How does this differ from a Dremel or other rotary tool, Don? I mean, will you get different results with this, compared to using a Dremel with grinding bits and wheels?
Don's key point is "Smaller & Lighter" which I would concour with...
I have several, for different purposes:
One mains powered runs 10-25,000 revs, powerfull enough to cut through shelves.
Second, mains powered UK version of Dremmel, with an electronic speed controller, 0-15,000 revs, though it 'pulses' between 0-1000 rev, used to drill small holes carefully
Third, a 2 AA battery powered $/£/€ store special, used as a paint stirrer/grinder/polisher, BECAUSE it is low speed & Low Torque.
Forth, a battery powered toothbrush, modified with stickypads as a rotory sander.
Fith, an 18V battery contractors' drill... low speed bodgers lathe, etc...
I have others as well....
