Built from high-speed steel with a bright uncoated finish, it delivers reliable cutting performance across a range of metalworking and fabrication tasks. The tool features a 3\/16-inch body diameter, a 5\/64-inch drill point diameter, and a 90-degree included angle for the countersink profile. With a 118-degree drill point angle and right-hand cut direction, it suits standard drilling practice on drill presses and CNC setups alike.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for machine shops, maintenance facilities, and fabrication environments where countersinking fastener seats in metal workpieces is a routine task. The plain cutting edge style and non-tapered, non-aircraft body make it a straightforward general-purpose tool. Its long-length designation and 4-inch overall length give it reach for deeper setups or fixtures that require extended tool clearance. Licensed machinists, tool-and-die technicians, and maintenance mechanics commonly select this style of tool for production and repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill and countersink completes pilot drilling and seat forming in one pass\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across common ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003e90-degree included angle produces standard countersink profiles for flat-head fasteners\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suits general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with plain cutting edge style for conventional spindle operation\u003c\/li\u003e\n\u003cli\u003eLong-length design at 4 inches overall length provides extended reach in fixturing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose combination drill and countersink for use in standard drill press, lathe, or CNC machining center setups requiring a size 2, 3\/16-inch body diameter tool with a 90-degree countersink profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed in a compatible drill chuck or collet sized for a 3\/16-inch shank.
