Built from high speed steel (HSS) with an oxide finish, this plug-style tap features four flutes oriented in a right-hand spiral at a 45-degree helix angle. The spiral flute design evacuates chips upward and out of the hole, making it well-suited for through-hole and blind-hole tapping in ductile metals. At 4.25 inches overall length and weighing 1.94 pounds, it is sized for use in standard tap handles, CNC machining centers, and drill press setups. The H3 thread limit provides a controlled tolerance fit for most standard UNC fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance machining environments where 3\/4-10 UNC threads are required. Typical applications include threading holes in steel, aluminum, cast iron, and similar machinable metals in both shop and field settings. The plug chamfer, with its moderate lead-in, suits through-hole tapping and is the most common tap type for general-purpose work. Machinists, toolmakers, and maintenance mechanics working in industrial, construction, and manufacturing settings will find this tap appropriate for both manual and machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC thread size with right-hand thread direction for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand helix angle promotes efficient chip evacuation in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a broad range of machinable metals\u003c\/li\u003e\n  \u003cli\u003eOxide finish offers mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit delivers controlled tolerance for standard UNC fit classes\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style suits general-purpose through-hole tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/4-10 UNC spiral flute tap compatible with manual tap handles and machine tapping chucks sized for the corresponding tap shank.

Ensure the workpiece is securely fixtured and the tap is properly aligned to the pilot hole before beginning. Apply an appropriate cutting fluid for the workpiece material throughout the operation to extend tool life and improve thread finish. When using in a machine tapping setup, verify spindle speed and feed rate are suitable for the material and tap diameter before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral (Fast)\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: 45 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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.94 pounds\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K033032AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727989342514,"sku":"K033032AS","price":118.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87ec600a6100c819e39842a61a798c70.jpg?v=1788685592","url":"https:\/\/voomisupply.com\/products\/hertel-k033032as-spiral-flute-tap-3-4-10-unc-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
