Built from vanadium high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life in demanding production and maintenance applications. The modified bottoming chamfer allows threading close to the bottom of blind holes. Three right-hand spiral flutes at a 45-degree helix angle evacuate chips up and out of the hole, reducing the risk of chip packing in interrupted cuts and deep-hole applications. Machinists and toolroom technicians install this tap by hand or with a tapping head on a drill press or CNC machining center.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations on ferrous metals in both job shop and production environments. The 3B class of fit produces a standard tolerance thread compatible with commercial fastener assemblies. The H3 thread limit designation indicates a ground thread profile held to close tolerances, making it appropriate for precision assemblies where consistent thread engagement is required. It is sold individually and sized for use in general-purpose tapping fixtures as well as manual tap wrenches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-14 UNC thread size with H3 thread limit for close-tolerance ground threads\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral flutes promote upward chip evacuation in blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction resists wear in stainless and carbon steel materials\u003c\/li\u003e\n  \u003cli\u003e3B class of fit for standard commercial thread assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel.

Power down or disengage the machine spindle before loading the tap into the holder. Use a cutting fluid rated for the workpiece material — sulfur-based or synthetic cutting oils are common for steel applications. Inspect the tap for chipping or wear before each use and do not force a worn tap, as breakage in a blind hole is difficult to recover.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 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: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eThread 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\u003eOverall Length\u003c\/strong\u003e: 3-5\/32 inches (2.719 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.571 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\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\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1733205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749651120434,"sku":"1733205","price":79.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71aa861f03b3400ac353566983c39113_c97386d1-5151-4650-8c7d-3ea4960e12d0.jpg?v=1788908797","url":"https:\/\/voomisupply.com\/products\/osg-1733205-spiral-flute-tap-7-16-14-unc-tin-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
