Drilling in wood
When drilling holes in the wood, use a wood drill with a guide screw. The guide screw
makes it bore naturally by itself, so you do not need to apply any pressure to the tool.
To prevent the bit from slipping when starting
a
hole, make an indentation with a center-
punch and hammer
a t
the point to be drilled. Place the point of the bit in the indenta-
tion and start drilling.
Use
a
cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.

CAUTION
:
.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.

Hold the tool firmly and exert care when the bit begins to break through the workpiece.

.A stuck bit can be removed simply by setting the reversing switch to reverse rotation
in order to back out. However, the tool will pull away easily unless you hold
it
firmly
before starting the tool.
