Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it handles a broad range of workpiece materials with improved wear resistance and reduced friction. The tap cuts a 2-56 UNC thread profile with a plug chamfer, 2 flutes, and a right-hand thread direction. Class of fit is 2B with an H2 thread limit. Overall length is 1.75 inches, and thread length is 0.441 inches (7\/16 inches). This tap is used by machinists, tool-and-die makers, and maintenance technicians working on small-fastener threading operations.\u003c\/p\u003e\u003cp\u003eThe 1205605 is suited for threading through-holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Its spiral point geometry pushes chips forward ahead of the cutting zone, making it well-matched for production and repair work where through-hole access allows chip evacuation. The 2-56 UNC thread size is common in small instrument hardware, electronics enclosures, and precision mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread profile with plug chamfer for gradual thread entry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eH2 thread limit and 2B class of fit for standard tolerance threading\u003c\/li\u003e\n\u003cli\u003e2-flute spiral point design pushes chips forward in through-hole applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through required\u003c\/li\u003e\n\u003cli\u003eRated for aluminum, cast iron, and a wide range of carbon and hardened steels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in through-hole tapping operations requiring a 2-56 UNC thread form.

Always ensure the workpiece is securely fixtured and the pilot hole diameter is correct for a 2-56 UNC thread prior to tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Inspect the tap for wear or chipping before each use, and never force a tap that has stalled in the hole.\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\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 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\u003eCoolant Through\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: 0.009 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: 1205605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732396802354,"sku":"1205605","price":37.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b307976423ce78cd138cd86fd1281d46.jpg?v=1788742387","url":"https:\/\/voomisupply.com\/products\/osg-1205605-spiral-point-tap-2-56-unc-tin-coated-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
