Poly Products made a bench grinder, labeled, "POLY PRODUCTS" and either "MONROVIA, CALIF" or "PASADENA". They were intended for rock grinding. Poly Products also made saw (or disc sanding) arbors that were advertised for sale in 1946-47 issues of Popular Mechanics.

From October 1946 Popular Mechanics

Other than the 1946-47 data points mentioned above, we have not been able to narrow down their years of operation. Based on scant evidence from searching old trade journals, It would seem that they ceased doing business during the 1970s or '80s.

Information Sources

  • Thanks to Jukka Konola for bringing this maker to our attention.
  • Thanks to R. E. Rinker for providing additional information: that they were also in Monrovia, and that they were likely used for rock grinding.
  • A Google search did not turn up any information on a "Poly Products" company that might have made a bench grinder.
  • A patent search did not find any patents to a company by this name, although several companies had "Poly Products" as part of their name.
  • A Monrovia, CA, company named Poly Enterprises is completely unrelated to Poly Products; the presence of "Poly" in both companies' names is just a coincidence.
