BT-Style Flange Hydraulic Grip Holder for .500" Shank Diameter

Hydraulic clamping ensures high-torque gripping of the end mill. The complete circumference of the end mill is gripped, which eliminates the need for special seals. Precision balance is assured when using end mills without flats. The hydraulic chamber is completely enclosed, eliminating any possibility of contamination from coolant and dirt. The unique design of this holder provides excellent gripping over the long haul. Hydraulic End Mill Holders are for precision work (not for roughing) and for end mills with one cutting end. Retention knobs must be ordered separately for each holder. Stop screws are sold separately. Metric sizes available on application.

Benefits:

• Powerful hydraulic grip
• Radial repeatability of ±.00008" (.0020 mm)
• Vibration damping for chatter-free machining
• Full radial grip on tool’s diameter with greater gripping power than competitive holders
• Repetitive balance for high spindle speeds
• High gripping force provides a smooth and secure torque transmission to the cutting tool
• Ability to grip the end mill’s shank with or without flats - high-speed operations require end mills with no flats
• Standard through-the-spindle coolant
• Holders for metric tools are available on application
