Built with a solid carbide cutting head and a steel shank, this tool delivers clean, accurate chamfers in harder workpiece materials where rigidity and wear resistance matter. The 1-1\/4 inch head diameter and 100-degree included angle (50-degree centerline angle) make it suitable for creating standard countersunk fastener seats. The 3\/4 inch straight-cylindrical shank fits standard toolholders and collet chucks. At approximately 0.1 pounds, the tool is compact and balanced for use in drill presses, machining centers, and CNC setups.\u003c\/p\u003e\n\u003cp\u003eThis countersink is intended for use in machine shop environments, tool rooms, and production settings where consistent countersink geometry is required. It is suited to ferrous and non-ferrous metals where a solid carbide cutting edge provides better performance than high-speed steel alternatives. Machinists, tool-and-die makers, and CNC operators are the primary installers and users of this tool. It is sold as a single unit with no pilot included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch head diameter for larger-diameter countersink applications\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle produces standard fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide cutting head for extended tool life and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design for smooth cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch straight-cylindrical steel shank for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use with standard machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit countersink for machining centers, drill presses, and CNC equipment accepting a 3\/4 inch straight-cylindrical shank.
