It features a bottoming chamfer, 2 flutes, and a 2B class of fit, making it suitable for tapping close-tolerance threads in shallow or restricted-depth holes. Manufactured from high speed steel (HSS) with a steam oxide coating, the tap offers improved lubricity and moderate corrosion resistance during cutting operations. With an overall length of 1.75 inches and a thread length of 0.44 inches, this tap is sized for small-diameter precision work commonly found in machining and assembly environments.\u003c\/p\u003e\u003cp\u003eThe OSG 1205701 is suited for threading low-carbon steel, medium-carbon steel, high-carbon steel, cast iron, and non-ferrous metals. The spiral point geometry pushes chips forward ahead of the cutting action, making it effective in through-hole applications where chip evacuation is critical. It carries an H2 thread limit designation, indicating a tight tolerance range appropriate for precision threaded assemblies in general manufacturing, instrumentation, and light mechanical fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point flute geometry drives chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer allows threading closer to the bottom of a hole than standard or plug chamfer taps\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness across a range of workpiece materials including carbon steels and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling during the tapping process\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures close tolerance fit per 2B class of fit requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through feature required for typical light-duty applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in 2-56 UNC tapped features in low-carbon steel, medium-carbon steel, high-carbon steel, cast iron, and non-ferrous metal workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed and operated by machinists or tool and die professionals familiar with small-diameter tapping procedures. Always secure the workpiece and use a properly aligned tap holder or tapping head to prevent breakage of small-diameter taps. Apply an appropriate cutting fluid for the workpiece material before and during the tapping operation. Inspect the tap for wear or chipping before each use, as small-diameter HSS taps are susceptible to breakage under misalignment or excessive feed pressure.\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\u003eThreads per Inch\u003c\/strong\u003e: 56\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: Bottoming\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 (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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: 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0179 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 105B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1205701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740245688626,"sku":"1205701","price":46.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65398680501eed073eebed0f73ce970c_8849bad4-971d-4d10-b5bd-7602051e93a9.jpg?v=1788823726","url":"https:\/\/voomisupply.com\/products\/osg-1205701-spiral-point-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
