It features a 3\/4 inch head diameter with a 60-degree included angle (30-degree centerline angle) and six flutes for smooth, efficient material removal. The straight cylindrical shank measures 1\/2 inch in diameter, making it compatible with standard drill chucks and collet holders. The bright, uncoated finish is suitable for general-purpose countersinking applications. This tool is used by machinists, fabricators, and maintenance technicians working with drill presses, milling machines, and CNC equipment.\u003c\/p\u003e\n\u003cp\u003eThe SC2160048 countersink is suited for countersinking screw and fastener seats in metal workpieces in both shop and field environments. Its right-hand cutting direction aligns with standard spindle rotation, and the six-flute geometry reduces chatter and produces a cleaner seat finish compared to fewer-flute designs. It does not include a pilot, so center alignment relies on operator technique or a center-drilled starting hole. Typical applications include deburring, chamfering, and preparing holes for flat-head fasteners in steel and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch head diameter with 60-degree included angle for standard fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003eSix flutes for reduced chatter and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction for increased heat and wear resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight cylindrical shank for compatibility with common chuck sizes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut matches standard spindle rotation on drill presses and mills\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish; no pilot included; single-end design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in drill presses, milling machines, and hand-held drilling equipment accepting a 1\/2 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or trained fabricators. Secure the shank fully in the chuck or collet before operation and confirm the workpiece is firmly clamped. Power down and de-energize the machine before changing tooling.
