel with an oxide finish, it provides solid wear resistance and chip control under production tapping conditions. The spiral point geometry pushes chips ahead of the tap and out of the hole, reducing clogging and breakage risk. With 3 flutes, an H2 thread limit, and a plug chamfer, it suits general-purpose through-hole tapping where thread accuracy and tool life are the priority. Overall length is 2.382 inches with a thread length of 0.44 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in machining, maintenance, repair, and fabrication environments where 8-32 UNC threads are required. It fits standard tapping operations on steel, aluminum, and similar materials in through-hole configurations. The plug chamfer requires some starting clearance, making it appropriate for holes that pass fully through the workpiece. Machinists, tool-and-die technicians, and maintenance mechanics commonly use this tap on manual machines and CNC tapping centers alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward through the hole, reducing packing and tap breakage\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction provides elevated heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eOxide finish improves lubricity and corrosion resistance during operation\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3-5 lead threads for through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for close-tolerance 8-32 UNC threads\u003c\/li\u003e\n\u003cli\u003e3 flutes balance chip clearance with core strength at this thread size\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for 8-32 UNC through-hole tapping operations in standard tap holders, collet chucks, and tapping attachments accepting a 0.22-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUse the correct tap drill size for 8-32 UNC threads before tapping and ensure the workpiece is securely fixtured. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Power down any machine spindle and confirm zero rotation before loading or unloading the tap. Follow applicable shop safety procedures and manufacturer recommendations for tapping speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.382 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.28125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 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\u003eSeries\u003c\/strong\u003e: 301\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1712801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742872338738,"sku":"1712801","price":45.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96a0ffe38ae8a2c771d4005f489d4303.jpg?v=1788840067","url":"https:\/\/voomisupply.com\/products\/osg-1712801-spiral-point-sti-tap-8-32-unc-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
