Use with mixing drills, or grinders to reduce speed electronically without reducing torque.
20 Amps Max
This handy device will slow down your grinder or your mixing drill.
You can now use a regular angle grinder for polishing or edge polishing with our quick change system.
The dial lets you select any speed under 4000 Rpm. Will not work on slow start tools.
Three speed settings: variable, full & off.

It is just the bomb that it will handle up to 15 Amps, which covers so many different heavier duty motorized hand tools. It let me retrofit one piece of equipment that would have been way too fast otherwise, that had almost all the attributes needed for another completely different service function.
