This can be used to speedily and efficiently drill
holes when the drill bits which are being used are
greater than 4 mm in diameter.
This can be used to drill holes into wood or metal.
CAUTION:
Do not drill holes in wood with the "SAVE" mode.
There is a likelihood that the motor will burn out
because it can easily lock up due to the low power.
