Power Chucks

With this tool, only a small tightening torque compresses
the frontal nose, providing an extremely high gripping 3 2 1
force. It is designed for roughing and finishing applications
in milling where high torque transmission, maximum
accuracy, compactness and easy operation are required.

Features
• The clamping nut is not threaded (as in ER collet chucks) 10
• 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 as chuck is tightened
• Thick wall construction to withstand greater side 11 9 8 5 4 6 7
