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. The 60-degree included angle and radius cutting edge style make it suited for creating clean, chamfered entry points in metal and similar materials. It is used primarily by machinists, tool and die workers, and general metalworking tradespeople operating drill presses, CNC machines, or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is appropriate for general metalworking and fabrication environments where a size 4 tool is specified. With an overall length of 2-1\/8 inches and a right-hand cut, it fits standard drill chucks and is well matched to production and maintenance drilling applications where countersinking and center drilling need to be completed efficiently in one pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in metal cutting applications\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for standard metalworking entry geometry\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle with radius cutting edge for clean countersink profiles\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eDouble end type extends usable tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard drill chucks and spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for metalworking operations requiring a size 4 combination drill countersink with a 5\/16-inch body diameter and right-hand cut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and used by machinists and metalworking tradespeople.
