Drilling in metal
Punch a small hole in the metal to prevent
the bit from skittering when starting to
drill a hole.
Use cutting lubricant on the bitto facilitate
drilling if necessary.
Pressing down too hard on the tool will not speed up the drilling. In fact, this undue pres-
sure will only serve to damage the tip of your drill bit, decrease your drilling performance
and shorten the service life of the tool.
There
is a tremendous force exerted on the tool/bit at the time of hole break through.
Grip the drill firmly and exert care when the bit begins to break through the material.
