It works fine, it's just that if you push it a little too hard, it loses its teeth and stops working.

A lot of music for little money - really! Very good drill bits (I have tried 6 and 8 mm) when you need to drill into sintered tiles. I have a fresh comparison with Bosch Hard ceramic drill bits (6 and 8 mm, much more expensive) and where with the Bosch drill bit I drilled the hole in 20 minutes (I am not exaggerating) I had it done in about 45 seconds max with this diamond hollow drill bit). You need to learn where to drill the thread so that the resulting hole is where you want it (with the drill bit you have to start drilling at an angle from the edge and gradually lean into a position perpendicular to the tile. Otherwise the drill bit is very difficult to cut). Once the drill bit has drilled a complete intermediate ring, the drilling goes quickly with a circular motion of the drill. It is necessary to keep the drill bit cool at all times (! ) either by drilling in a tub of water (you can make a gaff by sticking it on the wall), or by constantly spraying water (I used a flower spritzer and the help of my partner).
Quick
clean hole without chipping
can drill through even very hard tiles
cheap
must be rinsed/cooled continuously
drills only pavement (concrete and itong can't handle it)
it is necessary to learn how to estimate the position of the hole

I recommend to pre-drill a little with the KREATOR Drill for tiles and glass 8 x 80 mm
Works reliably
8 holes in the ceramic tiles ripped out without any problems
at an affordable price

It drills beautifully even in very hard tiles, it is hollow, so it can be cooled with water. I have a comparison with Festa and this works much better. Ideally in combination with a spike drill to make an accurate hole and then mill the rest of the paving with this. For the money, great!
price/performance
works better than FESTA
missing instructions, need to search
if you want a precise hole, it's better to use a spike drill first
the hole on the side is narrow and the material was more likely to come out the other end

A lot of music for little money. Holes in hard stone 2cm terrace paving drilled without any problem and without any stimulation. After about 5 seconds I cooled the crown in water.
The vice shank holds perfectly in the chuck
