It features a 1\/4 inch head diameter with a 60-degree included angle, making it suited for fastener seating and deburring operations in alloy tool steel and cast iron. The straight cylindrical shank measures 3\/16 inch in diameter for secure chuck engagement. An oxide coating reduces friction and extends tool life in production and job-shop environments. This tool is installed and used by machinists, tool-and-die workers, and maintenance technicians across manufacturing and fabrication settings.\u003c\/p\u003e\u003cp\u003eThe C46198 countersink is suited for countersinking operations in ferrous materials including alloy tool steel and cast iron. Its four-flute geometry provides smooth cutting action and reduced chatter compared to single-flute designs. The right-hand cutting direction is compatible with standard drill press and CNC machining center spindle rotation. Typical applications include preparing holes for flat-head fasteners, chamfering hole entries, and removing burrs from drilled holes in structural and precision components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch head diameter with a 60-degree included angle for standard fastener seat geometry\u003c\/li\u003e\n\u003cli\u003eFour-flute design for smooth, chatter-resistant cutting in ferrous metals\u003c\/li\u003e\n\u003cli\u003e3\/16 inch straight cylindrical shank for broad chuck compatibility\u003c\/li\u003e\n\u003cli\u003eOxide coating finish reduces friction and improves tool durability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut direction matches standard spindle rotation on drill presses and machining centers\u003c\/li\u003e\n\u003cli\u003eSingle-end construction; no pilot included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in alloy tool steel and cast iron.
