Colonial Broach Co Detroit Michigan Paperweight - Colonial Broach Company was a manufacturer of broach tooling and machinery. Per online resources: Broaching is a machining process that uses a toothed tool, called a broach, to remove material. A broaching machine removes material - metal or plastic - by pushing or pulling a multi-toothed, graduated cutting tool - a broach - over or through a raw material in a single stroke. History: The company was founded about 1917 as the Colonial Tool Co., changed their name to the Colonial Broach Co. in 1929 (after acquisition - maybe, it is not clear to us), and returned to the Colonial Tool Company name in 1993 after being acquired by Textron.
