I recently started a new job which required me to buy an impact wrench. I purchased the Craftsman 875 model at my local Sears store. I’ve only had it for one month and couldn’t be more disappointed with it’s reliability. 3 out of 6 vanes broke within the pump after a month of usage. Plastic vanes were used in place of metal ones. When the gun was working, it felt very nice in the hand in both size and weight. If you want quality tools, look else where.
