The bit measures 23\/64 inch (0.3594 inches) in diameter and features a 118-degree standard point angle with web thinning for reduced feed pressure at entry. The bright, uncoated finish is suited for applications where lubricity coatings are unnecessary or where regrinding frequency makes bare HSS the practical choice. At 6.75 inches overall length with a 4.25-inch spiral flute, this taper length format provides extra reach compared to a jobber-length bit without sacrificing rigidity.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in aluminum, aluminum alloy, copper, magnesium, and magnesium alloy. The right-hand spiral flute with fast spiral type promotes efficient chip evacuation in soft, gummy non-ferrous materials where chip packing is a common failure mode. The cylindrical shank (0.3594 inches) fits standard drill chucks and is compatible with both hand-held and machine setups including drill presses and CNC-style production fixtures. It meets ANSI standards for general-purpose drilling, making it a straightforward stock replacement for shops and field technicians running R51FS-series tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e23\/64 inch (0.3594 inches) diameter with matching cylindrical shank for true running in standard chucks\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for lower entry force\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute type improves chip clearance in aluminum, copper, and magnesium alloys\u003c\/li\u003e\n  \u003cli\u003e4.25-inch flute length (6xD ratio) provides extended reach vs. jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eBright uncoated HSS finish simplifies field regrinding and reduces tooling cost\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI general-purpose drill standards; Series R51FS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement for Series R51FS taper length drill bits in 23\/64 inch diameter.

Power down and de-energize the drilling equipment completely before changing bits or adjusting chuck tension. Use appropriate workholding to secure the workpiece and prevent rotation during drilling. Inspect the cutting edges and web condition before each use; a web-thinned point that chips or deforms should be reground or replaced before continuing service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 23\/64 inch (0.3594 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.25 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\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: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches\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 Length to Diameter Ratio\u003c\/strong\u003e: 6xD\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\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Copper, Magnesium, Magnesium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5999027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702486597938,"sku":"5999027","price":37.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d8dc0801a320876755e9ae19f7c1d07.jpg?v=1788411364","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999027-taper-length-drill-bit-23-64","provider":"Voomi Supply","version":"1.0","type":"link"}
