They have a few different cordless models. If you get one of those, get the Li Ion model. They are miles ahead of the ni-cad battery models. They have corded models also. I can't stress enough that the Dremel's are made for light duty, small, intricate work. Sure you can cut off a bolt occasionally or do some die grinding with a carbide burr but they aren't made for HD use. Here's a good HD corded electric die grinder with a 1/4" collet. It's a model 887. Home Depot sells them for around $130. tmm
