Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent thread form across general-purpose tapping applications. The plug chamfer  -  typically 3 to 5 threads  -  allows for easy starting in through-holes and blind holes with sufficient depth. With 4 flutes and an H1 thread limit, the tap holds tight tolerance and is suited for production and maintenance threading work performed by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis tap is intended for tapping operations in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It fits standard tap holders, tapping heads, and CNC machine spindles that accept 3\/4-10 tooling. The straight flute design works best in shorter-chipping materials where flute packing is not a concern. It is well suited for both manual tapping and machine tapping setups in job shop, maintenance, and light production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for easy thread entry in through-holes and adequately deep blind holes\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for rigidity and support in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eH1 thread limit for close-tolerance thread production\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish  -  no additional coating variables affecting tap-hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production straight flute plug tap for 3\/4-10 UNC threading applications in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the workpiece fully before tapping and ensure the tap is aligned perpendicular to the work surface to prevent thread lead errors. Power down and de-energize any machine tool before installing or removing the tap from the holder. Use appropriate cutting fluid for the workpiece material  -  sulfurized oil for steels, a light cutting fluid for aluminum. Do not force a tap that has stopped advancing; back off to clear chips before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.2247 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\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\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: 1008900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743207588146,"sku":"1008900","price":101.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6e73b85bfedd14a5730ce1cfd553974.jpg?v=1788843959","url":"https:\/\/voomisupply.com\/products\/osg-1008900-straight-flute-tap-3-4-10-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
