Hydraulic chucks are precision workholding devices used in machining applications to securely grip and hold cutting tools. These chucks utilize hydraulic pressure to clamp the tool shank, providing uniform and stable clamping force and minimizing runout. Their design offers improved accuracy, higher repeatability, and faster tool changes compared to other types of chucks. Hydraulic chucks are commonly used in milling, drilling, reaming, and tapping operations across a range of industries, from automotive and aerospace to medical and energy.
