DRILLING WOOD

In addition to the instructions listed under GENERAL DRlLLlNG, the following also apply:

1.When using twist drills in wood, they should be withdrawn from the hole frequently to clear chips built up in flutes to avoid overheating and burning work.

2.If a backing block is used to keep back of work from splintering, it should be clamped securely in place. If a backing block is not used with spade bits or hole saws, ease up pressure as soon as bit point breaks through work, and complete the hole from the opposite side.

DRILLING METAL

In addition to the instructions listed under GENERAL DRlLLlNG, the following also apply:

1.Use only good quality sharp high speed steel twist bits when drilling metal.

2.Start drilling with slow speed and gradually increase speed as drill cuts. The harder the material, the slower the speed required. The softer the material, the faster the speed.

3.When drilling a large hole, it is easier to first drill a smaller hole and then enlarge it to the required size.

4.The use of a lubricant, such as oil, on the drill point helps keep the bit cool, increases drilling action and prolongs drill bit life.
