Manufactured from high-speed steel (HSS) with a bright\/uncoated finish, it features a plug chamfer for general-purpose through-hole and blind-hole tapping. With 2 flutes and a right-hand thread direction, this tap produces a 3B class of fit thread with an H2 thread limit. Overall length is 2.125 inches, and the thread length is 0.75 inches. Typically installed by machinists, maintenance mechanics, and tooling professionals in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for tapping 8-32 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The plug chamfer style  -  typically 3 to 5 chamfered threads  -  makes it appropriate for most standard tapping applications where the tap enters the workpiece gradually. It is well matched for both hand tapping and machine tapping setups on drill presses, CNC machining centers, and tapping heads where a straight flute geometry is preferred over a spiral design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-32 UNC thread form, right-hand direction, 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent tolerance control in standard thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for use across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer entry for versatile through-hole and shallow blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish  -  no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eStraight flute design suited for short-chipping materials including cast iron and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces requiring 8-32 UNC internal threads at a 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and secure the workpiece before tapping. Use the correct tap drill size for 8-32 UNC threads to ensure proper thread engagement and avoid tap breakage. Apply appropriate cutting fluid for the workpiece material  -  especially when tapping steel  -  to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use; a damaged tap can produce out-of-tolerance threads or seize in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 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\u003eSquare Length\u003c\/strong\u003e: 0.25 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\u003eNeck Length\u003c\/strong\u003e: 1.394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 104\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.014 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: 1068400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743235866930,"sku":"1068400","price":21.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1da596e82c75e75effc801f49d0279dc.jpg?v=1788844332","url":"https:\/\/voomisupply.com\/products\/osg-1068400-straight-flute-tap-8-32-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
