Manufactured from high-speed steel with a bright finish, this tap features a 3-flute spiral point geometry that drives chips forward ahead of the cutting zone, making it well suited for through-hole tapping operations. The thread size is M12x1.50 metric fine with a D6 thread limit, providing controlled tolerance for standard metric fine threaded assemblies. Overall length is 85.7 millimeters with a thread length of 1-21\/32 inches (23.9 millimeters). Licensed machinists, tool-and-die makers, and maintenance technicians install this tap in manual tap holders or CNC rigid tapping setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general metalworking and machining applications where M12x1.50 metric fine threads are required. It is appropriate for both production and maintenance environments. Listed material applications include aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer style — typically 3 to 5 threads of chamfer — allows the tap to start easily and is the most common choice for through-hole applications. Coolant-through capability is not present on this tap, so flood or brush-applied cutting fluid should be used during tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM12x1.50 metric fine thread form with D6 thread limit for controlled tolerance\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral point geometry pushes chips forward — optimized for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for easy starting in standard through-hole applications\u003c\/li\u003e\n  \u003cli\u003eBright (uncoated) finish — no coating buildup affecting thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, non-coolant-through design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders, T-handle wrenches, and CNC rigid tapping chucks that accept a 0.3670-inch (9.3218 millimeter) shank diameter with an 11.1125 millimeter square drive.

Always secure the workpiece fully before beginning the tapping operation and use an appropriate cutting fluid for the material being tapped. Inspect the tap and tap holder for runout before use, and never force a tap that has stalled — back it off to clear chips before continuing. Follow applicable shop safety standards and machine manufacturer guidelines when operating in CNC or power-feed tapping modes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (uncoated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 85.7 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches (23.9 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3670 inches (9.3218 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 11.1125 millimeters\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: 0.114 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1982900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752937881906,"sku":"1982900","price":59.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8622fe14ead3791ce91afd209b907a9.jpg?v=1788931302","url":"https:\/\/voomisupply.com\/products\/osg-1982900-spiral-point-tap-m12x1-50-metric-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
