1.The single flut: cutting edges can better chip evacuation, the cutting edges is not easy to blunt,does not vibrate at high speeds for faster cutting than multiple flutes. These countersinks are often used for cutting smaller holes.
Two, Three, or Four Flutes:fine finish face,Each additional flute increases the tool life by distributing the cutting load over more edges. However, fewer flutes provide better chip clearance when machining stringy materials such as plastic.

2.Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe(v bit). They can also be used for chamfering and deburring.

3.90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.

4.Used in hardness 35 ° below the workpiece
