DREMEL - I have several. I love this power tools because they are small, easy to use and I can do almost anything that needs to be done without the bulk. From cutting copper pipe for doll armatures, sanding or cutting wood for frames, to drilling holes in glass I've found a bit or tool for it. AND, DREMEL STANDS BY THEIR PRODUCTS. If something goes wrong, they apologize get it back to you right away AND you get an extra bit 'ta boot!
