Active between about 1951 and the early 1960s, RCS Tool Sales Corp. manufactured the Korner King and Super Saw portable drill attachments. We find the company name spelled three ways, as R.C.S. Tool Sales Corp., R. C. S. Tool Sales Corp., and RCS Tool Sales Corp. In addition, the RCS Engineering Corp. was a closely related business, operating from the same premises and with the same corporate officers.

The name "RCS" appears to be derived from the surnames of Francis S. Russell, C. J. Clark, and Thomas M. Sweeney.
