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.
0Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with a 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 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 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 it firmly before starting the tool.
