Built from high speed steel (HSS) with a bright, uncoated finish, this bit measures 5\/16 inch (0.3125 inches) in diameter with an overall length of 2-13\/16 inches and a flute length of 1-5\/8 inches. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. Machinists, tool-and-die professionals, and fabricators install this bit in drill presses, CNC machines, and screw machines where a shorter, more rigid bit is needed for accurate hole placement.\u003c\/p\u003e\u003cp\u003eThis screw machine length bit is suited for production drilling in tight setups where a jobber-length bit would introduce deflection or chatter. Its 2.5xD flute-to-diameter ratio and right-hand spiral flute geometry make it particularly effective in ferrous and non-ferrous metals. The primary workpiece material listed is titanium, indicating the bit is built to handle demanding, work-hardening materials in addition to general-purpose stock. It conforms to ANSI standards and carries a Series R40 designation from Precision Twist Drill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16 inch (0.3125 inches) diameter with screw machine length for rigid, low-deflection drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in metal cutting applications\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards; Series R40 designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length replacement bit compatible with standard straight-shank drill chucks on drill presses, screw machines, and CNC drilling equipment handling stock in the 0.3000 to 0.3500 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or tool operators. Secure the straight-cylindrical shank fully in a keyed or keyless chuck before operation and verify chuck runout is within acceptable tolerance before drilling titanium or other work-hardening materials. Always wear appropriate eye and face protection when operating drilling equipment. Inspect the cutting edges and web prior to each use; replace bits that show chipping, heat discoloration, or dulling to avoid workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/8 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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\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: R40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.083 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5998523\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699804864818,"sku":"5998523","price":45.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af237a1f867fe99455817684b9ecd10c.jpg?v=1788381249","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998523-5-16-in-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
