Manufactured from high speed steel with a steam oxide coating, it resists heat and reduces friction during cutting. The bit features a 135-degree split point for accurate self-centering and reduced walking on hard surfaces. With an overall length of 4.5 inches and a flute length of 3.1875 inches, it fits standard drill chucks and drill presses used in trade and industrial environments. Licensed HVAC technicians, pipefitters, electricians, and general metalworkers reach for this bit daily on the job.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The 5\/16-inch diameter and straight cylindrical shank make it compatible with standard three-jaw chucks on handheld drills, drill presses, and mill setups. The regular spiral flute geometry and tapered web configuration support chip evacuation and reduce heat buildup across a range of material hardnesses. It is designed for right-hand cutting and carries an ANSI standard designation along with NAS 907 specification compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering and reduced bit walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and extends tool life in metal drilling applications\u003c\/li\u003e\n  \u003cli\u003eTapered web with web thinning for improved chip clearance and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry with a 10xD flute-to-diameter ratio for deep hole drilling control\u003c\/li\u003e\n  \u003cli\u003eNAS 907 and ANSI compliant for use in specification-driven work environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style replacement or direct-use jobber length drill bit compatible with any standard three-jaw chuck accepting a 5\/16-inch straight cylindrical shank.

Secure the straight shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat. Inspect the cutting edges before each use and discard bits showing chipping or excessive wear to avoid workpiece damage or bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches (3-3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 5998020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722738925874,"sku":"5998020","price":16.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e54529b321c8d88e787e6c4f803d17c6_d0c3e361-f934-4076-b175-3ae8a03c1d20.jpg?v=1788595164","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998020-jobber-drill-bit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
