I have a R7120 Spade Drill which I recently purchased. Very strong drill. My only issue is that I need it to sping at 300 RPM when mixing thinset mortar. 2 questions. Does the speed when mixing drop from the 500 rpm no load when mixing with a big paddle bit? Is there any kind of electric speed reducer available.
since no one who is looking over this forum,i will tell you when undetr a load the speed drops. there is nothing you can add to the tool but a transformer box that your tool pluges into and you adjust it with a speed dial.
