It cuts a 3\/8-16 UNC right-hand internal thread to a 2B class of fit, with an H3 thread limit for controlled tolerance. Made from high speed steel with a bright finish, this three-flute tap drives chips forward ahead of the cutting zone, which makes it well suited for through-hole applications where chip evacuation is critical. Overall length is 2.938 inches with a thread length of 1.25 inches. Licensed machinists, tool and die makers, and maintenance technicians are the typical users.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. It fits standard CNC tapping heads, hand tap wrenches, and tapping attachments that accept a 0.381-inch shank diameter. The plug chamfer with 3-5 lead threads makes thread starting straightforward in production and repair tapping operations on through-hole workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form, right-hand cut, 2B class of fit\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent tolerance control\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles aluminum and low-to-medium carbon steel\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides easy thread entry without requiring a starter tap\u003c\/li\u003e\n  \u003cli\u003eBright finish — no coating that could affect thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel.

Power down or de-energize any CNC or powered tapping equipment before changing tooling. Use the appropriate cutting fluid for the material being tapped — dry tapping in steel is not recommended. Follow shop safety practices and applicable OSHA machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\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\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.25 inches (0.787 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\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\u003eSeries\u003c\/strong\u003e: 287\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.078 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2886000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739134656818,"sku":"2886000","price":22.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9663a27b8afcdbd9ab9bca82013888a6.jpg?v=1788810009","url":"https:\/\/voomisupply.com\/products\/osg-2886000-spiral-point-tap-3-8-16-unc-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
