WOOD DRILLING

For maximum performance, use high speed steel bits for

wood drilling.

 Begin drilling at a very low speed to prevent the bit from

slipping off the starting point. Increase the speed as the

drill bit bites into the material.

 When drilling through holes, place a block of wood behind

the workpiece to prevent ragged or splintered edges on

the back side of the hole.

METAL DRILLING

For maximum performance, use high speed steel bits for

metal or steel drilling.

 Begin drilling at a very low speed to prevent the bit from

slipping off the starting point.

 Maintain a speed and pressure which allows cutting

without overheating the bit. Applying too much pressure

will:

• Overheat the drill;

• Wear the bearings;

• Bend or burn bits; and

• Produce off-center or irregular-shaped holes.

 When drilling large holes in metal, start with a small bit,

then finish with a larger bit. Also, lubricate the bit with oil

to improve drilling action and increase bit life.
