Built from high-speed steel with a bright, uncoated finish, this tool features a 5\/16 inch body diameter, a 1\/8 inch drill point diameter, and a 118-degree drill point angle paired with an 82-degree included countersink angle. At 4 inches overall length, it falls into the long-length category, making it well suited for reaching recessed workpieces. Machinists, tool-and-die workers, and metalworking professionals use this style of tool for deburring, chamfering, and seating flat- or oval-head fasteners flush with a workpiece surface.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is intended for countersinking operations in metalworking environments, including job shops, maintenance facilities, and production floors. The double-end style provides two usable cutting ends, extending tool life between replacements. The plain cutting edge style and uncoated high-speed steel construction make it compatible with a wide range of ferrous and non-ferrous materials at standard cutting speeds. It is sold and packaged individually, making it practical for both one-off maintenance tasks and production replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination drill and countersink completes drilling and chamfering in one operation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDouble-end design offers two cutting ends for extended tool service life\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suited for general-purpose metalworking applications\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head and oval-head fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003eLong-length designation at 4 inches OAL provides reach for deeper or obstructed setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use combo drill countersink for general metalworking and maintenance applications requiring a size 4, 5\/16 inch body diameter countersinking tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed in a compatible drill chuck or collet on a drill press, CNC machine, or hand drill.
