With a 0.0571-inch (1.45 mm) diameter, a 140-degree four-facet point, and a high speed steel construction, this bit delivers precise, clean entry holes in a compact stub-length format. The two-flute spiral design with web thinning reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 mm (approximately 0.118 inches) in diameter, making it compatible with standard drill chucks and collet systems. Machinists and tool-and-die professionals working on small-diameter bore requirements will find this a reliable production option.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length format — shorter than a jobber bit — increases rigidity and reduces deflection, making it well suited for CNC machining centers, drill presses, and manual turret lathes where stub-length tooling is preferred. The 5xD flute-to-diameter ratio supports consistent chip clearance across the full drilling depth. It is appropriate for both production floor use and precision repair work where small-diameter accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0571-inch (1.45 mm) diameter with tolerance of +0 to -0.014 mm for precision fitment\u003c\/li\u003e\n  \u003cli\u003e140-degree four-facet point reduces walking and improves entry accuracy on hard materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers cutting thrust on small-diameter bores\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length increases rigidity and minimizes deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with coated high speed steel for extended tool life in steel and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting a 3.00 mm straight-cylindrical shank.

Secure the workpiece firmly to prevent movement during drilling. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before starting the cut. Inspect the cutting edges for wear or chipping before each use, as small-diameter bits are susceptible to breakage if run at incorrect parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0571 inches (1.45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 41.00 mm (approximately 1.614 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm (approximately 0.354 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\u003ePoint Type\u003c\/strong\u003e: Four Facet\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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\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\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 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: 859514511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728180347186,"sku":"859514511","price":37.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/350a0d04cce349ff583d5999b4dfae6f.jpg?v=1788689070","url":"https:\/\/voomisupply.com\/products\/osg-859514511-screw-machine-drill-bit-0-0571-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
