It features a 45-degree helix angle that efficiently evacuates chips up and out of the hole, making it well suited for blind-hole tapping where chip packing is a concern. The tap is ground to an H3 thread limit for consistent dimensional control and carries a steam oxide coating that reduces friction and improves lubrication retention during cutting. Overall length is 4.25 inches. Installation is performed by machinists and toolroom technicians in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel. The modified bottoming chamfer allows threading close to the bottom of a blind hole while still providing enough lead to start the tap reliably. The spiral flute geometry and right-hand thread direction make it compatible with standard CNC tapping cycles and hand tapping in right-hand drilling machines. It is a single-piece unit sold individually, suited for low-volume job shop work as well as production runs where dimensional accuracy on 3\/4-10 UNC threads is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree right-hand spiral flute for upward chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for tight dimensional tolerances on 3\/4-10 UNC threads\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and aids lubrication retention\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction for wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction compatible with standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 3\/4-10 UNC right-hand internal threads in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a properly sized tap holder or collet chuck rated for the shank diameter before use. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 3\/4-10 UNC before beginning the tapping operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Never force a tap that has stalled; back it out carefully 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\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: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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: Vanadium High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam 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\u003eThread Length\u003c\/strong\u003e: 0.799 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: 2.433 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: 290\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.277 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: 2933601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731018514738,"sku":"2933601","price":216.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56a5aca6df995a85167e4a024df3ee1b.jpg?v=1788725922","url":"https:\/\/voomisupply.com\/products\/osg-2933601-spiral-flute-tap-3-4-10-unc-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
