I purchased this light duty rotary tool as a stand in until I am ready to purchase a heavy duty one. Until then the tool should work for my light duty wire-brushing, cutting, buffing, sanding, grinding and drilling. In the way of sanding, it should make quick work on wood and plastic. The grinding stones will help me keep a keen edge on my other tools. And the drilling, well you know I have to drill a hole to attach a coupler on to the 7mm flat car.
