Hi all, I'm new to this site so apologies if this question has already been asked. I have a 240 volt makita die grinder & i would like to reduce the spindle speed to accomadate a rotary wire brush, which is not suitable for the current spindle speed of my die grinder. Is there such an accessory available in the UK that i can just plug into the mains supply then plug my die grinder into the speed reducer? Many thanks in anticipation, yorky2010
