Built from high-speed steel with a titanium nitride (TiN) coating, this tap is suited for production threading where wear resistance and surface hardness are critical. The three-flute spiral point geometry pushes chips ahead of the cutting zone, keeping the flutes clear during deeper through-hole passes. An H3 thread limit provides a controlled fit tolerance appropriate for standard UNC fastener engagement. Licensed HVAC, plumbing, electrical, and industrial maintenance technicians will recognize this tap as a dependable tool for field and shop threading operations.\u003c\/p\u003e\u003cp\u003eThis tap is designed for through-hole threading in a wide range of materials. Rated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel, the 1233605 covers a broad spectrum of materials encountered in mechanical, HVAC equipment, and industrial maintenance work. The plug chamfer — typically 3 to 5 chamfered threads — starts the tap easily and distributes cutting load across the lead threads, making it suitable for both hand tapping and machine tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form, right-hand spiral point plug configuration\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral point geometry pushes chips forward through the hole\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for controlled fit tolerance on standard UNC threads\u003c\/li\u003e\n\u003cli\u003eRated for aluminum, cast iron, low-, medium-, and high-carbon steel, and hardened steel\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — compatible with standard cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production spiral point plug tap for 3\/4-10 UNC through-hole threading applications across aluminum, cast iron, and carbon steel workpieces in OSG Series 105.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or maintenance technicians familiar with tapping procedures and cutting tool safety. Secure the workpiece and ensure the tap is properly aligned with the hole axis before applying torque — misalignment is a primary cause of tap breakage in larger-diameter taps. Apply appropriate cutting fluid for the workpiece material; hardened steel and cast iron require attention to speed and lubrication. For machine tapping, verify spindle speed and feed rate are set for the material and tap diameter before starting the cut.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/strong\u003e: TiN (Titanium Nitride)\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: 1.22 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.321 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Hardened Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 1233605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754668654898,"sku":"1233605","price":141.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8629ed6992cf4de999425b579b3cda6a.jpg?v=1788947665","url":"https:\/\/voomisupply.com\/products\/osg-1233605-spiral-point-tap-3-4-10-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
