I am a die Setter in a large plastics factory and have quite a few mold changes everyday 6 days a week using brushless motor 1000 foot pounds of torque impact I am very rough on all my tools and most don't even last a week these sockets through heavy regular use for almost 2 months is barely even showing ware even on the 14 millimeter but I had to cut in half to be able to fit into tight spots still is not even slightly rounding off on the edges very high quality I will buy grey pneumatic sockets every time from now on for all of my impact socket needs
