Built from cobalt high-speed steel with a steam oxide coating, this tap displaces material rather than removing it, resulting in stronger thread forms and longer tool life in production environments. The modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes. At 1.813 inches overall length and a shank diameter of 0.141 inches, it is sized for small-diameter tapping applications in precision machining and metalworking operations. It is installed by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in a range of ferrous and non-ferrous materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The HY-PRO NRT series is engineered for cold-forming applications where thread integrity and hole surface finish are critical. It is commonly used in CNC tapping centers, turret lathes, and manual tapping setups where small metric threads are required in production or repair work. The 4H class of fit and D3 thread limit make it appropriate for standard metric tolerance requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting chips, producing stronger threads and eliminating chip evacuation concerns in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance for tougher workpiece materials including hardened steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves lubrication retention during the tapping operation\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4H class of fit with D3 thread limit meets standard metric tolerance specifications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement, compatible with standard tapping lubricants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring M2.5x0.45 metric coarse threads at a 4H class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by a qualified machinist or toolroom technician familiar with thread forming operations. Ensure the workpiece is securely fixtured and the correct tap drill size for a thread forming operation is used, as forming taps require a larger pilot hole than cutting taps for the same thread size. Apply appropriate tapping fluid or cutting oil before and during the operation. Do not exceed the recommended tapping depth of 0.551 inches to avoid bottoming out and tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5x0.45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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: 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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.813 inches (46.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.512 inches (12.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.551 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 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\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: 1410101001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743894569266,"sku":"1410101001","price":44.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9c22ffa28bdd1d08b914c950ae45bdb.jpg?v=1788851012","url":"https:\/\/voomisupply.com\/products\/osg-1410101001-thread-forming-tap-m2-5x0-45-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
