i bought this set some time back and it is a quality set of SDS bits and the price is right. i don't use SDS every day, but do use them a good bit and they haven't dulled and believe it or not, i have not lost one yet. good deal.

What is there to say about these?.. If you put them in a Bosch "Bulldog" rotary hammer, they go through concrete like a hot knife through butter. Unless you are a using these professionally, it seems unlikely that you would ever wear them out. I can't detect any wear on the carbide tips on any of mine with the exception of some minor wear on a larger one (not part of this set) that has about 100 6" deep holes on it.

I bought these to use with a Bosch Rotary Hammer that I purchased. Hammer uses the SDS Max bits, so I also purchased the SDS Plus adapter to use these bits. They work great and (using my heavy duty rotary hammer) will go into a concrete wall like butter. Definitely worth the money.

The drill bits are of very high quality at a good price. Used them on old concrete and the holes drilled like butter.
