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

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

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

pressure 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

a t

the time of hole break through.

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

*Always grip the small workpiece firmly with a

vise

or a holding means.

* 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

firmly

before starting the tool.
