  • The torque of cordless drills below 24v is too low and not recommended
  • Hard material drilling needs to be cooled down with water, otherwise, it will burn the drill bit
  • Do not hit the rebar during use, it will cause the edge chipping
  • Metal, glass, gypsum board, and concrete are forbidden to use
