Built from cobalt high-speed steel with a TiCN coating, this tap handles demanding materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The M3x0.50 metric coarse thread profile and modified bottoming chamfer allow threading close to the bottom of blind holes. Overall length is 1.9291 inches (49.20 mm) with a thread length of 0.2441 inches (6.20 mm), making it suited for compact fastener applications in precision machining environments.\u003c\/p\u003e\u003cp\u003eThis tap is used in blind hole threading applications across general machining, toolroom, and production environments. The modified bottoming chamfer with 2 to 2.5 chamfered threads allows the tap to start a thread and work close to the bottom of a blind bore without requiring a separate bottoming tap operation. It is commonly applied in aerospace, automotive, and industrial fabrication shops where M3 metric fastener threads are required in tough ferrous and non-ferrous base materials. The Class of Fit 4H and D3 thread limit ensure consistent, accurate thread geometry on every pass.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing tap breakage risk in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life and reduces friction during forming\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 2.5P) allows threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003eClass of Fit 4H with D3 thread limit for precise metric thread geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M3x0.50 metric coarse profile\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 M3x0.50 metric coarse internal threads with a 4H class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a correctly sized forming tap drill hole — use the recommended forming tap drill chart for M3x0.50 to ensure proper material flow and thread form. Secure the workpiece and use a calibrated tap handle or CNC tapping cycle with the correct feed rate matching the 0.50 mm pitch. Apply cutting fluid appropriate for the workpiece material, particularly when working with stainless or alloy steel. Do not use this tap as a cutting tap — thread forming taps are not designed to remove material and will fail if used in cast iron or other brittle materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.50\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 to 2.5P\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\u003eOverall Length\u003c\/strong\u003e: 1.9291 inches (49.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.2441 inches (6.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.6299 inches (16.00 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\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\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: 0.026 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: 1410101608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732457685298,"sku":"1410101608","price":36.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4db06a184eb509833e3a8f45e68ca3d0_a34306ac-430e-41dd-b857-cd4c77b9c452.jpg?v=1788742981","url":"https:\/\/voomisupply.com\/products\/osg-1410101608-thread-forming-tap-m3x0-50-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
