It measures 7.00 mm (0.2756 inches) in diameter with an overall length of 78.00 mm and a flute length of 34.00 mm. Built from coated high speed steel, it features a two-flute regular spiral configuration, a 120-degree faceted drill point, and a straight-cylindrical shank with a web-thinned, tapered web. The shorter body length of screw machine drills provides added rigidity and is commonly specified for drill press, CNC, and turret lathe operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand cutting in a range of ferrous and non-ferrous materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The stub-length design reduces deflection and runout when drilling in production environments. It fits into standard straight-shank toolholders and collet chucks, making it a practical choice for machine shops, maintenance technicians, and fabricators running high-cycle drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7.00 mm (0.2756 inches) diameter with a tolerance of +0 to -0.022 mm for precise fit\u003c\/li\u003e\n  \u003cli\u003eCoated high speed steel construction rated for high-performance applications\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted drill point with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body for improved rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Part of the OSG Series 1100 line, covering the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) diameter range.

Ensure the spindle is fully stopped and the machine is de-energized before loading or changing the bit. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always match spindle speed and feed rate to the workpiece material and consult the machine manufacturer guidelines; this drill does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 78.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel, Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 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: 61570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730740805938,"sku":"61570","price":71.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e9e6c3134312ccb8a98f37e640280f0.jpg?v=1788722036","url":"https:\/\/voomisupply.com\/products\/osg-61570-screw-machine-drill-bit-7mm-hss-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
