Customer Reviews for VEVOR Clay Spade, 3.9" x 9.5" SDS Plus Shank, 40Cr Steel Jackhammer Bit for Electric Demolition Jack Hammer w/Point Chisel, Trenching and Digging Shovel Bit for Clay, Gravel, Frozen Soil
Can’t address how good this works on concrete but for breaking up hard clay dirt clods it worked wonders. This bit is quality and I’m sure it would perform its proper job on concrete.
I needed a square shaped shovel so could cut through tree roots in the trench I was digging. The spear point shovels just slide past them without cutting them.
This tool has performed incredibly for me. It has saved my back and feet. Great for digging out shrubs and for planting. Also great for trenching to bury low voltage wiring.
