Built from high-speed steel with a bright, uncoated finish, it features a plug chamfer style that suits through-hole and moderate-depth blind-hole tapping operations. Four flutes provide chip clearance and cutting stability at standard machine tapping feeds. The 6H class of fit delivers a standard metric tolerance suitable for most general-purpose fastener applications. This tap carries a D5 thread limit, indicating controlled oversize for use with standard taps and dies.\u003c\/p\u003e\u003cp\u003eThe OSG 1971000 is suited for production and maintenance tapping in machining, fabrication, and toolroom environments. Its straight flute geometry is best applied in shorter-chipping materials. Rated material applications include aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. It fits standard tap holders, collet chucks, and tapping heads used in CNC machining centers, drill presses, and manual tapping arms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM6x1.00 metric coarse thread form with 6H class of fit for standard tolerance fastener holes\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style for versatile use in through holes and moderate-depth blind holes\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute geometry for chip clearance in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eD5 thread limit for controlled oversize within standard tapping parameters\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish  -  no coating buildup to interfere with close-tolerance thread production\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces requiring M6x1.00 metric coarse internal threads to a 6H fit class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tool and die technician familiar with tapping operations. Power down and de-energize the machine before changing tooling. Ensure proper alignment between the tap axis and the drilled pilot hole to avoid tap breakage or thread distortion. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6x1.00\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: D5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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 Length\u003c\/strong\u003e: 1 inch (15.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches (6.477 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches (4.8514 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 3.00 mm\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 141\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.028 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: 1971000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741231776050,"sku":"1971000","price":24.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36913bae3083974666c5d707c2978223.jpg?v=1788830214","url":"https:\/\/voomisupply.com\/products\/osg-1971000-m6x1-00-straight-flute-tap-6h-hss-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
