Built to ANSI standards, this bit features a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The cylindrical shank measures 15\/64 inch (0.2344 inches) in diameter and the spiral flute geometry promotes efficient chip evacuation during through-hole and deep drilling operations. The bright\/uncoated finish makes it easy to inspect for wear. Machinists, tool-and-die workers, and maintenance technicians use this style of bit for general purpose drilling where taper length reach is required beyond what a jobber-length bit provides.\u003c\/p\u003e\n\u003cp\u003eThis taper length drill bit is suited for drilling aluminum, aluminum alloy, copper, magnesium, and magnesium alloy. The fast spiral flute design moves chips out of the cut quickly in these gummy, low-abrasion materials. The 6xD flute-length-to-diameter ratio gives extended reach into deeper workpieces while maintaining rigidity. It is appropriate for use in drill presses, CNC machining centers, and hand-held power drills in light industrial, HVAC fabrication, and plumbing rough-in applications where precise hole sizing in soft metal is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip reduces entry thrust and walking\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute geometry clears chips efficiently in aluminum, copper, and magnesium alloys\u003c\/li\u003e\n  \u003cli\u003eTaper length body (6xD flute ratio) provides extended reach beyond standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction delivers adequate hardness and toughness for general purpose drilling\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows easy visual inspection of cutting edges and flute condition\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general purpose taper length drill bit in the R51FS series, compatible with standard drill chucks accepting a 15\/64-inch (0.2344-inch) cylindrical shank.

Use appropriate cutting fluid or lubricant for copper and aluminum alloys to extend edge life and improve hole finish. Ensure the workpiece is clamped securely to prevent rotation on breakthrough. Inspect cutting edges and flute condition regularly and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 15\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2344 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\u003eOverall Length\u003c\/strong\u003e: 6.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with web thinning\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\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Copper, Magnesium, Magnesium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R51FS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5999009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720264122674,"sku":"5999009","price":29.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2b174d3bb8426732c23d2fa3ef705d6.jpg?v=1788562011","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999009-taper-length-drill-bit-15-64","provider":"Voomi Supply","version":"1.0","type":"link"}
