4)  Depress the trigger switch to start the drill.

5)  Move the drill bit into the workpiece, applying 

only enough pressure to keep the bit cutting.

Do not force the drill or apply side pressure to 

elongate a hole. Let the tool do the work.

6)  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.

7)  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.

8)  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.

NOTE: 

This drill is equipped with an electric 

brake. When the brake is functioning properly, 

sparks may be visible through the vent slots in the 

housing. This is normal and is the action of the 

brake.

       WARNING: 

Be prepared for binding at bit 

breakthrough. When these situations occur, the drill 

has a tendency to grab and kick opposite to the 

direction of rotation and could cause loss of control 

when breaking through material. If not prepared, 

this loss of control can result in possible serious 

injury.

                              APPLICATION                            

WOOD DRILLING

For maximum performance, use high speed steel 

or brad point bits for wood drilling.
1)  Begin drilling at a very low speed to prevent the 

bit from slipping off the starting point. Increase 

speed as the drill bit bites into the material.

2)  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.
1)  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.

2)  Begin drilling at a very low speed to prevent 

the bit from slipping off the starting point.

3)  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.
- Produce off-center or irregular-shaped holes.

MASONRY DRILLING

For maximum performance, use carbide-tipped 

masonry bits when drilling holes in brick, tile, 

concrete, etc.
1)  Maintain a speed and pressure which allows 

cutting without overheating the bit or drill.

Applying too much pressure will:
- Overheat the drill.
- Wear the bearings.
- Bend or burn bits.
- Produce off-center or irregular-shaped holes.
2)  Apply light pressure and medium speed for 

best results in brick.

3)  Apply additional pressure for hard materials 

such as concrete.

4)  When drilling holes in tile, practice on a 

scrap piece to determine the best speed and 

pressure.

Begin drilling at a very low speed to prevent the 

bit from slipping off the starting point.
