Built from high speed steel with a coated finish, this bit measures 0.2854 inches (7.25 mm) in diameter with a 120-degree faceted drill point and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard drill chucks and CNC toolholders. The 2-flute spiral design with a 5xD flute-to-diameter ratio promotes efficient chip evacuation. The overall length is 78.00 mm (approximately 3.07 inches), making it well suited for close-quarter drilling where a jobber-length bit would be impractical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length profile is common in production environments, CNC drilling operations, and tool rooms where rigidity and minimal runout are priorities. The Series 1100 designation places it within OSG's high performance category. It ships as a single bit and is appropriate for use in both manual drill presses and CNC machining centers equipped with a compatible straight-shank toolholder sized for the 8.00 mm (approximately 0.315 inch) shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2854 inch (7.25 mm) diameter with a tolerance of +0 to -0.022 mm for consistent sizing\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted drill point with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design promotes chip evacuation in through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard chucks and CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe OSG 8595725 is rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. It fits standard drill chucks and straight-shank toolholders accepting an 8.00 mm shank. It falls within the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) drill bit size range of the Series 1100 product family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, tool-and-die technicians, or maintenance professionals familiar with drill press or CNC operation. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the bit from the toolholder. Verify shank seating depth and chuck torque according to the machine manufacturer's specifications before beginning a cut. Coolant-through is not supported on this bit; use external coolant or cutting fluid as required by the workpiece material and cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2854 inches (7.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 78.00 mm (approximately 3.07 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (approximately 1.34 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (approximately 0.315 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\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: 0.055 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: 8595725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733549187378,"sku":"8595725","price":81.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b87aa5e83878cd32b59f91ef0e83f266.jpg?v=1788756306","url":"https:\/\/voomisupply.com\/products\/osg-8595725-screw-machine-drill-bit-0-2854-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
