Built from high speed steel (HSS) with a coated finish, the bit measures 0.0673 inches (1.71 mm) in diameter and features a 140-degree faceted drill point for accurate, self-centering entry with reduced thrust force. The spiral flute geometry and web-thinned, tapered web configuration promote efficient chip evacuation during drilling. At an overall length of approximately 1.69 inches (43 mm), this screw machine length format offers added rigidity compared to jobber-length bits, making it well suited for close-tolerance work on drill presses, CNC machines, and automatic screw machines.\u003c\/p\u003e\n\u003cp\u003eThe 8595171 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its compact screw machine length and straight-cylindrical shank allow direct mounting in standard chucks and collets without special adapters. Typical applications include production drilling, precision hole-making in sheet metal and structural components, and repetitive-cycle operations on automated equipment. This bit is used by machinists, tool-and-die professionals, and metal fabricators working in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0673 inch (1.71 mm) diameter with a diameter tolerance of +0 to -0.014 mm for close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point angle reduces walking and improves entry accuracy on hard materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers cutting resistance and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish extends tool life in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (5xD flute-to-diameter ratio) provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2-flute configuration promotes chip clearance in deep holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Machinists should select appropriate cutting speed and feed rate for the specific workpiece material to avoid premature edge wear or bit breakage at this small diameter. Use cutting fluid or mist coolant where permitted by the machine setup, as coolant-through is not available on this bit. Inspect the cutting edge for wear regularly, as small-diameter HSS bits are sensitive to overloading and deflection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0673 inches (1.71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 43.00 mm (approximately 1.69 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11.00 mm (approximately 0.43 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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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 Materials\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8595171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748369826098,"sku":"8595171","price":38.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/920d470e312cd3578a1f25ecfdf076df.jpg?v=1788893016","url":"https:\/\/voomisupply.com\/products\/osg-8595171-screw-machine-drill-bit-0-0673-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
