Using a speed control on a grinder?

Have a Dayton made Craftsman 7" bench grinder. 3450 rpm., 4.4 amp, 110 volts. Induction motor of course.
Would a fan speed control or light dimmer work to slow the speed without harming the motor?

Are you replacing a on/off switch with a variable speed switch or replacing a broken variable speed switch with a cheaper non name brand variable speed switch?
If it is the last one then no it wont hurt it. If its the first then yes it will work but id be afraid to try it on a good grinder just because it wasn't made for it.
