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.

Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with acenter-
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 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 a t the time of hole breakthrough.
Hold the tool firmly and exert care when the bit begins to break through the workpiece.
.A stuck b i t can be removed simply by setting the reversing switch t o 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.
Hook
A hook is provided as a standard equip-
ment. This hook i s convenient for tem-
porarily hanging the tool.
To
install the
hook, first insert one end of the hook into
one slot in the tool body and then insert
the other end into the other slot. Secure
the hook with the screw. The hook can be
installed on either left or right side of the
tool.
