Abstract
A tool holder for a minimum quantity lubrication (MQL) device includes a tool holder body, a mixing chamber, a gas passageway, and an oil passageway. The tool holder body is configured for rotation about an axis. The tool holder body has a proximal end configured to be coupled to a spindle of the MQL device and a distal end configured to support a cutting tool for rotation about the axis. The mixing chamber is disposed within the tool holder body. The gas passageway is within the tool holder body and in fluid communication with the mixing chamber. The oil passageway is within the tool holder body and in fluid communication with the mixing chamber. The oil passageway is separate from the gas passageway and configured to receive a liquid lubricant from an oil conduit of the spindle.
