Customer Reviews for VEVOR Clay Spade, 5.9" x 24.4" SDS Max Shank, 40Cr Steel Jackhammer Bit for Electric Demolition Jack Hammer with Point Chisel, Trenching and Digging Shovel Bit for Clay, Gravel, Frozen Soil
I used this bit to take an epoxy/pebble coating of the concrete. It does well, but the stones do dull the blade. It can be resharpened with grinder and will work as well.
Coupled with Bosch rotary hammer dill, this bit works great to chisel out mortar left from tiles. It also works great to break concrete slab (in small piece though).
