Unlike cutting taps, thread forming taps displace material rather than remove chips, producing stronger threads with a smoother finish. This tap features a semi-bottoming chamfer, allowing it to thread close to the bottom of a blind hole. Built from cobalt high speed steel with a V-coating finish, it delivers extended tool life in demanding production and maintenance machining environments. Machinists and tool-and-die technicians are the primary users of this tap in shop, field, and manufacturing settings.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloys, and titanium. The semi-bottoming chamfer makes it appropriate for blind-hole applications where thread depth close to the bottom is required. With a thread length of 0.526 inches (15 mm), an overall length of 3.937 inches (100 mm), and a right-hand thread direction, this tap fits standard machine tapping setups and manual tap handles with the correct square drive size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger, work-hardened threads with no chip evacuation required\u003c\/li\u003e\n  \u003cli\u003eCobalt high speed steel construction for heat and wear resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSemi-bottoming chamfer for threading close to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eV-coating finish reduces friction and extends tool life across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit for precise tolerance control on 1\/4-20 UNC 2B Class of Fit threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping machines and tap wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in applications requiring 1\/4-20 UNC internal threads with a 2B Class of Fit.

Ensure the workpiece is securely fixtured and the correct tapping fluid or cutting oil is applied for the specific workpiece material before beginning the tapping operation. For machine tapping, verify spindle speed is appropriate for the workpiece material and tap size. Inspect the tap for wear or damage before each use and replace if thread quality deteriorates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\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: Semi-Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.526 inches (15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 32 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.207 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Aluminum, Cast Aluminum, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, Hardened Steel, High-Nickel Alloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16255\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.4 x 2.1 x 0.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.057 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: 1625514226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737080004914,"sku":"1625514226","price":135.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_acf9377f-68e5-4d98-826e-5c183c0dba0f.jpg?v=1788783993","url":"https:\/\/voomisupply.com\/products\/osg-1625514226-thread-forming-tap-1-4-20-unc-2b-h6","provider":"Voomi Supply","version":"1.0","type":"link"}
