Built from high speed steel (HSS) with an oxide finish, this bit measures 0.3390 inches in diameter and carries a standard 118-degree split point angle suited for a wide range of production and maintenance drilling tasks. The overall length is 4.75 inches with a flute length of 3.4375 inches. The straight cylindrical shank seats securely in standard drill chucks without requiring a collet or adapter. Licensed trades and metalworking shops reach for this bit when drilling steel, cast iron, and similar workpiece materials in everyday service conditions.\u003c\/p\u003e\n\u003cp\u003eThis bit is appropriate for residential and commercial maintenance, fabrication, and general metalworking applications. The two-flute regular spiral design clears chips efficiently during through-hole and blind-hole drilling in steel and cast iron. The right-hand cutting direction pairs with standard forward-rotating drill presses, hand drills, and magnetic drills. The web-thinned, tapered web configuration reduces thrust force needed at entry, making it practical for hand-drill use as well as drill-press work where feed pressure control matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter R size: 0.3390 inches diameter for precise fractional-equivalent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suitable for steel and cast iron drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for surface hardness and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with standard drill presses, hand drills, and magnetic base drills accepting a straight shank of 0.3390 inches diameter.

Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before starting the drill. Do not exceed the rated speed for the bit diameter and workpiece material, and use cutting fluid when drilling ferrous metals to extend tool life and improve hole finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3390 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01189182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710779261234,"sku":"01189182","price":67.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/599365f6ca98b004b0ddb064dc10f363.jpg?v=1788470473","url":"https:\/\/voomisupply.com\/products\/value-collection-01189182-letter-r-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
