I had to buy another kit that had the EZ-Connect attachment and about 100 other pieces I'll never use. I thought I was all set for my project but had to run back and drop another $50 on the add-ons. That's pretty frustrati...

Dremel 8240

Would Recommend

Works fairly decent, just have to get use to the fact that you have to be patient and take your time while drilling or cutting. Can't try to push it to hard, will cause it to cut off, so have to restart.
