Built from high speed steel with a coated finish, it measures 0.043 inches (Wire Size 57) in diameter with an overall length of approximately 1.535 inches and a flute length of approximately 0.276 inches. The 140-degree faceted drill point and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. This bit is suited for machinists, tool-and-die workers, and fabricators who require tight-tolerance holes in small-diameter applications.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are shorter and more rigid than jobber-length bits, making them well suited for CNC machining centers, drill presses, and turret lathes where rigidity and accuracy are priorities. The 8595109 is rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Its compact geometry is especially practical for close-tolerance work in production environments where runout and deflection must be minimized. The 5xD flute-to-diameter ratio supports efficient chip clearing in shallow to moderate depth holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire Size 57 (0.043 inches) diameter with a tight tolerance of plus 0 to minus 0.0006 inches\u003c\/li\u003e\n\u003cli\u003e140-degree faceted point with web thinning reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish extends tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides greater rigidity than jobber-length bits, reducing deflection\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collets accepting a 3.00 mm (approximately 0.118 inches) straight-cylindrical shank.

Machinists should select appropriate cutting speeds and feeds for the workpiece material to avoid overheating the cutting edge. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or deep holes in steel. Inspect the drill point for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or misalignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 57\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0430 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.09 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 39.00 mm (approximately 1.535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 7.00 mm (approximately 0.276 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: plus 0 to minus 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: High Performance\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: 8595109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739889074482,"sku":"8595109","price":38.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50b1498e9703555ed0ef193fe6dd2495.jpg?v=1788820083","url":"https:\/\/voomisupply.com\/products\/osg-8595109-screw-machine-drill-bit-0-043-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
