Built from high speed steel with a coated finish, this bit features a 120-degree faceted drill point, web-thinned tapered web, and a two-flute spiral configuration for efficient chip evacuation. The straight-cylindrical shank measures 8.00 mm in diameter, and the overall length comes in at approximately 2.95 inches (75 mm). At 0.2461 inches (6.25 mm) diameter, this bit falls in the Letter D size classification. It is engineered for right-hand cutting and carries a heavy-duty grade rating suited to demanding production and field use.\u003c\/p\u003e\u003cp\u003eThis screw machine drill bit is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length format — shorter than jobber length — provides added rigidity and improved hole accuracy in drill press, CNC, and turret lathe setups. The 5xD flute-to-diameter ratio supports deep drilling within the screw machine length class. The Series 1100 designation identifies it within the OSG catalog for standard heavy-duty stub-length drilling. Licensed machinists, tool and die professionals, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2461 inches (Letter D) diameter with a tolerance of +0 to -0.022 mm for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces cutting resistance at the chisel edge\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity than jobber-length equivalents\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes with regular spiral type for consistent chip removal in steel and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe OSG 8595625 is compatible with workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The straight-cylindrical shank fits standard drill chucks and collets accepting 8.00 mm shank diameters. It is designed for use in drill presses, CNC machining centers, and turret lathes requiring a screw machine length stub bit in the 0.2000 to 0.2500 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall this bit into a properly sized drill chuck or collet, ensuring the shank is fully seated and the chuck is tightened to manufacturer specification before operation. Power down all equipment completely before changing bits. Use appropriate cutting fluid or coolant on the workpiece material, especially when drilling stainless steel, to prevent work hardening and extend bit life. Follow all applicable machine guarding and PPE requirements per OSHA and shop safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2461 inches (6.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.95 inches (75.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.22 inches (31.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\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: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 8595625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731700121906,"sku":"8595625","price":77.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_cb357403-e173-4b06-b5c6-df23073ba885.jpg?v=1788734025","url":"https:\/\/voomisupply.com\/products\/osg-8595625-screw-machine-drill-bit-0-2461-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
