Manufactured from powdered metal and finished with a TICN coating, it delivers extended tool life in applications involving alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. The modified bottoming chamfer allows threading closer to the bottom of a blind hole, while the 3-flute spiral design evacuates chips up and out of the hole during the cut. Overall length is 1.75 inches. This tap is used by machinists and precision tooling technicians working on small-diameter fastener applications in tight-tolerance components.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance machining environments where 2-56 UNC threads are required in hard or abrasion-resistant materials. The right-hand flute direction and 10-degree helix angle make it effective in both CNC tapping cycles and manual tapping operations on #2-sized clearance holes. The 2B class of fit is the standard commercial tolerance for most UNC threaded assemblies. Typical applications include electronics enclosures, instrument housings, and precision mechanical assemblies where small-diameter threads must be cut cleanly and consistently.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTICN coating for extended wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading close to blind hole floors\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design promotes upward chip evacuation during cutting\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction for improved hardness and toughness over standard HSS\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent 2B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute direction; compatible with standard tapping attachments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 2-56 UNC threads in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces.

Always ensure the spindle is stopped and the workpiece is fully secured before engaging the tap. Use an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat and extend tool life. Follow ANSI and shop-standard procedures for tap alignment to avoid tap breakage in small-diameter applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThreads per Inch\u003c\/strong\u003e: 56\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 10 degrees\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: TICN\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: 0.437 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\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 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: 313TI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 1305710108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755331748146,"sku":"1305710108","price":127.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/865f2fd453b055394b379cb6119947be.jpg?v=1788953778","url":"https:\/\/voomisupply.com\/products\/osg-1305710108-spiral-flute-tap-2-56-unc-ticn-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
