Holding tool
CAUTION:
•This is a powerful tool. High torque is developed and it is important that the tool should be securely held and properly braced.
Grasp the switch handle with one hand and the spade grip with the other hand. When drilling a large hole with a self- feed bit, etc., the side grip (auxiliary handle) should be used as a brace to maintain safe control of the tool.
When drilling action is forward (clockwise), the tool should be braced to prevent a counterclockwise reaction if the bit should bind. When reversing, brace the tool to prevent a clockwise reaction. If the bit must be removed from a partially drilled hole, be sure the tool is properly braced before revers- ing.
Drilling operation
Drilling in wood
When drilling in wood, the 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 a
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.
