Manufactured from high speed steel (HSS) with a bright\/uncoated finish, this bit measures 0.3390 inches in diameter — equivalent to letter size R — with a 118-degree standard point angle and a web-thinned, tapered web configuration. The right-hand spiral flute design provides efficient chip evacuation during through-hole and deep-hole drilling operations. With an overall length of 6.5 inches and a flute length of 4.125 inches, this Series R55 bit offers extended reach compared to jobber-length equivalents, making it well suited for applications where standard-length bits fall short.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in a broad range of industrial, maintenance, and fabrication settings. The 6xD flute-to-diameter ratio provides increased reach for drilling in deeper stock or in confined setups where a longer bit is required. It is compatible with standard drill chucks accepting a 0.3390-inch straight shank and is appropriate for use in drill presses, hand drills, and CNC drilling setups. The Series R55 taper length format is commonly specified in machine shops, fabrication facilities, and MRO environments where extended-reach drilling is a routine requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for easier starting and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — suitable for general purpose use and easy to resharpen\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 6xD flute-to-diameter ratio for extended reach drilling\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.3390 inches fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Secure the straight shank firmly in a properly sized drill chuck before operation, and verify chuck runout is within acceptable limits to avoid premature wear. Always match spindle speed to the workpiece material and bit diameter per standard cutting speed tables, and use appropriate cutting fluid when drilling ferrous or hard materials. Inspect the cutting edges before use and resharpen or replace if chipping or dulling is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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 (Regular)\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: R55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 6000319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51717843321138,"sku":"6000319","price":36.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cebc37e082657d95531a3b98e962614.jpg?v=1788546600","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000319-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
