The machine corresponds to what is expected for its quality and power. As against the big big problem is the chuck. No possibility to pull out to put a conventional chuck. You have to buy a mandrel and then you are given a good old backward with conventional chuck (with the old key) whether automatic chuck it is extremely expensive. In other words to break a wall that is a very good product, but to a simple hole if you have a good old wick (not sds) and truly here you can not. I remain very disappointed !!!
