The similar HR2811FT is full of reviews, but this one had none. It's strange that people take the HR2811FT with a replaceable drill chuck. What will they drill at 1100 rpm? For metal, you need 2500, and reinforcement can be passed with a 4-lead drill. Larger screws are best driven with an impact wrench. Do those who buy a hammer drill for 18 tyr not have a drill or at least a screwdriver? I have everything from Makita, and now the Makita HR2811F Rotary Hammer.
