Built from high-speed steel with a bright uncoated finish, this tool handles both operations without a tool change. It measures 5 inches in overall length with a 7\/16-inch body diameter, a 3\/16-inch drill point diameter, and a 3\/16-inch drill point length. The 118-degree drill point angle is paired with a 60-degree included countersink angle. Machined with a plain cutting edge and a double end configuration, it suits production and maintenance shops where accuracy and cycle time both matter.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for metalworking, fabrication, and maintenance applications where flathead fasteners require a properly countersunk seat. The long-length designation makes it practical for reaching recessed work areas or drilling through thicker stock. It is typically used in manual or CNC drill press setups by machinists and maintenance technicians working with ferrous and non-ferrous metals. Trade size 5 places it in the standard range for medium fastener prep work in general manufacturing and repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombo drill and countersink in one tool — eliminates separate drilling and countersinking steps\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle with 60-degree included countersink angle\u003c\/li\u003e\n\u003cli\u003ePlain cutting edge style for smooth, consistent material removal\u003c\/li\u003e\n\u003cli\u003eDouble end configuration extends tool life by providing two usable ends\u003c\/li\u003e\n\u003cli\u003eLong-length designation at 5 inches overall for reach into deep or recessed workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style combo drill countersink for use in manual drill presses, CNC machining centers, and hand-held drilling equipment compatible with trade size 5 tooling and 7\/16-inch body diameter holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists or maintenance technicians using appropriate drill chucks or collets rated for the 7\/16-inch body diameter. Secure the workpiece firmly before operation and confirm spindle speed is appropriate for the material being cut. Inspect cutting edges before each use and replace if chipping or wear is detected.
