Not as good as the Bosch or Milwaukee Carbide Bits that I have in both sizes, but sufficient. The carbide part is much thinner and smaller and they wear out much quicker than known options, but they still do the job if the carbide isn't worn out.
Pros
βοΈAPPLICATIONS: The SDS Plus Drill Bit is ideal for drilling concrete, masonry, stone, brick and other construction projects
