It is machined from high speed steel with a steam oxide coating that helps reduce friction and resist corrosion during extended use. The 118-degree standard point angle suits a wide range of workpiece materials, and the web-thinned tip reduces feed pressure for more controlled entry. With a 5\/8-inch diameter and a 7.125-inch overall length, this bit fits standard drill chucks and drill press setups. It is a right-hand cut, two-flute, spiral-flute design built for production and field use across metal fabrication, maintenance, and mechanical trade applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The Series R10 designation places it in a general-purpose jobber-length family suited to hand drilling, drill press, and CNC operations where a straight-cylindrical shank is required. Maximum drilling depth matches the flute length at 5.1875 inches. The straight-cylindrical shank diameter is 0.625 inches, which seats securely in standard three-jaw drill chucks. Coolant-through capability is not available on this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch (0.6250 inch) diameter, jobber-length with 7.125-inch overall length\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point with web-thinned tip for reduced feed force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with steam oxide coating for corrosion and friction resistance\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design with tapered web configuration\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank with no flats\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit for use in standard three-jaw drill chucks accepting a 5\/8-inch straight-cylindrical shank, conforming to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, maintenance mechanics, and trade professionals using standard drill chucks on hand drills, drill presses, or CNC spindles. Ensure the chuck is fully tightened and the workpiece is secured before starting a cut. Use appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to manage heat buildup and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if the point shows chipping or heat discoloration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5998686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700219904306,"sku":"5998686","price":53.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8285143b76113f15c5f987c3a55f96e2_32c69b87-9df9-41ee-b06b-ebfb20cf3755.jpg?v=1788387765","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998686-jobber-drill-bit-5-8-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
