Built to Series 6500 specifications, this bit features a 140-degree drill point angle, spiral flute geometry, and an R-thinned, tapered web configuration that improves chip evacuation and reduces thrust at entry. Coolant-through capability supports extended tool life in high-cycle production environments. The straight-cylindrical shank provides secure seating in standard drill chucks and collet holders. At 0.6252 inches (15.88 mm) in diameter, this bit is sized for precise bore work where dimensional tolerance is critical.\u003c\/p\u003e\u003cp\u003eThe OSG 650062511 is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys in machining centers, CNC drilling operations, and manual machine shop setups. The screw machine length format — shorter overall length than jobber bits — provides added rigidity and improved concentricity in short-reach drilling applications. The 3xD flute-to-diameter ratio and right-hand spiral flute pattern support controlled chip removal in both through-hole and blind-hole operations. This bit is typically used by machinists, tool-and-die technicians, and CNC operators working with ferrous and exotic materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high hardness and wear resistance in ferrous and exotic materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces breakthrough burring and improves centering on hard materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed production drilling and extended bit life\u003c\/li\u003e\n\u003cli\u003eR-thinned, tapered web reduces cutting resistance and lowers thrust force at entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length format increases rigidity compared to jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces.

Ensure the chuck or collet is properly torqued to the manufacturer specification for the holding device in use. Coolant lines should be confirmed clear and flowing before beginning high-speed production runs with coolant-through tooling. Follow applicable shop safety standards and machine tool manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.6252 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 15.88 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eFlute Length\u003c\/strong\u003e: 80.00 mm (approx. 3.15 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 145.00 mm (approx. 5.71 inches)\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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 -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron, Titanium, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.95 x 0.85 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.685 pounds\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: 650062511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744538591538,"sku":"650062511","price":634.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_d9beb11e-1ba1-47cd-94fe-a1b37da90ce9.jpg?v=1788857759","url":"https:\/\/voomisupply.com\/products\/osg-650062511-screw-machine-drill-bit-0-6252-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
