Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life and heat resistance in hard materials. The 140-degree notched point reduces walking at entry and improves centering without a pilot hole. At 2.5 inches overall length with a 3\/16-inch straight cylindrical shank, this bit fits standard drill chucks and CNC toolholders. The web-thinned, parallel web configuration reduces thrust load and aids chip evacuation during through-hole operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in ferrous metals, stainless steel, cast iron, and high-temperature alloys where standard high-speed steel bits fall short. The AlTiN coating makes it a strong choice in dry cutting or minimal-lubricant environments where heat buildup is a concern. It is commonly used by machinists, tool and die tradespeople, and precision sheet metal workers operating CNC drill presses, machining centers, or hand-held pneumatic drills. The 4xD flute-to-diameter ratio and 0.75-inch maximum drilling depth make it best suited for shallow to moderate hole depths in hard or abrasive workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides heat and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree notched point improves self-centering and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers cutting resistance and aids chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance jobber length drill bit for use in standard 3\/16-inch compatible drill chucks, collet systems, and CNC spindles that accept straight cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or trade professionals.
