• 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 endmill 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
CAUTION
A Stop Block is required.

• Results will vary depending on workpiece, cutting tool, machine model and other conditions
• The rigidity and concentricity are often affected by the projection length of a cutting tool, it is recommended to keep the projection as short as possible
