Bought this recently from Screwfix.Battery operated. First impression when I used it was that it sounded a bit "tinney". I drilled a 22mm hole in a wall and could immediately feel the heat eminating from the motor.My existing 24 volt Bosch (battery operated) did this effortlessly (which I have for 24 years). Ca, nt see my latest aquisation living up to its 24 volt cousins workload. Curious to know others views on it
