Ok magnetic drill. Purchased to get me through a specific job. Used the drill chuck with hole saws. Got the job done but when backing the hole saw out of the work piece the quick release chuck came loose too often, dropping the drill chuck, adapter and hole saw. I'm not sure if this is an issue with the drill chuck adapter or the quick release mechanism. I haven't tried any of the boring bits that come with the drill press to see if their arbor adapter does the same thing. All of the boring bits with this machine are metric. I would have preferred to buy just the machine without the metric boring bits.
