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.
+ Add to CartSolid carbide countersinks provide excellent wear resistance when machining the toughest materials, such as cast iron and stainless steel. Single-flute countersinks are suitable for use at high speeds. They leave clean edges on holes and have a high, positive rake that reduces vibration as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece.
+ Add to CartHigh-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.
