Countersink, 82 °, 1 1/4", High Speed Steel, Bright (Uncoated)
High-speed steel countersinks provide good wear resistance in a wide range of countersinking applications. General purpose 3-flute countersinks are the most commonly used type of countersink. They expand the top of an existing hole in a range of materials to ensure screws install flush with the surface of the workpiece. Three-flute countersinks typically provide better chip clearance and perform better when machining stringy materials than countersinks with more flutes.
