Built from high-speed steel (HSS) with a bright, uncoated finish, it features 4 right-hand flutes with a 50-degree helix angle that efficiently evacuates chips upward out of the hole during through-hole and blind-hole tapping operations. The plug chamfer provides a gradual thread lead-in, making it well suited for general-purpose production tapping. The tap carries an H3 thread limit designation, indicating a controlled oversize tolerance appropriate for standard UNC fit classes. It measures 4.25 inches overall length and is intended for use in CNC machining centers, manual lathes, or drill press tapping setups.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The spiral flute geometry promotes consistent chip flow in both through-hole and blind-hole applications, reducing the likelihood of chip packing that is common with straight-flute taps. It is a practical choice for machine shops, maintenance facilities, and field fabrication work where 3\/4-10 UNC threaded holes are required across a variety of base metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form with right-hand thread direction and H3 thread limit\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes at 50-degree helix angle for efficient upward chip evacuation\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for gradual thread engagement in standard tapping applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction suitable for aluminum, cast iron, and carbon steel workpieces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; no coolant-through feature\u003c\/li\u003e\n\u003cli\u003e4.25 inches overall length with 1.24 inches thread length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 3\/4-10 UNC spiral flute plug tap compatible with standard tap holders and tapping heads sized for the 0.59-inch shank diameter.

Secure the workpiece fully before beginning the tapping operation and ensure the tap is held in a rigid, properly aligned holder to prevent tap breakage. Always apply an appropriate cutting fluid or tapping compound for the workpiece material. Follow shop safety practices and relevant OSHA machine guarding standards when operating tapping equipment.\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\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees\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: H3\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.24 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\u003eNeck Length\u003c\/strong\u003e: 2.429 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\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: 1433600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740802285874,"sku":"1433600","price":200.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba9f37f0c6274e26120430657bcaebbe.jpg?v=1788827511","url":"https:\/\/voomisupply.com\/products\/osg-1433600-spiral-flute-tap-3-4-10-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
