Original vintage Monroe Chemical Co. Mister Cool-Tool mist unit from long-term dealer inventory.
The Mister Cool-Tool is designed to provide an adjustable coolant/lubricant mist at the cutting area of machine tools such as mills, lathes, drill presses and similar equipment. The magnetic base allows the unit to be positioned on a suitable metal machine surface, while the flexible metal nozzle assembly directs the mist to the work area.
Features:
Important Model Identification Note:
The original factory box is marked Model 20-S, while the mister body itself carries a Model 12-S label. All four boxed examples from this original dealer inventory have this same configuration, including the longer flexible nozzle assembly. Original Monroe literature identifies the 20-S as the long-tube single-nozzle model. Please review the photos showing both markings and the original literature.
This unit appears unused and comes from long-term dealer inventory. It has not been tested under air pressure. There are minor age/storage marks, and the clear coolant tubing has become sticky/tacky from long-term storage. The original box and literature show age, staining, creasing and general shelf/storage wear.
Representative photos are shown. Cosmetic condition, tubing discoloration and packaging wear may vary somewhat between units.
Price is for ONE Model 20-S unit with original box and period Monroe literature
