It carries an M2x0.40 Metric Coarse thread profile with a bottoming chamfer of 1 to 1.5 threads, making it suited for threading to near the bottom of shallow or close-tolerance blind holes. The tap is manufactured from cobalt high-speed steel and finished with a steam oxide coating that reduces friction and improves lubrication retention during the forming process. Overall length is 1.75 inches with a thread length of 0.4331 inches and a shank diameter of 0.1410 inches. It operates right-hand thread direction and holds a Class of Fit 4H with a D3 thread limit.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in production and maintenance applications requiring precise small-diameter metric threads in materials including alloy steel, carbon steel, die steel, hardened steel, aluminum, and stainless steel. The HY-PRO NRT series is designed for blind hole threading where chip evacuation is a concern, as the cold-forming method eliminates chips entirely. Typical applications include instrument components, small mechanical assemblies, and precision hardware where thread strength and consistency at minimum diameter are priorities. A licensed machinist or tool and die technician would commonly use this tap in a CNC machining center, drill press, or tapping head setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCold-forming design produces no chips, reducing the risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer of 1 to 1.5 threads allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat and wear resistance for harder work materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating supports lubrication retention and reduces galling during forming\u003c\/li\u003e\n\u003cli\u003eClass of Fit 4H with D3 thread limit for consistent, close-tolerance metric threads\u003c\/li\u003e\n\u003cli\u003eCoolant-through feature is not present; suitable for use with applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread forming tap for M2x0.40 Metric Coarse blind hole applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and that the pilot hole is drilled to the correct forming tap pilot diameter for M2x0.40 before tapping. Because thread forming displaces rather than cuts material, adequate lubrication or cutting fluid must be applied to prevent tap seizure and thread distortion. Do not use this tap in through-hole applications where the bottoming chamfer geometry would leave incomplete threads at entry.\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\u003eChamfer Type\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\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\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: Steam Oxide\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: 0.1100 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\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: 0.01 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: 1410100401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752507965746,"sku":"1410100401","price":44.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca448a96a5ba74c86fd75c5f79b1d0b7.jpg?v=1788928724","url":"https:\/\/voomisupply.com\/products\/osg-1410100401-thread-forming-tap-m2x0-40-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
