There is no problem normally drilling in concrete, because it is a maker goods, on price home center, but there is also cheap, in the case of the purchase at the time of the discount to be there Shi expenses processing cases to become a low-cost is very convenient is there
You can drill precisely. I think that it is difficult to use it all the time because it is a cutting edge consumable item ... I think that life expectancy is different depending on the number of times to open a deck etc.
I will cast an anchor bolt on the wall of an apartment with renovation work.

The SDS plus bit is handy for easy exchange of cones by hand. When there is work to drill holes in the steel plate, not only in concrete, there are times when the circular cone gets idled. If SDS plus bit, there is absolutely no idling so workability is good. For hexagonal awls for concrete, it is necessary to prepare two drills and workability is bad.
