Offered for sale is a pair of combined Production Estimator and Spindle Speed Calculator look-up dials by Kramer. These are exactly alike. On one side the dial can be turned to a drill or cutter diameter and the RPM or surface cutting speed can be read from the face. On the opposite side the production calculator lists pieces per hour based on machine speeds, feeds, and depths. The text on the dials indicate these are manufactured by C.P. Kramer Franklin Park, ILL. These are unused and in like new condition. These are 3-5/8" diameter. Both sides are listed as copyright 1931. The pair of identical manufacturing machining dial calculators is interesting and unusual. You get both these estimators / calculators for this 1 low price! More than 1 pair available.
