Unlike cutting taps, this tool displaces material to produce stronger, chip-free threads. It is specified for 8-32 UNC threads with a modified bottoming chamfer of 2 to 2.5 chamfered threads, making it well suited for blind hole applications where thread depth is critical. Built from cobalt high-speed steel with a steam oxide coating, the tap offers improved lubricity and wear resistance under demanding production conditions. Overall length is 2.125 inches with a shank diameter of 0.168 inches.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in blind hole threading operations across a range of ferrous and non-ferrous materials. It carries material application codes P and N, covering alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. It is suited for machine tapping in CNC machining centers, drill presses, and tapping machines where right-hand threads are required. The modified bottoming geometry allows the operator to form threads closer to the bottom of a blind hole compared to standard taper or plug chamfer taps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces chip-free 8-32 UNC internal threads by cold displacement\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 2.5 chamfered threads) maximizes thread depth in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides elevated heat resistance and tool life in tough alloys and stainless steel\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling during forming operations\u003c\/li\u003e\n\u003cli\u003eClass of fit 2B with thread limit H5 for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through feature required for standard tapping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces requiring 8-32 UNC right-hand threads to a class 2B fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a properly sized forming tap drill hole — consult published forming tap drill charts for 8-32 UNC, as the correct hole diameter differs from standard cut tap drill sizes. Secure the tap in a rigid holder or floating tap head to minimize axial misalignment. Apply an appropriate tapping fluid or cutting oil compatible with the workpiece material before and during operation. Ensure the machine spindle is fully stopped and the workpiece is clamped securely before tap changes or setup adjustments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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: H5\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: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: HY-PRO NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1400114501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748852465970,"sku":"1400114501","price":30.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b92431930aa5bb81472af1c6dd52ec09.jpg?v=1788899588","url":"https:\/\/voomisupply.com\/products\/osg-1400114501-thread-forming-tap-8-32-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
