It is manufactured from high speed steel with an oxide coating that reduces friction and heat buildup during use. The bit measures 9.7 mm (0.3819 inches) in diameter with a 118-degree standard point angle and a right-hand spiral flute configuration. Overall length is 133 mm (5.24 inches) with a flute length of 87 mm (3.43 inches). The straight-cylindrical shank allows direct mounting in standard drill chucks. This bit is suited for shop technicians, maintenance mechanics, and trade professionals performing metal drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThe 47339 fits applications involving ferrous metals, including cast iron and steel stock commonly encountered in HVAC equipment fabrication, plumbing rough-in, electrical panel work, and general mechanical maintenance. The Series 150 designation places it in a general-purpose line built to DIN 338 specifications. The two-flute spiral design provides reliable chip evacuation in through-hole and blind-hole drilling scenarios at standard machine or handheld drill speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for reduced friction and extended tool life\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web configuration for easier starts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal in ferrous metals\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 specification for jobber-length twist drills\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0010 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.3819-inch straight-cylindrical shank.
