Built to wire size 15 (0.1800 inches), it features a 135-degree split-point angle with web thinning for fast penetration and reduced walking on entry. The straw oxide finish provides mild heat resistance and lubricity. Overall length is 3.375 inches, with a 2.1875-inch flute length and a straight shank diameter of 0.1800 inches. Licensed HVAC, plumbing, electrical, and mechanical trades all use cobalt jobber bits for drilling through structural steel, sheet metal, and hard alloys where high-speed steel alone falls short.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose drilling in steel, stainless, cast iron, and non-ferrous metals in both residential and light commercial applications. The R10CO-R15CO-R18CO series covers a wire-gauge size range of 0.1500 to 0.2000 inches decimal, making this bit appropriate wherever wire gauge 15 clearance or pilot holes are required. Typical applications include panel fabrication, equipment mounting, conduit entry drilling, and pipe flange work where hole accuracy and tool life matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance and extended tool life in steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and prevents bit walking\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish provides lubricity and mild corrosion protection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 12xD flute-to-diameter ratio handles chip evacuation effectively\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the R10CO-R15CO-R18CO series, covering wire-gauge drill sizes in the 0.1500 to 0.2000 inch decimal range.
