BT40 Hydraulic Chucks
Hydraulic Chucks are NOT intended for roughing applications. Shrink Fit Holders or End Mill Holders are best for roughing applications.
Intended Use: All Hydraulic Holders are recommended for FINISHING applications only. Hydraulic Chucks are ideal tool holders for machining processes that require high accuracy and fine finishes because of their excellent runout, dampening properties and balance.
How to Use: Simply place the tool in the holder and turn the piston screw inwards until the screw comes to a DEAD STOP, no torque value to measure.
Use our optional sleeves to reduce bore size and hold many different size shanks.
Other Facts: The clamping screw pushes an internal piston that increases the oil pressure, causing an internal oil bladder to expand and shrink the tool holder bore.
