The term Mixed Set Titanium suggests to the customer that it is in this article to a high-quality "Titan" product from Bosch. In my view this article Description borders on fraud. Both the 6mm and 8mm masonry drill bits have kept simple non-calcareous sandstone complained less than 2 minutes standing and are barely recognizable as a drill. The drill tip is fully annealed and deformed sometimes. Obviously a cheap product from the Far East. I can not understand the risk as a reputable company such as Bosch's good name with such a scrap. I have now bought two drills from the Hagebaumarkt that in itself hardly more expensive than this product was of "Bosch". The drills from the hardware store can be effortlessly even pierce concrete slabs. Conclusion: Hands wech of this waste.
