• Wrench must be ordered separately. • The “Max” allowable spindle speed listed in the table is directly influenced by the rigidity of the machine and balance of the cutting tool. Therefore, the “Max” allowable speed may not always be achievable. • Tools w/ flats should not be clamped w/ Mega Double Power Chuck.
