Bulk orders will be discounted, please contact us.

High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. Six-flute countersinks provide fast material removal and leave a smooth finish as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They remove more material with each revolution and typically provide more wear resistance than countersinks with fewer flutes.
