Built from high-speed steel with an oxide coating, this tap features 4 right-hand flutes with a 45-degree helix angle and a fast flute style that evacuates chips efficiently during the tapping cycle. At 4.25 inches overall length, it is suited for use in drill presses, CNC machining centers, and manual tapping setups. The bottoming chamfer allows threading closer to the bottom of a blind hole than plug or taper style taps. Licensed machinists, tool-and-die workers, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is intended for threading steel, cast iron, aluminum, and similar machinable materials in both production and maintenance-repair-operations environments. The H3 thread limit designates a controlled oversize tolerance appropriate for standard UNC fit classes. The oxide finish provides a degree of surface hardness and lubricity to reduce galling during cutting. No coolant-through capability is present, so flood or brush-applied cutting fluid is recommended for best tool life and thread quality in ferrous materials.\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\u003eBottoming chamfer style for threading to near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle with fast flute style for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for standard UNC tolerance class fitment\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e4 flutes for balanced cutting load in medium to hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for any application requiring a 3\/4-10 UNC bottoming tap in standard H3 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by qualified machinists or maintenance technicians using a tap wrench, drill press, or CNC tapping cycle with appropriate speed and feed parameters for the workpiece material. Always ensure the pilot hole is drilled to the correct tap drill diameter for 3\/4-10 UNC before tapping. Apply cutting fluid generously, particularly when tapping ferrous materials, to reduce heat buildup and extend tap life. Never force a tap through an undersized or misaligned hole, as this is the primary cause of tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.93 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: K033033AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728411885874,"sku":"K033033AS","price":185.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b786d7d44b7429ee06dc2fa5f72c1f13.jpg?v=1788690940","url":"https:\/\/voomisupply.com\/products\/hertel-k033033as-spiral-flute-tap-3-4-10-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
