Built from high speed steel with a bright polished finish, it delivers consistent performance in metal fabrication, sheet metal work, and general machining applications. The tool features a 5\/16 inch body diameter, a 1\/8 inch drill point diameter, and an 82-degree included angle, making it suited for standard flat-head fastener seating. At 2.125 inches overall length, it fits most standard drill presses and hand drills. Machinists, fabricators, and maintenance technicians working with ferrous and non-ferrous metals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is used in production and maintenance environments where a clean, properly countersunk pilot hole is required for flat-head screws and similar fasteners. Its compact overall length and double-end configuration make it a practical choice for bench work and light production runs. The right-hand cutting direction suits standard drill setups. It is commonly found in HVAC fabrication shops, electrical panel shops, plumbing fixture assembly, and general metalworking environments where countersinking is a routine task.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination drill and countersink completes pilot hole and countersink in one pass\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003eDouble-end style provides extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard drill presses and hand drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition for any drill press, CNC drill, or hand drill setup requiring a size 4 combination drill countersink with a 5\/16 inch body diameter and 82-degree included angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, fabricators, or maintenance technicians using standard drill chucks or collet holders. Secure the tool firmly in the chuck before operation and verify rotational runout before beginning a production run.
