It drives chips forward ahead of the cutting edge, keeping the flutes clear and allowing use in through-hole applications without frequent withdrawal. Built from high-speed steel (HSS) with a steam oxide finish, this tap provides moderate lubricity and corrosion resistance suited to general shop and field use. The 2-flute geometry and plug chamfer make it a standard choice for production and maintenance threading where consistent 2B class of fit is required. Overall length is 2.375 inches with a thread length of 0.58 inches and a shank diameter of 0.22 inches.\u003c\/p\u003e\u003cp\u003eThis tap is intended for threading through-holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The plug chamfer style requires a few thread lead-in before full cutting begins, making it suitable for through-holes rather than blind bores. Typical install scenarios include maintenance and repair work, OEM fabrication, and production threading where a 12-24 UNC 2B fit is specified. The right-hand thread direction matches standard fastener orientation. No coolant-through capability is present, so conventional flood coolant or cutting oil applied at the entry point is the preferred lubrication method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry drives chips forward, ideal for through-hole threading\u003c\/li\u003e\n\u003cli\u003e12-24 UNC thread form with 2B class of fit for standard fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness across a range of workpiece hardnesses\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating adds surface lubricity and reduces galling tendency\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) for efficient full-depth thread cutting in through-holes\u003c\/li\u003e\n\u003cli\u003eRight-hand, 2-flute design in a compact 2.375-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 12-24 UNC through-holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces where a 2B class of fit is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists, maintenance technicians, and skilled tradespeople using a tap wrench, tapping head, or CNC rigid-tapping cycle. Always secure the workpiece and ensure the tap is started square to the hole axis to prevent tap breakage. Apply cutting oil or appropriate tapping fluid before and during the operation; do not run dry on steel. Inspect the tap for wear or chipping before each use, as a damaged cutting edge on a small-diameter tap can lead to breakage and difficult extraction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24 UNC\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.58 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.023 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: 2886801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728354541874,"sku":"2886801","price":21.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e7c388058b6d2fe150193aec660a427.jpg?v=1788690614","url":"https:\/\/voomisupply.com\/products\/osg-2886801-spiral-point-tap-12-24-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
