I sent in a blast, core, and surge to be repaired and they are coming sometime tommorow! I send them in because they were my some of my beater tools and they were getting pretty banged up. I broke the main blade off the blast prying. The tools on the core came out easily when I flipped it open ( simlar to def's problem), and the surge is missing the bit retention spring on the main bit driver. I really beat the crap out of my tools!
