I'm researching jackhammer chisels/bits/points for a school project. Almost every brand has a colorful way to describe the material its product is made out of. I've seen fast steel, hammer steel, a chemical code that just meant "steel", carbon steel, etc. For the purposes of the project, let's assume that I'm breaking up a sidewalk with 60-70 lbs jackhammer with a moil point attached. Does the type of steel actually matter, or are all of these names just marketing? I'm not noticing any significant variations in price based off of the material used. Also, do you know if in the United States there is any certification of quality required for these parts, either from a state agency or from a third party? There doesn't seem to be any such requirement in the EU.
Thank you
