Not long before his death Dr. Isadore Goldstein requested me to construct for him a few instruments, and the one described here was made at his suggestion.

The construction of this device was rather simple. An ingenious battery-driven revolving fan, made on the Continent, was deprived of its blades and in place of them a cylindric collar was attached, into which the operator could readily insert any of the standard dental burrs. The handle itself is a somewhat compact unit, consisting of a generator operated by two batteries. The entire outfit occupies surprisingly little space. The speed of this motor was found to be satisfactory for general requirements—about 500 revolutions per minute—and could be readily reduced by the simple application of the index finger to the projecting rod. The whole unit can be easily held in the hand.
