KSP-TEC® | Carbide - Cross Tipped SDS-Plus Rotary Hammer Drill and Chisle Bit Set with Storage Case for Masonry, Concrete, Brick, Stone

gone through concrete and brick and so far these work flawlessly. I used them in a handheld chipping hammer & each bit worked as expected. No deterioration or wear to these bits so far. They've held up very well. I'm not removing patios or very long sidewalks but they do not stutter or get hung up on any concrete (yet). Good quality

Good drill bits worked well

I had a small cement pad in my back yard that I was wanting to break up. I had tried to break it up with a sledge but made very slow progress. I thought I'd try using my rotary hammer to break it up instead. I looked at several different bits and reviews and almost went with a more expensive name brand, but decided to give these a try for the price. A few reviews said they held up through one project but were pretty wore out after. I had expected to have one break or wear down at some point but didn't have any issues with the bits at all. These bits far exceeded my expectations, not only did they finish the job, but they held up just fine. I was able to do some more jobs with the bits as well. For the price and quality of these bits they are well worth the money. I would highly recommend.

One of the drill bits broke off in the concrete, but other chisels worked great

I bought this bit set because I needed to drill a few holes through my brick siding. Even though it is more of an attached sheet, it still seems to be made from brick material. My normal hand-held hammer drill was not powerful enough, so I needed to use my demolition hammer - which required SDS bits. Once I had the SDS bit attached, it when through like butter. I would recommend these!

Great set for the price. Not up to milwaukee or Diablo standards but for the price I think its a good deal. NOTE I DONT USE THEM EVERY DAY JUST ON occasion
