The Hydraulic Tool Holder reduces set up time due to its quick, easy and simple tool change. More clamping force compared to other collet chucks thus higher precision and better finishing of workpiece. Less vibration during routing operation. A hydraulic tool holder uses a reservoir of oil to equalize clamping pressure around the tool. When you place the tool in the holder and turn the screw inwards, it increases the oil pressure, causing an expansion of the sleeve to grip the tool shank.
