With a 100-degree included angle and a straight-cylindrical shank measuring 0.25 inches in diameter, this tool mounts directly into standard drill chucks and rotary tool holders. The right-hand cutting direction suits conventional drill press and handheld drill operation. Bright uncoated finish is standard. At 0.02 pounds, the tool is lightweight and easy to handle during repetitive countersinking tasks. Machinists, maintenance technicians, and fabricators working with fastener clearance holes will find this a practical single-end countersink for everyday bench use.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for general-purpose countersinking applications where a 100-degree included angle is required to match fastener head geometry. The 0.25-inch head diameter and matching shank diameter make it compatible with standard 1\/4-inch tool holders and drill chucks. Typical use cases include preparing holes for flat-head screws and bolts in light fabrication, assembly work, and field service environments. A single flute design provides a smooth cutting action at moderate feed rates and is appropriate for use in both manual and machine-driven setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-degree included angle matches common flat-head fastener specifications\u003c\/li\u003e\n  \u003cli\u003eSingle-flute geometry for smooth, chatter-reduced cutting action\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 0.25-inch shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose countersinking without specialized coating requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard drill press and handheld drill rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-inch straight-cylindrical tool holders, collets, and drill chucks used in drill press, CNC, and handheld drill applications requiring a 100-degree countersink geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the shank securely in the tool holder or chuck and verify runout before beginning operation. Power down and de-energize all equipment before changing or inspecting cutting tools. Use appropriate cutting speeds for the workpiece material and inspect the cutting edge for wear before each use.
