Jancy mag drills offer dependability, safety and versatility. Only Jancy offers integrated safety shields and "Smart magnet" circuitry that does not allow the drill motor to turn on in unsafe magnetic holding conditions. Smart Magnet circuitry will also shut down the drill motor in the unlikely case of the drill breaking away from the workpiece. Jancy portable magnetic drills are made in the USA and come with a 1 year factory warranty.Expires Dec 15, 2010
