M.SR Motor Description: Foredom's 1/6 HP, universal, flexible shaft machine runs in forward and reverse rotation at speeds up to 18,000 RPM. The M.SR combines the most important features our customers expect - power, reversibility, reliability, and versatility - all in one motor. It comes equipped with a motor bale for hanging, and our standard 39" long key-tip shafting for connecting to any of the Foredom interchangeable, quick disconnect handpieces. C.EM-1 Speed Control Description: The C.EM-1 is a solid state control in a plastic housing that can be positioned anywhere on a work surface. The hand dial is used to adjust and set speed. This manual style control allows you to maintain and return to a desired speed, time and again, by using the motor on/off switch rather than the speed control to power up the unit. The C.EM-1 also has a replaceable fuse that protects the electronics during power surges and work overloads.
