Review on 🔨 AOBEN SDS Plus Vibration Demolition Concrete Including: Effortless Concrete Breaker for Superior Performance by Doug Layman

The AOBEN SDS-Plus rotary hammer was disappointing when it arrived as it does not have a 3 pin earth plug despite the seller's answer to the question. If I had known that before unpacking, I would have gone straight back. Also, it arrived with a good set of sturdy bits as described and has worked well for about 2 hours of heavy use so far. The manual doesn't seem to say that grease and oil aren't the same thing, so I added as much grease as I could into the grease hole and the drill seemed to work fine. The odd layout of the settings is confusing and it took quite a bit of figuring out how I did it as the instructions are almost useless in that regard. The drill is very powerful and feels good in the hand, the movable handle works great and the hammer function is very effective when chiseling concrete and very hard (compacted) dirt. The chuck picks up and releases bits easily (I lightly greased the tips) and the drill chuck, which you can use for regular drills and bits, works well. The torque protection and vibration suppression features worked well, even better than expected. But there is no real ground wire - NOT GOOD!
