Part of the HY-PRO NRT series, it produces M2x0.40 metric coarse internal threads without cutting, displacing material instead of removing chips. This reduces the risk of chip packing in blind holes and results in stronger thread forms. The tap is manufactured from cobalt high-speed steel for elevated heat resistance and is finished with a TiCN coating that extends tool life in demanding applications. At 1.75 inches overall length with a bottoming chamfer of 1 to 1.5 threads, it is suited for threading close to the bottom of a blind hole. Installation is performed by machinist toolmakers, CNC operators, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where M2x0.40 metric coarse internal threads are required in blind holes. Suitable material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The 4H class of fit and D3 thread limit make it appropriate for standard metric fastener assemblies requiring controlled thread tolerance. Right-hand thread direction is standard for conventional tapping operations on manual or CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt HSS construction provides superior heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life in abrasive and high-temperature applications\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads allows threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003e4H class of fit with D3 thread limit for consistent, controlled thread tolerances\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading applications requiring M2x0.40 metric coarse internal threads in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Use a cutting or forming fluid rated for the workpiece material before tapping. Ensure the pre-drilled hole diameter meets the manufacturer recommendation for thread forming taps, which differs from cutting tap drill charts. On CNC equipment, program synchronous tapping cycles to match spindle speed with feed rate to avoid tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2x0.40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 4H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\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 High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (44.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4331 inches (11.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.4760 inches (12.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches (3.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches (2.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Applications\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 1410100408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728204955954,"sku":"1410100408","price":44.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/404e710941fb38e61209198299fab96a.jpg?v=1788689491","url":"https:\/\/voomisupply.com\/products\/osg-1410100408-thread-forming-tap-m2x0-40-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
