Ground from high speed steel with a coated finish, this bit measures 3\/64 inch (0.0500 inch decimal) in diameter and features a 140-degree faceted drill point for improved centering and reduced thrust on entry. The stub-length body keeps the bit rigid, minimizing deflection in short-hole operations. Web thinning reduces cutting resistance, and the 2-flute spiral configuration evacuates chips efficiently. Machinists, tool and die technicians, and maintenance mechanics use this bit in drill presses, CNC machines, and handheld power tools.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine (stub) length format is a common choice in production environments where rigidity matters more than reach, such as tapping operations, jig work, and close-tolerance hole placement on sheet metal, structural steel, and cast aluminum components. The straight cylindrical shank fits standard Jacobs-style chucks and collet systems with a 3.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/64 inch (1.27 mm) diameter with a tolerance of +0 to -0.014 mm for consistent hole size\u003c\/li\u003e\n\u003cli\u003e140-degree faceted point for self-centering entry and reduced walking on hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces feed force and heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes efficient chip evacuation in blind and through holes\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides maximum rigidity and minimal deflection in short-reach drilling\u003c\/li\u003e\n\u003cli\u003eCoated high speed steel construction suited for steel, stainless steel, and aluminum alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine drill bit replacement for use in standard Jacobs chucks, collet holders, and CNC tooling setups that accept straight cylindrical shanks in the 3.00 mm range.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always match spindle speed and feed rate to the workpiece material and hole depth. Inspect the cutting edges for wear or chipping before each use and replace the bit when point geometry degrades to avoid oversized or out-of-tolerance holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 1.27 mm\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 Length\u003c\/strong\u003e: 8.00 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\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 Length Type\u003c\/strong\u003e: Screw Machine\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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\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: 0.01 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: 8595127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754855956786,"sku":"8595127","price":38.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7d35607e59fa2aeb5e65f8c77498871.jpg?v=1788949260","url":"https:\/\/voomisupply.com\/products\/osg-8595127-screw-machine-drill-bit-3-64-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
