It produces a 2-56 UNC thread profile with a plug chamfer, which provides a gradual lead-in and is suited for most standard through-hole tapping operations. The tap is manufactured from Vanadium High Speed Steel (HSS-E) and finished with a nitride coating to reduce friction, resist wear, and extend tool life. With 2 flutes and an H2 thread limit, it holds tight dimensional tolerances consistent with a 2B class of fit. Overall length is 1.772 inches with a 7\/16-inch (0.437-inch) thread length and a 0.141-inch shank diameter.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading small-diameter through holes in aluminum and cast aluminum workpieces, where chip evacuation and thread quality are critical. The spiral point geometry pushes chips forward ahead of the tap, making it effective in production environments and CNC machining centers. It is a standard choice for machine shops, maintenance facilities, and manufacturing lines working in the 2-56 UNC thread range on light-metal components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread profile with plug chamfer for standard through-hole tapping\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n\u003cli\u003eVanadium High Speed Steel (HSS-E) construction for improved toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eNitride coating reduces friction and extends tool life in production use\u003c\/li\u003e\n\u003cli\u003eH2 thread limit holds tight tolerances for 2B class of fit requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 2-56 UNC through holes in aluminum and cast aluminum.

Ensure the tap is properly aligned with the drilled hole to prevent breakage on this small-diameter tool. Use appropriate cutting fluid for aluminum even when coolant-through is not required. Follow shop standard speeds and feeds for 2-56 taps in high-speed steel to avoid overloading the flutes.\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 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: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum\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: 0.01 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: 1101600103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729294164274,"sku":"1101600103","price":52.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9124fe54516d4d8b1696dc8da337231e.jpg?v=1788702540","url":"https:\/\/voomisupply.com\/products\/osg-1101600103-spiral-point-tap-2-56-unc-plug-nitride-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
