The spiral point geometry pushes chips forward ahead of the cutting action, making it well suited for through-hole tapping applications where chip evacuation matters. Built from high-speed steel with a bright uncoated finish, this tap delivers reliable performance in general-purpose machine shop and maintenance environments. It features a plug chamfer for gradual thread engagement, 2 flutes, an H2 thread limit for close tolerance fits, and an overall length of 1-15\/16 inches with a thread length of 5\/8 inches. Licensed machinists, toolroom technicians, and maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in production and maintenance tapping operations where a 5-40 UNC thread form is required for helical insert installation. The STI designation means it cuts an oversized thread profile specifically sized to accept a coil-type screw thread insert, restoring or reinforcing threaded holes in aluminum, cast iron, steel, and similar materials. It is appropriate for both manual and machine tapping setups in light manufacturing, MRO, and toolroom settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward for efficient through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eSTI thread form cuts oversized profile for coil-type screw thread insert installation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability in general-purpose tapping applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with H2 thread limit for consistent, close-tolerance thread fits\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1-15\/16 inches accommodates restricted-access tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style production tap for use in applications requiring a 5-40 UNC STI thread profile sized for standard coil-type screw thread insert installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping operations should be performed by a qualified machinist or toolroom technician using a properly aligned tap handle, tapping head, or CNC machine with rigid or floating tap holder. Apply an appropriate cutting fluid for the workpiece material before and during tapping to reduce heat and tool wear. Secure the workpiece firmly before starting the tap to prevent misalignment and thread damage. Never reverse a tap under power without confirming the setup allows for proper chip clearance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches (2.13 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/8 inches (0.389 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7005000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742073061682,"sku":"7005000","price":41.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b77af604d074eec8744dd1c49c4d1a7.jpg?v=1788835223","url":"https:\/\/voomisupply.com\/products\/osg-7005000-spiral-point-sti-tap-5-40-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
