back in the day, my brother did basement repairs and, as far as i know, that was the only thing he used this tool for he'd patch foundation wall cracks by enlarging existing cracks to set a good grout in place then, my brother stopped doing indoor concrete work and switched to outdoor work - heavy equipment this tool has not seen any use for a number of years - only being sold bc he passed tested unit - works great - https://streamable.com/yzu9ap - if video is expired, just lemme know and i'll repost it * very solid construction - hefty - mac built * sounds right when firing * includes more bits than the original kit as far as i can tell, this tool is ready to tackle the next challenge
