I used it very little and at some point I left the drill (device) with the tip upright on the floor (the battery was touching the floor). The wind blew and the drill simply tipped over and the tip broke as if it were a toothpick. I don't know what material it is, but at 3mm thickness it is very fragile.

As a drill, it is good. I recently used it for a job with iroko wood. I have bought it twice, the disadvantage of it is that it has two side screws that hold the drill in place, these loosen and you simply lose them afterwards..!
