Built from cobalt high-speed steel with a bright finish, this M8x1.25 metric coarse tap features a plug chamfer with 4 to 4.5 chamfered threads for reliable thread starts in through-hole applications. The overall length is 2.7165 inches (69.10 mm) with a thread length of 0.5906 inches (15.00 mm). It carries a 6H class of fit and D9 thread limit, meeting standard tolerance requirements for metric fastener threads. This tap is intended for use by machinists, tool-and-die makers, and maintenance professionals working with precision threaded holes.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading in a wide range of ferrous and non-ferrous materials. The cobalt construction and HY-PRO NRT series design make it applicable across alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces. It is a strong fit for production machining environments, job shops, and MRO applications where consistent M8x1.25 internal threads are required in tough materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for performance in hardened and stainless steel\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through design for standard tapping setups\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads for easy thread entry\u003c\/li\u003e\n\u003cli\u003e6H class of fit and D9 thread limit for standard metric tolerance compliance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M8x1.25 metric coarse pitch\u003c\/li\u003e\n\u003cli\u003eThrough-hole threading application with a tapping depth of 1.1260 inches (28.60 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring M8x1.25 metric coarse internal threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a standard tap wrench, tapping head, or CNC machine tool equipped for rigid tapping. Before tapping, ensure the pilot hole diameter is correctly sized for M8x1.25 thread forming operations, as forming taps require a larger pilot than cutting taps. Use appropriate tapping fluid or cutting oil compatible with the workpiece material to extend tool life and maintain thread quality. Do not reverse the tap aggressively in interrupted cuts, as cobalt tooling can be brittle under sudden lateral stress.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D9\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\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7165 inches (69.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5906 inches (15.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.1260 inches (28.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3180 inches (8.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2380 inches (6.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.056 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: 1410104700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729885987122,"sku":"1410104700","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9d45c4f786bcba9f5fbbf59a730a73.jpg?v=1788709719","url":"https:\/\/voomisupply.com\/products\/osg-1410104700-thread-forming-tap-m8x1-25-cobalt-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
