Drilling operation
When drilling in wood, metal or plastic materials, depress the action mode change but-
ton from the side with
& Q Q
symbol to use "rotation only" action.
*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 drv.
*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 twisting force exerted on the tool/bit at the time of hole break-
through. 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 holddown device.
