WARNING:

Be prepared for binding at bit breakthrough. When these

situations occur, the drill has a tendency to grab and kick

in the opposite direction and could cause loss of control

when breaking through material. If not prepared, this loss

of control can result in possible serious injury.

 When drilling hard, smooth surfaces, use a center punch

to mark the desired hole location. This will prevent the

drill bit from slipping off-center as the hole is started.

 When drilling metals, use a light oil on the drill bit to keep

it from overheating. The oil will prolong the life of the bit

and increase the drilling action.

 If the bit jams in the workpiece or if the drill stalls, stop

the tool immediately. Remove the bit from the workpiece

and determine the reason for jamming.

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.

OPERATION

 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.

WARNING:

This product and some dust created by power sanding, sawing, grinding, drilling, and other construction activities may

contain chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive

harm. Wash hands after handling.

Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products and,

• arsenic and chromium from chemically treated lumber.

Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your

exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially

designed to filter out microscopic particles.
