Built from high speed steel with a coated finish, this bit features a 120-degree faceted drill point and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The straight-cylindrical shank measures 6.00 millimeters in diameter, and the overall length is 66.00 millimeters (approximately 2.60 inches). With two spiral flutes and a regular spiral type, the 8595416 evacuates chips efficiently during through-hole and blind-hole drilling operations. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length drill bit is optimized for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The shortened body of a screw machine length drill provides increased rigidity compared to jobber-length bits, making it a preferred choice for CNC machining centers, manual drill presses, and screw machine operations where chatter and deflection need to be minimized. The 0.1638-inch diameter falls within the 0.1500 to 0.2000 decimal inch size range of the OSG Series 1100 lineup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\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\u003e120-degree faceted drill point reduces walking and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting thrust and eases penetration into hard materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides greater rigidity and reduced deflection versus jobber-length drills\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with regular helix promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production drill within the OSG Series 1100 screw machine length family, suitable for standard drill chucks and collet holders accepting a 6.00-millimeter straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and maintenance technicians in drill presses, CNC machining centers, and screw machines. Power down and lock out the machine before inserting or removing the bit from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the machine specification before beginning a cut. Coolant-through is not supported on this bit; use external cutting fluid or mist coolant as appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1638 inches (4.16 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\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (approximately 2.60 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm (approximately 0.87 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (approximately 0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 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: 0.025 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: 8595416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751797981490,"sku":"8595416","price":49.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f7a09b2ec0dd3bfa899e41c13b41573.jpg?v=1788924305","url":"https:\/\/voomisupply.com\/products\/osg-8595416-screw-machine-drill-bit-0-1638-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
