Built from high-speed steel with a bright, uncoated finish, this tool features a 1\/8-inch body diameter, a 118-degree drill point angle, and a 90-degree included angle for countersinking. The double-end design and long-length construction make it a practical choice for machinists and tool-and-die professionals working in production or maintenance environments where efficiency and repeatability matter.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for use in metalworking applications where countersinking operations are required ahead of fastener seating. The plain cutting edge style and 90-degree included angle align with standard countersink requirements for common fastener types. With an overall length of 4 inches and a drill point diameter of 3\/64 inch, it fits standard drill chucks and is appropriate for light-duty to medium-duty countersinking tasks on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDouble-end design extends tool life by providing two usable cutting ends\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suits general-purpose drilling into metal\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle matches standard countersink requirements for common fasteners\u003c\/li\u003e\n  \u003cli\u003eLong-length tool at 4 inches overall for improved reach in deeper setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no additional coating variables that could affect finished hole dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard-stock combo drill countersink for metalworking applications requiring a Trade Size 1, 1\/8-inch body diameter tool with a 90-degree countersink angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this tool is performed by machinists or maintenance technicians using a standard drill press, milling machine, or CNC setup.
