I realized that my Dremel bit the dust a couple of weeks ago when it wouldn't even cut a 2" PCV pipe. I went to Lowe's and the 400 was just a little more then the 300. (the one I was replacing was just a single speed tool…..not even a 100) Anyhow, I got to use it tonight. I was putting a windshield on Sly's bike and a bracket was in the way. Put on the cutting blade and man, like cutting through butter. If your Dremel is old, or if you just want a new bad a$$ tool, I strongly recommend it! Can't wait to figure out what I'm going to use it on next!!!
