But first things first:
The packaging of the outside can be seen a few pictures puzzles which can be seen that
- The drill is to be set at a slight angle at the beginning to prevent bleeding
- Is to be drilled with 1500 rev / min
- No water should be used for cooling
A written manual, possibly with further tips does not exist.
In compliance with the instructions I have low pressure (I do not know if that's right, but I wanted to be cautious times) drilled in stoneware.
After about 5 mm depth, I've found that the hole is getting wider, which were then about 8 mm, but not deep.
A look at the drill shows that many diamonds, which are located on the side, all of which are still in great excess, the diamonds Vorndran who will have to work, but are no longer available.
Ie total loss after less than a hole!
Apart from this, the drill bit in itself has a diameter of 6.5 mm. How to order drill 6mm holes, it is not clear. When drilling with Diamanbohrkronen is yes also recommended a slight gyros with the drill, thus making the hole, of course, already a bit bigger.
Conclusion: EUR 27 for half a hole output, which also was still too wide then.
How is better, I'll describe diamond drill at the "Rhino Impact".
Here is a short preview: Since the piece will cost one tenth of the price demanded here and holds at least eight times longer.
So I guess that it was not because of me, that the Bosch drill has completely failed.
