It features an 8-32 UNC thread form with a plug chamfer, 2 flutes, and a 2B class of fit to meet standard fastener tolerances. The tap is manufactured from high-speed steel and finished with a steam oxide coating that reduces friction and helps resist corrosion during use. With an H3 thread limit, it holds tight dimensional consistency for production threading work. Licensed machinists, maintenance technicians, and metalworking trades use this tap for tapping ferrous and non-ferrous materials in general-purpose and production environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The spiral point design pushes chips forward ahead of the cutting zone, making it well-suited for continuous-feed and CNC tapping operations where chip evacuation is critical. Its compact overall length of 2.125 inches makes it practical in benchtop drill presses, CNC machining centers, and hand-tap handles on production floors and field service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form with 2B class of fit for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for standard through-hole tapping entry\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for consistent dimensional accuracy across production runs\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel.

Before tapping, ensure the workpiece is secured and the pilot hole is drilled to the correct tap drill size for 8-32 UNC. Apply appropriate cutting fluid for the material being tapped. When used in powered equipment, verify spindle speed and feed rate are appropriate for the material and tap size to avoid breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 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: 0.014 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 287\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: 2885301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738622624050,"sku":"2885301","price":19.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad692a438a13db33ed204f66349347a3.jpg?v=1788801940","url":"https:\/\/voomisupply.com\/products\/osg-2885301-spiral-point-tap-8-32-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
