It features a 0.0453 inch (1.15 mm) diameter, a 140-degree faceted drill point, and a two-flute spiral configuration ground from high speed steel. The shortened screw machine length body improves rigidity and reduces deflection in close-tolerance work. A web-thinned, tapered web design lowers thrust requirements and improves chip evacuation. This bit is suited for production environments and machine-tool use where consistent hole quality in metal stock is required.\u003c\/p\u003e\u003cp\u003eThe OSG 8595115 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its straight-cylindrical shank seats directly into standard drill chucks and collets on drill presses, CNC machining centers, and screw machines. The 5xD flute-to-diameter ratio and regular spiral flute geometry support chip removal in short-hole drilling cycles. This is a single-piece, individually packaged bit aimed at production machinists and tool crib operations requiring a high-performance small-diameter drill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0453 inch (1.15 mm) diameter with tolerance of +0 to -0.014 mm for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e140-degree faceted drill point reduces thrust and improves self-centering on hard metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance and aids chip flow\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral geometry supports efficient chip evacuation in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coating for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use in standard drill chucks and collets accepting a 3.00 mm straight-cylindrical shank across drill presses, CNC machining centers, and screw machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and tool room technicians in machine-tool setups. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight shank fully into the chuck or collet and verify runout before beginning a drilling cycle. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or hard alloys to manage heat and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0453 inches (1.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 39.00 mm (approximately 1.535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00 mm (approximately 0.276 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (approximately 0.118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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: 0.005 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: 8595115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753545433394,"sku":"8595115","price":35.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_87aa2b8f-8d58-41ce-a2ca-41bc19e0fadd.jpg?v=1788938069","url":"https:\/\/voomisupply.com\/products\/osg-8595115-screw-machine-drill-bit-0-0453-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
