Built from high-speed steel with a TiN (titanium nitride) coating, this tap delivers improved wear resistance and longer service life compared to uncoated tooling. The bottoming chamfer allows threading close to the bottom of blind holes. With 4 right-hand flutes at a 50-degree helix angle, the spiral geometry pulls chips up and out of the hole during tapping, reducing the risk of chip packing. Overall length is 4.25 inches. This tap is used by machinists, maintenance technicians, and fabricators working in production or repair environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole and blind-hole threading operations on aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The 50-degree helix angle makes it particularly effective in blind holes where chip evacuation is critical. Typical applications include machine shops, MRO facilities, and field repair work where 3\/4-10 UNC fastener holes must be cut or restored. Thread limit is H3, appropriate for standard tolerance threading in most steel and iron applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form, right-hand thread and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes at 50-degree helix angle for efficient chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for standard tolerance fit on most steel and cast iron workpieces\u003c\/li\u003e\n\u003cli\u003e4.25-inch overall length with 0.59-inch shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 3\/4-10 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Ensure the workpiece is properly secured before tapping and that the correct cutting fluid for the workpiece material is applied. Never reverse a spiral flute tap under power without confirming the machine spindle direction, as incorrect reversal can break the tap in the hole. Inspect the tap for wear or chipping before each use.\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\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 10\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\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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: 0.465 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\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: 1433705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751657865522,"sku":"1433705","price":225.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8402910a927fad46ca4319b09d4b9341_2b248994-907c-4cb2-8c1f-5e1620ec20aa.jpg?v=1788924042","url":"https:\/\/voomisupply.com\/products\/osg-1433705-spiral-flute-tap-3-4-10-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
