There is no problem at all as it is drilled in concrete as a manufacturer product at all, there are cases where the home center is cheap in terms of price, but in the case of purchase when purchasing at discount there are also cases where it is inexpensive and it is very convenient for expense processing 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.
