Part of the HY-PRO NRT series, it is manufactured from cobalt high-speed steel and finished with a steam oxide coating. The modified bottoming chamfer — with 2 to 2.5 chamfered threads — allows threading close to the bottom of a blind hole. Overall length is 2.7165 inches (69.10 mm), with a thread length of 0.5906 inches (15.00 mm) and a maximum tapping depth of 1.1260 inches (28.60 mm). Machinists and toolroom professionals use this tap in production and maintenance environments where precise internal threads are required.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading blind holes in a range of workpiece materials, including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its thread forming — rather than cutting — action displaces material rather than producing chips, making it well suited for automated and CNC tapping operations where chip evacuation in a blind hole is a concern. The right-hand thread direction and 6H class of fit with D9 thread limit make it compatible with standard metric fastener assemblies across general manufacturing and industrial maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design eliminates chip evacuation problems in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt HSS construction provides heat and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves tap life\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2-2.5P) enables threading close to blind hole bottoms\u003c\/li\u003e\n\u003cli\u003e6H class of fit with D9 thread limit for standard metric fastener compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M8x1.25 metric coarse pitch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Use appropriate tapping fluid or cutting oil matched to the workpiece material. Secure the workpiece and use a calibrated torque-controlled tapping head or tap handle to avoid overloading the tap, particularly near the bottom of a blind hole. Do not reverse the tap under load without relieving torque first.\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 Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-2.5P\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt 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: 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\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: 0.057 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: 1410104501\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728469786930,"sku":"1410104501","price":31.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e9601a98fda9af356715c73b2088550.jpg?v=1788691715","url":"https:\/\/voomisupply.com\/products\/osg-1410104501-thread-forming-tap-m8x1-25-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
