It operates at an 82-degree included angle with a 41-degree centerline angle, making it well suited for standard flat-head fastener seat preparation. The 3\/16-inch straight cylindrical shank fits common drill chucks and collet holders. The bright, uncoated carbide construction provides rigidity and wear resistance across a range of workpiece materials. This tool is intended for right-hand cutting rotation and is supplied as a single end type without a pilot. Machinists, toolroom technicians, and fabricators install this countersink in manual drill presses, CNC machining centers, and hand-held power tools.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for use on alloy steel, cast iron, and glass-reinforced plastic. It is a compact, small-diameter tool appropriate for light-duty countersinking tasks where a 3\/16-inch head diameter is the required geometry. Typical applications include deburring and chamfering pre-drilled holes to accept flat-head screws and rivets in precision machined components. The single-flute geometry reduces chatter on harder materials and improves surface finish in the countersink seat.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n\u003cli\u003eSingle-flute design minimizes chatter on alloy steel and cast iron\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 3\/16 inches for broad chuck and collet compatibility\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for dry and light-coolant cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on alloy steel, cast iron, and glass-reinforced plastic workpieces.
