Drilling in metal
To prevent the bit from slipping when starting
a
hole, make an indentation with
a
center-
punch and hammer
at
the point to be drilled.
Place
the point of the bit in the indenta-
tion and start drilling.

a
cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.

.Pressing excessively on the tool will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your bit, decrease the tool performance
and shorten the service life of the tool.

at
the time of hole break through.
Hold the tool firmly and exert care when the bit begins
to
break through the workpiece.
