Built from high speed steel with a black oxide coating, it runs a standard 118-degree point angle and a right-hand spiral flute configuration. The bit measures 4.75 inches overall with a 3.4375-inch flute length and a straight cylindrical shank at 0.3390 inches in diameter. The black oxide finish reduces friction and provides light corrosion resistance during storage. Machinists, tool-and-die workers, and maintenance technicians use this bit for production and maintenance drilling in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. It fits standard drill chucks accepting a 0.3390-inch straight cylindrical shank. Typical applications include drilling clearance and tap holes in structural steel, machine components, and fabrication work. The regular spiral type and 2-flute geometry support efficient chip evacuation in through-hole and moderate-depth drilling operations up to 3.4375 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter R drill size — 0.3390 inches decimal equivalent\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in metal drilling\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and surface corrosion\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose use\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight cylindrical shank — fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard jobber drill bit for use in any drill press, CNC drilling setup, or hand drill accepting a 0.3390-inch straight cylindrical shank.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid when drilling stainless steel, cast iron, or titanium alloys to extend bit life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace if the point shows visible degradation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches (3-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches (4-3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4375 inches (3-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CD40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD40318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51728548299058,"sku":"CD40318","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6250d35b636306839ea17576e532072.jpg?v=1788693131","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd40318-jobber-drill-bit-letter-r-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
