HOH Series Counter Balanced Power Chucks

This power chuck’s unique built-in counter balanced mechanism assures stabilized jaw force every time and provide maximum grippping force at high speeds.

Three-jaw wedge style power chucks are ideal for ultra high speed applications. They provide maximum gripping force at high speeds. Their unique built-in counter balanced mechanism assures stabilized jaw force every time. These deliver consistent accuracy and repetitive chucking. Counter balance allows for lower pressure gripping which is suitable for thin wall materials.
