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 at 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.
CAUTION :
Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pres-
sure will only serve t o 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 t h r o u g h the workpiece.
A stuck bit can be removed simply by setting the reversing switch to reverse rotation in
order t o back out. However, the tool may back out abruptly
if
you d o not hold itfirmly.
Always secure small workpieces in a vise or similar hold-down device.
