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

Srong tool - wish it would be made in USA

dam good hammer drill for the price as good as the one i used at work and cheaper. order the extra bits its wourth it.

Works great

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.

Bought as a gift, they work great

They,re good chisel used on flagstone and concrete
