Today I received the drill (750 watts, 1.60 meters in height, price 400 euros).
Easy to assemble, the only tool you need to have to attach it is a 17mm wrench, everything else is included. I had a high-quality chuck and did not use the one already included in the package because it has a minimum of 5mm and a maximum of 20mm, which personally doesn't suit me as I use drills smaller than 5mm. It seems to be of good quality and it appears that some attention has been given to its construction because during assembly I noticed that all the bearings are sealed and the inside of the column has been painted with enamel.
I measured the play that the drill has during operation with a precision engineering caliper and to my surprise, I found it to be only 2 millimeters. All the surfaces that come into contact during assembly have been milled, resulting in a perfect fit. The only flaw I noticed is that there is play in the front pulley, which is seated on the drill's axis, but this may disappear with the use of adhesive bearings. I give it 5 stars because finding only 2 millimeters of play is not something you find even in professional drills. I recommend it for purchase.

For amateur use, it is good, quite sturdy, and has a laser for alignment. The choke is automatic but not very effective, and it has a terminal that does not work when the lid with the pulleys is open. You get what you pay for!

Tragic that it does not have a handle on the table. There is nothing that matches it in the market. This makes it inconvenient and dangerous many times. However, its motor is good and can easily make holes up to 20mm, but it manages to do it.

Very sturdy machine. Everything is good but there is only one thing I don't like very much. Personally, I would like it to have a more stable chuck. This one has a bit of play. However, it's not something significant. The good thing though is that you can change drill bits very quickly and easily without needing a key for the chuck. Also, I would like them to include a handle with the machine for drilling. Other than that, the machine is very powerful and its base is perfect without the slightest "flexibility" and perfectly perpendicular to the rest of the tool. At this price, I consider it the best purchase for a column drill.

It's a beast! For its price, it's very good, powerful, and reliable! With the proper settings, it does a great job.
