When driving wood screws, predrill Pilot
holes to make driving easier and to pre-
vent splitting of the workpiece. See the
chart.

Drilling operation
Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with
a
guide
screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
To prevent the bit from slipping when starting a hole, make an indentation with a
centerpunch and hammer
a t
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use
a
cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
Drilling in metal
CAUTION :
*Pressing excessively on the
tool
will not speed up the drilling. In fact, this excessive pres-
sure will only serve to damage the tip of your bit, decrease the tool performance and
shorten the service life of the tool.
*There is a tremendous force exerted on the tool/bit at the time of hole breakthrough.
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 may back out abruptly if you do not hold
it
firmly.
Always secure small workpieces in a vise or similar hold-down device.
