Built from high-speed steel (HSS) with a steam oxide coating, it is designed for general-purpose drilling in production and maintenance environments. The 118-degree standard point angle suits a broad range of materials and is compatible with conventional drill press and hand drill setups. Web-thinned construction reduces thrust and improves chip evacuation during through-hole drilling. Licensed trades and machining professionals reach for this bit when drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.\u003c\/p\u003e\u003cp\u003eThis bit fits standard jobber-length applications in metalworking, HVAC fabrication, plumbing rough-in, and electrical trade work where a straight-cylindrical shank and right-hand spiral flute are required. The R15 series designation places it within PRECISION TWIST DRILL's general-purpose HSS line. With a flute length of 3.4375 inches and an overall length of 4.75 inches, it handles drilling depths up to 3-7\/16 inches, making it appropriate for typical sheet metal, structural steel, and pipe flange work encountered in the field or shop.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter Q size, 0.3320-inch diameter with a straight-cylindrical shank of the same diameter for secure chuck grip\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry on a wide range of metals\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating provides light corrosion resistance and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design lowers thrust requirements and aids chip clearing\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral geometry supports consistent chip evacuation in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eANSI-standard dimensions ensure compatibility with standard jobber-length drill indexes and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length HSS drill bit suitable for use in any standard 3-jaw chuck or drill index accepting straight-cylindrical shanks.

Ensure the shank is fully seated and the chuck is tightened securely before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, particularly when drilling stainless steel or superalloys. Inspect the cutting edges for wear before each use and replace the bit if chipping or rounding is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 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: Steam 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3320 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\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4375 inches (3-7\/16 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\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\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722243014962,"sku":"5999304","price":17.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d1376067efa74e57cf29a3e46baef9d_7ff40f41-cd81-4a0d-8de9-0b3a09810683.jpg?v=1788588055","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999304-jobber-drill-bit-letter-q","provider":"Voomi Supply","version":"1.0","type":"link"}
