Abstract: A housing having a cylindrical upper portion for attachment to the quill of a vertical milling machine. The lower portion of the housing includes two concentric cones of funnel shape extending downward from the upper portion having a funnel opening at the bottom for passage of a cutting tool, and for use as a vacuum port for extraction of waste coolant and chips. The space between the two cones provides passage of air and coolant which is ejected at the bottom of the cones and directed to the cutting tool and work piece. The angle of air ejection depends on the angle of the cone. The housing upper portion has an air input connector for supplying the air to the space between the two concentric cones, and contains channels for directing coolant from a coolant input connection to a plurality of fluid lines configured between the cones to carry the fluid to the opening at the bottom of the cones for directing the coolant towards the cutting tool.
