The Industrial and Scientific Chisel Jackhammer is supposed to make hardscaping tasks easier. Unfortunately this expensive chisel yielded no better results than an inapt hammer and chisel combo. Thanks to my knowledge gained in practice, I can say that this heavy-duty tool was a severe letdown .The pros are its size and weightlessness, but its inefficiency in removing stubborn thinset is a significant disadvantage. Overall, I am not content with this product..
Pros
Efficiently and quickly removes thinset from surfaces.
Cons
May cause damage to the surface if not used carefully.
