INTRODUCTION
TOOLING SYSTEMS
Power Chucks
When using this tool, only a small tightening
torque compresses the frontal nose, providing an 3 2 1
extremely high gripping force. It is designed for
roughing and finishing applications in milling where
high torque transmission, maximum accuracy,
compactness and easy operation are required.
Features 10
• The clamping nut is not threaded (as in ER collet chucks)
• Designed for direct chucking of the tool shank –
no need for intermediate collet for maximum gripping force
• Sealed nut construction
• No axial drawback of the tool shank 11 9 8 5 4 6 7
