Iron button
The iron button function decreases the operation speed
to make it easier to cut in hard materials, for example
reinforcement bars.
The decreased speed can also be used to make it
easier for the drill bit to go into the surface of other
materials. For best performance, disengage the iron
button function when the drill bit is through the surface
and drill the hole at regular speed.
