It features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. A titanium nitride (TiN) coating increases surface hardness and extends tool life in high-cycle production environments. The straight cylindrical shank measures 0.3320 inches in diameter and fits standard drill chucks. With an overall length of 4.75 inches and a flute length of 3.4375 inches, this drill is well suited for general-purpose hole-making in both manual and machine-fed applications. Installation is typically performed by machinists, maintenance mechanics, and fabricators.\u003c\/p\u003e\u003cp\u003eThe C66045 is a general-purpose drill appropriate for job shop, maintenance, and light production use. It fits drilling operations on alloy steel, carbon steel, cast iron, aluminum, and non-ferrous metals where a cobalt substrate and TiN coating are needed to manage heat and abrasion. The right-hand spiral flute and tapered web configuration promote efficient chip evacuation. It conforms to ANSI specifications and belongs to CLE-LINE Series 1501-TT. This bit is suited for use in drill presses, lathes, and hand-held power drills with a compatible chuck capacity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel substrate resists heat buildup when drilling hard ferrous materials\u003c\/li\u003e\n\u003cli\u003eTiN coating improves surface hardness and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eTapered web with web thinning lowers cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes promote chip evacuation from the hole\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.3320 inches diameter fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill for use in standard drill chucks accepting a 0.3320-inch straight shank, conforming to ANSI specification designation for Letter Q sizing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, fabricators, and maintenance mechanics using drill presses, CNC drilling machines, or hand-held power drills. Secure the shank fully in the chuck before operation and verify chuck capacity covers the 0.3320-inch shank diameter. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling hard or thick stock to manage heat.
