DeWalt D21002-XE, Instruction Manual

To release the locking mechanism, depress the trigger fully, then release it. Before 

using the tool each time, be sure that the locking button release mechanism is 

working freely.
Do not lock the switch on when drilling by hand so that you can instantly release the 

trigger switch if the bit binds in the hole. 

VARIABLE SPEED TRIGGER SWITCH 

This switch permits speed control: the farther the trigger is de pressed, the higher the 

speed of the drill.

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 for using abrasive and polishing accessories.

REVERSING LEVER 

The reversing lever (B) changes the direction of rotation of the drill and is used when 

backing out screws and jammed drill bits. 
To operate the tool in reverse, release the trigger switch and push the lever to the 

left (when viewed from the chuck end) as shown in Figure 2. To operate the drill in 

forward for drilling holes or driving screws (as well as when using other accessories) 

release the trigger switch and push the lever to the right (when viewed from the chuck 

end).
Return the reversing lever to the forward position after all operations in reverse are 

completed.

OPERATION

WARNING:

Shock Hazard. 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.

WARNING: To reduce the risk of personal injury, ALWAYS 

ensure workpiece is 

anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to 

prevent damage to the material.

Drilling

  1.  Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, 

spade bits, power auger bits, or hole saws. For METAL, use the low speed setting 

and steel twist drill bits or hole saws. For MASONRY, such as brick, cement, 

Motor Brushes

WALT uses an advanced brush system which automatically stops the drill when the 

brushes wear out. This prevents serious damage to the motor.

Switch (Fig. 1)

To start drill, depress trigger switch (A); to stop the drill, release trigger. 
To lock trigger in the on position for continuous operation, depress trigger and push
