Dremel EZ688-01 EZ Lock Mini Cutting Kit for Metal and Plastic (Tools & Home Improvement)

Pretty decent product. The quick change chuck is really nice, actually more secure and solid than the old screw types. And these cutting wheels perform really well. I use them quite a lot, and they are nowhere near as fragile as some of the stone chip based disks, and the skinny ones are really fantastic at keeping the heat buildup down. It's also nice to have the disks targeted at plastic material, as metal targeted disks always make a mess of plastic. The plastic targeted ones blow through plastic fast and easy, without a lot of stink or melted material, which is nice.
