Built from high-speed steel (HSS) with a bright finish, this tap pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping applications. The 2-flute geometry provides efficient chip evacuation and reduced torque requirements. At 1.75 inches overall length with a 7\/16 inch (0.441 inch) thread length and a 0.141 inch shank diameter, it fits standard tap holders and machine spindles. Thread limit is H3, indicating a tolerance class appropriate for standard UNC thread fits. Installed by machinists, maintenance technicians, and tool and die professionals.\u003c\/p\u003e\u003cp\u003eThis tap is designed for through-hole tapping in both manual and CNC machine tool applications. It is rated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The spiral point geometry makes it a practical choice for production environments where chip control in through holes is a priority. The right-hand thread direction is standard for conventional UNC fastener applications across industrial, HVAC equipment, electrical enclosure, and general mechanical assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread form, right-hand direction, H3 thread limit for standard tolerance fits\u003c\/li\u003e\n\u003cli\u003eSpiral point (gun tap) design pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n\u003cli\u003e2-flute configuration reduces torque and suits a variety of materials including hardened steel\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides good wear resistance across rated material applications\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement simplifies setup in standard tap holders\u003c\/li\u003e\n\u003cli\u003eCompact 1.75 inch overall length fits standard machine and hand tap holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping of 2-56 UNC threads.

Not intended for interrupted threads or coolant-through tooling setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a properly sized tap holder or floating holder to maintain alignment and reduce the risk of breakage, especially at the small 2-56 diameter. Always ensure the workpiece is securely fixtured before tapping. Apply a suitable cutting fluid for the material being tapped, even though this tap does not require coolant-through delivery. Follow standard shop safety practices and machine tool operating procedures when running in CNC or manual drill press applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.441 inches (7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\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: 0.007 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: 1210600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744024756530,"sku":"1210600","price":40.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d54235e55ee282f77bbc5fb45010d59.jpg?v=1788853113","url":"https:\/\/voomisupply.com\/products\/osg-1210600-spiral-point-tap-2-56-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
