Drillingoperation
0 Drilling inwood
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 intothe workpiece.
To prevent the bitfrom slippingwhen starting
a hole, makean indentationwith a center-
punch and hammer
at the point to be drilled. Place the pointof the bitinthe indenta-
tion and start drilling.
Use
a cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
0 Drilling inmetal

CAUTION:
0 Pressingexcessively on the tool will not speed upthe drilling. Infact, 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 bitbegins to breakthrough the workpiece.
0 A stuck bit can be removed simply by setting the reversingswitch to reverse rotationin
order to backout. However,the tool may back out abruptly if you do not hole
it firmly.
