I found the bosch to break the nylon gear inside very easily. Great tool while it works, the one at work lasted for only a short time got repaired and failed again. I also bought one for home after thinking they were great only to have it fail in the same manner, wont be bying another bosch. The electric bosch drill burned out at work also where the dewalt battery drill finished the job. I used to think bosch was good but am now thinking they may be building down to a cost rather than up to a quality.
