I am very spot that perfo. Very effective for drilling holes in concrete. Very good result for the work of chiselling little (eg remove coating on qq m²). Vibration quite reasonable (no pb with my carpal tunnel) Excellent drive controller escalation which allows a very good drilling precision. Only complaint does not fit into the L-BOXX with automatic chuck. I'm really counting this perfo and regrets not having been able to buy more early.
