Built from high speed steel (HSS) with a coated finish, this bit features a 150-degree faceted drill point and a web-thinned, tapered web configuration that reduces entry force and improves centering accuracy. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 38.00 millimeters (approximately 1.5 inches). The two-flute spiral design promotes efficient chip evacuation during drilling. Machinists and tool-and-die professionals rely on this format for stub-length rigidity in tight clearance setups.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length (stub) format makes it a natural fit for CNC machining centers, drill presses, and manual lathes where shorter flute length and reduced deflection are priorities. The Series 1100 designation places this bit in OSG's high-performance line, making it appropriate for production environments where consistent hole quality and tool life matter. It is sold and packaged as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031 inch (1\/32 inch, Wire Size 68) drill diameter with a tolerance of +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e150-degree faceted drill point for accurate starts on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length format provides added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with 5xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a stub-length HSS drill bit for use in standard straight-shank drill chucks and collets accepting a 3.00 mm shank diameter, compatible with CNC machining centers, manual drill presses, and lathes configured for screw machine length tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and serviced by machinists and toolroom professionals. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation, and verify that runout is within acceptable tolerance for the application. Always power down and lock out the machine before changing tooling. Do not exceed the recommended speed and feed parameters for the workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.031 inches (1\/32 inch, Wire Size 68, 0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (approximately 1.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 8595079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749808701746,"sku":"8595079","price":47.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b78993bb26e88fd39515719bab020339.jpg?v=1788910732","url":"https:\/\/voomisupply.com\/products\/osg-8595079-screw-machine-drill-bit-0-031-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
