It features a plug chamfer style, 2-flute geometry, and is manufactured from high-speed steel (HSS) with a steam oxide coating. The oxide finish provides corrosion resistance and mild lubricity during the tapping operation. At 49.2 mm overall length with a thread length of 5\/8 inches (8.3 mm), this is a compact tap suited for small-diameter threading work. The D3 thread limit and 6H class of fit make it appropriate for standard metric thread tolerances used in general machining and fabrication.\u003c\/p\u003e\u003cp\u003eThis tap is commonly used in machine shops, maintenance and repair operations, and production environments where M3 metric threaded holes are required. The spiral point design pushes chips forward ahead of the tap, making it well suited for through-hole tapping on CNC machining centers, drill presses, and tapping machines. Material compatibility includes aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel, giving it broad utility across ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM3x0.50 metric coarse thread form with 6H class of fit and D3 thread limit\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a wide range of materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves corrosion resistance and reduces friction during use\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for standard starting in pre-drilled through holes\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through, no interrupted thread\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces requiring M3x0.50 metric coarse through-hole threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a machinist or qualified technician using a properly aligned tapping fixture, CNC spindle, or manual tap handle. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct minor diameter before tapping. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or damage before each use and replace if chipping or dullness is observed.\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\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 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: 49.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/8 inches (8.3 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.5814 mm (0.1410 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 4.7625 mm\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: 142\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: 1980101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739667956018,"sku":"1980101","price":33.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfc2f1de8c12fe8e842967ac1403d2bd.jpg?v=1788817538","url":"https:\/\/voomisupply.com\/products\/osg-1980101-spiral-point-tap-m3x0-50-metric-coarse-6h-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
