"I picked the higher wattage (1250w) version of this model and it paid off. I put it through a grueling test coring 125mm on an 18" Manx Stone wall. On another plus side it has a soft start motor, which ran on ok on the off-grid (Wind turbine battery bank) power inverter on site. So would be ideal on a small generator."
"Clutch comes in way too soon. I only drill holes up to 52mm and it is poor. Its not bad on stone but terrible on brick especially if there is any dampness. Got stuck halfway through a wall and took about an hour to get it out. Clutch just spinning."
