Although Chicago Pneumatic Tool Co. was best known as a maker of handheld pneumatic power tools—which are not within the scope of this website—they also made boring machines, sanding machines, bench grinders, tool post grinders, gas engines, and semi-diesel engines. They were in business 1895 through 1946, and probably before and after that range.

Please note that this web site is focused on machinery, and we cannot provide more information on this maker's handheld power tools.
