A heating device for cutting tools has an outer casing, a power source, a cover board, a magnetizer and two conductive coils. The outer casing has an opening. The cover board is mounted securely on the top of the outer casing to cover the opening and has two through holes communicating with the opening. The magnetizer is mounted in the outer casing and has a conducting body. The conducting body is mounted in the outer casing, extends in the through holes of the cover board via the opening and has a middle and two free ends respectively extending in the through holes of the cover board. The conductive coils are respectively mounted around the free ends of the conducting body, abut the cover board and are electrically connected to the power source of the outer casing. |
