INTENDED USE
The
These
Switches (Fig. 1)
To start the drill, depress the trigger switch; to stop the drill, release the trigger.
A variable speed trigger switch (A) permits speed
NOTE: Use lower speeds for starting holes without a center punch, drilling in metal or plastics, driving screws or drilling ceramics. Higher speeds are better for drilling wood and composition boards and using abrasive and polishing accessories.
The reversing lever (B) is used for withdrawing bits from tight holes and removing screws. It is located above the trigger switch. To reverse the motor, release the trigger switch FIRST and then push the lever to the right. After any reversing operations, return lever to forward position.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attach- ments or accessories.
Drilling
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood
1.Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use
2.Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting, but do not push hard enough to stall the motor or deflect the bit.
3.Hold tool firmly with both hands to control the twisting action of the drill.
4.IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO
NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL — THIS CAN DAMAGE THE DRILL.
5.To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole.
6.Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming.
7.With variable speed drills there is no need to center punch the point to be drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out.
DRILLING IN METAL
Start drilling with slow speed and increase to full power while applying firm pressure on the tool. A smooth even flow of metal chips indicates the proper drilling rate. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry.
NOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel can be made easier if a pilot hole [5/32" (4 mm) to 3/16" (5 mm)] is drilled first.
DRILLING IN WOOD
Start drilling with slow speed and increase to full power while applying firm pressure on the tool. Holes in wood can be made with the same twist drills used for metal. These bits may overheat unless pulled out frequently to clear chips from the flutes. Work that is apt to splinter should be backed up with a block of wood.
DRILLING IN MASONRY
When drilling in masonry, use
Bubble Level – DWD110, DWD112, DWD115 (Fig. 2)
Your drill is equipped with a bubble level (C) that assists you in drilling level holes.
For horizontal drilling, tilt the drill up or down as required so that the bubble floats in the center of the parallel lines drawn on the glass. When the bubble is centered between the lines, the drill is level.
For vertical drilling, align the drill so that the bubble floats in the center of the

To assure accuracy, first place a level on your work piece and position it so that it is level. Then, when the drill reads level, the two will be aligned. (Any bubble level can only indicate level to the earth’s surface).
NOTE: The fluid in the bubble level vial is mineral spirits. If the mineral spirits gets into your eyes, flush eyes with water. If irritation occurs, seek medical attention. If the vial fluid comes into contact with your skin, remove contaminated clothing and remove excess fluid. Rinse thoroughly with water followed by washing with soap and water. If irritation occurs, seek medical attention. If vial fluid is inhaled, immediately get fresh air. If difficulty breathing, seek medical attention.
Keyless Chuck – D21007, D21008, D21009, DWD110, DWD115 (Fig. 3)
Your tool features a keyless chuck (E) for greater convenience. To insert a drill bit or other accessory, follow the steps listed below.
1.Grasp the rear half of the chuck with one hand and use your other hand to rotate the front half counterclockwise, as shown in Figure 3. Rotate far enough so that the chuck opens sufficiently to accept the desired accessory.
2.Insert the bit or other accessory about 3/4" (19 mm) into the chuck and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction. When the chuck is nearly tightened, you will hear a clicking sound. After
3 To release the accessory, repeat step 1 listed above.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result.
KEYLESS CHUCK REMOVAL (FIG. 4)
Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4" (6 mm) or greater size. Using a soft hammer or piece of wood, strike the longer end in the counterclockwise direc- tion. This will loosen the chuck so that it can be unscrewed by hand.
KEYLESS CHUCK INSTALLATION (FIG. 5)
Screw the chuck on by hand as far as it will go. Tighten the chuck around the shorter end of a 1/4" (6 mm) or larger hex key (not supplied) strike the longer end in the clockwise direction with a soft hammer.
Keyed Chuck – D21002
Open the chuck jaws by turning collar by hand and insert the shank of the bit about 3/4" (19 mm) into chuck. Tighten the chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise direction. It’s important to tighten chuck with all three holes. To release the bit, turn the chuck counterclockwise in just one hole, then loosen the chuck by hand.
REMOVAL OF KEYED CHUCK (FIG. 6)
Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4" (6 mm) or greater size. Using a soft hammer, strike the key sharply in the counterclockwise direction when viewed from the front of the tool. This will loosen the chuck so that it can be removed by hand.
KEYED CHUCK INSTALLATION (FIG. 7)
Screw the chuck on by hand as far as it will go. Insert the shorter end of a hex key (not supplied) of 1/4" (6 mm) or greater size and strike it in the clockwise direction with a soft hammer.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories.
