Breackage of MT 2 Arbor  


We have the MT -2 of Mabasic 450 broken as in attached photo. Please check and advice.


The reason why the top of the conus was broken, is that, it was not correct mounted in the machine. 


The force of the drilling will be transmitted on the both cones.

When the cones doesn´t fit, than the force is on the top. The top is only to disengagement the cones.

When you connect the arbor in the machine, smash it with a plastic hammer inside.
