Built from high-speed steel with a titanium nitride coating, this tool is suited for metalworking, fabrication, and light machining applications where efficiency and precision matter. It carries a trade size of 4, a 5\/16-inch body diameter, and an 82-degree included angle for countersinking. The 118-degree drill point angle is standard for general-purpose drilling into ferrous and non-ferrous metals. At 2-1\/8 inches overall length, it is compact and fits standard drill chucks and CNC setups.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is used in metal fabrication shops, machine shops, and maintenance environments where fastener seat prep is required before screw installation. It is suited for countersinking 82-degree flat-head fasteners in steel, aluminum, and similar workpiece materials. The right-hand cut direction and plain cutting edge style make it compatible with conventional drill press, lathe, and hand-drill operations. This tool is not aircraft-style and is not intended for deep-hole or long-reach applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction with titanium nitride coating for improved surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle for standard flat-head fastener countersinking\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with plain cutting edge for conventional rotary tool use\u003c\/li\u003e\n  \u003cli\u003eDouble end type for extended tool life\u003c\/li\u003e\n  \u003cli\u003eCompact 2-1\/8-inch overall length for use in standard chucks and CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard trade size 4 combination drill countersink suitable for use with conventional drill presses, lathes, and hand-held drills accepting a 5\/16-inch body diameter tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists, tool and die workers, and fabricators using standard rotary equipment. Secure the tool firmly in the chuck or collet before operation and verify spindle speed is appropriate for the workpiece material.
