Built from high-speed steel with a bright, uncoated finish, this tool features a 1\/2 inch body diameter, a 3\/16 inch drill point diameter, and a 118-degree drill point angle. The bell-style cutting edge and 60-degree included angle produce a clean countersink seat for fastener seating in metal fabrication, maintenance, and general machining work. It is installed and operated by machinists, toolroom technicians, and maintenance trades using standard drill presses or CNC machinery.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for countersinking and center-drilling applications in ferrous and non-ferrous materials. The right-hand cutting direction and double end type make it a practical general-purpose tool for job shops, production floors, and maintenance environments where clean countersink geometry and repeatable drill point starts are required. The 3-inch overall length fits standard tool holders and chucks without extended reach adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across common machining materials\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for standard center-drilling and countersinking\u003c\/li\u003e\n  \u003cli\u003eBell-style cutting edge with 60-degree included angle for accurate fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003eDouble end design extends usable tool life\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-style combination drill countersink for use in drill presses, lathes, and CNC machining centers that accept 1\/2 inch body diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and maintenance technicians using standard chucks or collet holders sized for 1\/2 inch body diameter tools. Ensure the machine spindle is fully stopped before loading or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.
