Built from high-speed steel with a bright, uncoated finish, this double-end tool accepts a right-hand cutting direction and features a bell-style cutting edge with a 60-degree included angle. The drill point measures 0.25 inches in diameter and 0.25 inches in length, while the body diameter is 0.75 inches and the overall length is 3.5 inches. It is sized as a trade size 18 tool and is suited for machinists, tool-and-die workers, and fabricators working with metal in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is used in drilling and countersinking operations on a range of ferrous and non-ferrous metals. Primary and secondary workpiece materials include alloy tool steel, aluminum, carbon steel, and cast iron. The double-end design extends tool life by providing two usable ends. The bell-style cutting edge geometry is well suited for creating clean countersink seats for flat-head fasteners. Typical applications include metalworking, fabrication, and machine shop work where a pre-drilled pilot and countersink are required in one pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across steel, aluminum, and cast iron\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends to extend tool life\u003c\/li\u003e\n  \u003cli\u003eBell-style cutting edge with 60-degree included angle for clean countersink seats\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with 118-degree drill point angle for general-purpose metal cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard drill presses, lathes, and CNC setups\u003c\/li\u003e\n  \u003cli\u003eTrade size 18 with 0.25-inch drill point diameter for common fastener countersinking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on alloy tool steel, aluminum, carbon steel, and cast iron workpieces.
