It measures 0.0508 inches (1.29 mm) in diameter with an overall length of 40.00 mm (approximately 1.57 inches) and a flute length of 8.00 mm (approximately 0.31 inches). The 140-degree faceted point angle and web-thinned, tapered web configuration reduce entry force and improve centering on hard materials. Constructed from high speed steel with a coated finish, this bit is built for high-performance applications where tool life and cut quality matter. It features a straight-cylindrical shank with a 3.00 mm (approximately 0.12 inches) shank diameter and a regular spiral flute with two flutes.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length designation means a shorter overall length compared to jobber-length bits, which improves rigidity and reduces deflection in close-tolerance drilling operations. It fits CNC machining centers, drill presses, and screw machines where compact tooling is required. The right-hand cut and spiral flute geometry support efficient chip evacuation. This bit is part of the OSG Series 1100 and is appropriate for machinists, toolroom technicians, and precision fabricators working in production or maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0508 inch (1.29 mm) diameter with a tight tolerance of +0 to -0.014 mm for close-tolerance work\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted drill point with web thinning for reduced entry force and improved centering\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body improves rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design promotes chip evacuation in steel and aluminum alloys\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard collets and drill chucks without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the straight-cylindrical shank firmly in the appropriate collet or drill chuck before operation. Ensure the spindle is fully stopped and the machine is de-energized before changing or inspecting tooling. Coolant-through is not supported on this bit, so external coolant or cutting fluid application should be used as required by the workpiece material and cutting conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0508 inches (1.29 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40.00 mm (approximately 1.57 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00 mm (approximately 0.31 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (approximately 0.12 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 8595129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733081227570,"sku":"8595129","price":38.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e96f90d04637deb9f5a7586f1adef40e.jpg?v=1788751176","url":"https:\/\/voomisupply.com\/products\/osg-8595129-screw-machine-drill-bit-0-0508-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
