A Stop Block is required. ! CAUTION

• NEW BABY COLLET, nut and 2 tightening wrenches are included • The allowable torque is a calculated value of the drive system, and not the actual torque in cutting • The maximum diameter when using an end mill is Ø8mm (GTG5, GTG6) and Ø12 (GTG4) • A Stop Block is required when mounting on machines • For continuous rotation of over 30 minutes, the spindle speed should be set within 80% of the maximum speed
