The tool features a 5\/8 inch body diameter with a 1\/4 inch drill point diameter and a 60-degree included angle, making it suited for creating clean, accurate countersunk holes in metalworking and machining applications. At 3-1\/4 inches overall length with a 1\/4 inch point length, this double-end tool offers extended service life. Right-hand cutting direction and a plain cutting edge style provide consistent chip removal. Installed by machinists, tool-and-die workers, and CNC operators.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is used in precision machining environments where a countersink and pilot drill operation must be completed in a single tool pass. It is suited for production machining, job shop work, and metalworking applications requiring tight tolerances on countersunk fastener seats. The solid carbide construction makes it appropriate for harder workpiece materials where high-speed steel tooling would wear prematurely. Trade size 7 corresponds to the drill point geometry specified for this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-pass combo drill and countersink operation reduces setup time\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in harder materials\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard countersunk fastener geometry\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends\u003c\/li\u003e\n\u003cli\u003ePlain cutting edge style for smooth countersink finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use combo drill countersink for machining and metalworking setups requiring a trade size 7 solid carbide countersink tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC operators.
