How can I find if an impact energy of 2.7 J is enough for chiseling concrete slab ? I am thinking about purchasing a Bosch GBH 240, which has an impact energy of 2.7J. Please let me know if this rotary hammer has enough impact energy for chiseling an 10 cm concrete slab ?
I need this rotary hammer for jobs around the house, for example chiseling an 10cm concrete slab which has an area of about 0.25 sq meters, for drilling holes into concrete walls (6 to 12 mm diameter holes) and other things like that. I am in an renovation process in my house.
