It features a 2-56 UNC thread form with a plug chamfer, 2 flutes, and an H2 thread limit for consistent dimensional control. The powdered metal construction delivers higher wear resistance than standard high-speed steel, making it well suited for production threading in tough alloys. A steam oxide coating reduces friction and improves chip flow. This tap produces right-hand threads and is sized for the 2-56 UNC thread standard, commonly encountered in precision assembly and light mechanical applications.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for threading operations in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel. The plug chamfer distributes cutting load across several leading threads, making it a practical choice for through-hole applications. It fits standard tap holders used in machine tapping and CNC operations, as well as hand-tapping setups where fine-thread precision is required in small-diameter holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread form with plug chamfer for through-hole threading\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction for enhanced wear resistance in difficult materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures consistent 2B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, no coolant-through requirement\u003c\/li\u003e\n\u003cli\u003eCompact geometry suited for small-diameter precision threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel.

Ensure the workpiece is securely fixtured and the correct tap drill size for 2-56 UNC is used before tapping. Apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Avoid reversing direction mid-thread, as small-diameter taps are susceptible to breakage under torsional stress.\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\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\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 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: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 312\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: 1759001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737188991282,"sku":"1759001","price":77.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5626c276e66d5574417682d6799ce65f.jpg?v=1788785396","url":"https:\/\/voomisupply.com\/products\/osg-1759001-spiral-point-tap-2-56-unc-plug-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
