AT Countersink & Deburring Tools

Alfa Tools produces countersink and deburring tools—precision-engineered cutting tools for creating countersunk recesses for flush-mount fasteners and removing sharp burrs from drilled, milled, or cut edges. Made from high-speed steel (HSS) with precision-ground cutting edges, these tools deliver smooth, clean countersinks for flathead screws and rivets while efficiently deburring holes and edges in metal, plastic, and composite materials. Available in standard 82° countersink angles, with multiple shank options—including Monolock 1/4" hex for quick-change setups—and a wide range of sizes to fit all common fasteners.
