With an 8.86 mm diameter, a 140-degree R-thinned point, and an EgiAs coating, this bit delivers precise entry geometry and extended tool life when cutting through tough workpiece materials. The overall length of 101 mm and a flute length of 45 mm make it well suited for stub-length drilling where rigidity and accuracy are priorities. A 10 mm straight-cylindrical shank provides secure clamping in standard drill chucks or toolholders. Two spiral flutes with a regular helix evacuate chips efficiently, reducing heat buildup and maintaining bore quality across the full cut depth. This bit is intended for installation and use by machinists and tool-and-die professionals working on CNC and manual machine platforms.\u003c\/p\u003e\u003cp\u003eThe OSG 650034811 is built for drilling steel, alloy steel, cast iron, titanium, and titanium alloys in both production and job-shop environments. Its 3xD flute-to-diameter ratio suits short-hole drilling cycles on vertical machining centers, drill presses, and turret lathes. The coolant-through design supports internal coolant delivery when the toolholder and spindle supply is available, helping to flush chips and manage cutting temperatures at depth. The tapered web configuration with R-thinned point geometry reduces thrust force at drill entry, which is especially beneficial when machining harder alloys. This bit fits within the OSG Series 6500 product family.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous and titanium alloys\u003c\/li\u003e\n\u003cli\u003eEgiAs coating extends surface hardness and wear resistance for longer tool life\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point reduces entry thrust and improves self-centering accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with internal coolant delivery systems\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity in short-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit within the OSG Series 6500 line. Primary workpiece materials include steel, alloy steel, cast iron, titanium, and titanium alloy. Compatible with any toolholder accepting a 10 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the toolholder or chuck before tightening to manufacturer-specified clamping torque for the toolholder type in use. Verify coolant-through passages are clear if using internal coolant delivery. Do not exceed the recommended cutting parameters for the workpiece material and machine spindle rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.86 mm (0.3488 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101 mm (3.9764 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.0394 inches decimal shank OD as listed)\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: R-Thinned\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.185 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.15 inches (L) x 0.5 inches (W) x 0.45 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 650034811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731807076658,"sku":"650034811","price":304.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0415b3e4b641e2e6234d8816758de3b7.jpg?v=1788735149","url":"https:\/\/voomisupply.com\/products\/osg-650034811-screw-machine-drill-bit-8-86mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
