Built from solid carbide with a coated finish, this bit measures 5.20 mm (0.2047 inches) in diameter and features a 140-degree drill point angle optimized for reduced thrust and self-centering on hard materials. The two-flute spiral design with R-thinned web and tapered web configuration improves chip evacuation and cutting efficiency. At 82.00 mm (3.23 inches) overall length with a 26.00 mm (1.02 inches) flute length, it fits standard screw machine length setups. Coolant-through capability makes it suitable for production environments where heat management is critical. Licensed machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. The screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection in CNC machining centers, drill presses, and automatic screw machines. It is suited for both short-run toolroom work and higher-volume production runs where consistent hole tolerance and tool life matter. The 3xD flute-to-diameter ratio supports drilling to moderate depths without packing chips.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e140-degree split point angle reduces walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels fluid directly to the cutting edge for heat control in production drilling\u003c\/li\u003e\n\u003cli\u003eR-thinned web with tapered configuration improves chip flow and reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with 6.00 mm (0.236 inches) diameter fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eCoated finish extends tool life in steel, cast iron, and titanium alloy applications\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.

Secure the shank fully in the collet or drill chuck before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to side loading. Always engage coolant flow before the bit contacts the workpiece when using the through-coolant feature. Do not use this bit in hammer or impact-style drilling applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2047 inches (5.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82.00 mm (3.23 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26.00 mm (1.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.236 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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 Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\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\u003eSeries\u003c\/strong\u003e: 6500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.25 inches L x 0.45 inches W x 0.35 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 8690520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729532092722,"sku":"8690520","price":172.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b46ad03ea5170bff9de3e121ee42436_f5676d11-04f8-4448-8043-d9ab476971f8.jpg?v=1788705789","url":"https:\/\/voomisupply.com\/products\/osg-8690520-screw-machine-drill-bit-0-2047-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
