Version:
The chip flutes are ground from solid up to size 31.5. Countersink point and circumference are relief ground and cut easily. This results in easy and chatter-free cutting for deep countersinking, as well as for deburring or countersinking.
Application:
For chatter-free countersinking and deburring.
Especially suitable for chamfering tapped holes and for countersinking in jig and tool making.
