Dear friends of skroutz.gr, today I took the tests and passed with a score of 98/100.
A) I wrote a month ago that the chuck has small tolerances, but in the design of vertical expenses, this tolerance is an advantage because... when we aim with the point on a metal surface as required before drilling, then we have to align the drill with the point. Now, in order to center it at 100/100, you need magnification at the point... and that's what I did. I adjusted the tripod, placed my phone on it, and zoomed in x30. I could see the aiming point x30. I lowered my drill 3mm at the point and there the advantage of the chuck's small tolerance became apparent. As soon as I lowered the drill, it locked itself in the aiming point and went down, correcting any deviation from the vertical alignment at the point... 230 rotations and it cut through like butter.
B) Then I drilled with an 8mm drill bit and again this small deviation corrected the alignment and the drill centered itself and went down smoothly... after measurements I made on the adapter for the lathe chuck, which is 160mm, I had to make the final cut with a 9mm drill bit and again it corrected itself and made a precise cut right at the center, 99.9% accurate. That's when I realized that these small tolerances of the chuck are really crucial.
FINAL... I made the adapter and adjusted the SA NOU 160mm chuck with a measured deviation using a hundredth of a millimeter watch, with a measurement of 1/100 of a millimeter!!!! Even with a laser cutter, I wouldn't have such precision. In a few hours, I will upload photos for you to see... it gets an excellent rating from me because a) it has a 3-year warranty, b) it is sturdy, c) it has a laser and lighting mechanism, d) it has electronic speeds without variable gearing, from 230 rotations per minute to 2500, e) it is ergonomic with an arm for securing the object for processing, f) it has tube nests for centered drilling in pipes, and g) it is beautiful and truly sturdy, drilling from 1.5mm to 13mm in metal and up to 40mm in wood...! I also forgot to mention the electronic meter on the dial with a clear indication of cutting depth, a large screen, and maximum cutting depth!

Before I describe, let me mention that I work with wood. Not just soft woods like pine and fir, but hard ones like walnut, chestnut, and oak.

Exceptional, one of those tools that you enjoy using. The ease of changing speeds, adjusting depth, and its stability make it worth 100% of its price.
A very important positive aspect is the drilling capacity, which is 9 centimeters. No other vertical drill in this category has this feature.
Regarding power, I will mention the following: with a 4-centimeter diameter Forstner bit, it drills through any wood I have used. Of course, always using the correct technique for using these bits, meaning slow speed and lubrication with wax (for hard woods). Naturally, with quality bits (I use Wolfcraft, there are clearly much better ones available).

If you are thinking of buying a vertical drill, seriously involved in woodworking and have a limited budget, I would recommend getting this instead of the usual ones in the 150-200€ range. You get back the price difference in much higher quality.
