"I bought two of these drills, the first time i used it was to drill a 20mm hole in a 60mm x 40mm box metal,cut the first side no problem and as soon as it went through and touched the other side the drill bent badly. so i changed it for the second one i bought and it did exactly the same thing,the drill is far to long and to soft."
