Cuturi air hammers come in different sizes (different size pistons) and two types. The roughing hammers take larger chisels shaft diameters. The finish hammers take smaller chisel shaft diameters. Depending on your needs, you will probably want a large, medium, and small hammer for roughing, and then a medium and small for finish work. If you don’t use a diamond bladed saw for the initial stage of the rough (getting rid of big chunks of stone), you may want the largest air hammer for your initial rough but it’s very heavy and exhausting to use.
