Installing and Releasing a Bit
Open the keyed chuck
10
jaws by turning the collar by hand,
then insert the shank of the bit about 19 mm into chuck.
Tighten the chuck collar by hand. Place chuck key
11
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.
NOTE: When using hex shank or three-sided shank bits, be sure
to align the flat sides of the bit with the chuck jaws to ensure
the bit is properly engaged by thejaws.
Worklight (Fig. A)

CAUTION: Do not stare into worklight. Serious eye
injury couldresult.
The worklight
8
is located on the D-handle. The worklight is
activated when the trigger is depressed, and will remain on for
a short time after the trigger is released. If the trigger remains
depressed, the worklight will remainon.
NOTE: The worklight is for lighting the immediate work surface
and is not intended to be used as aflashlight.

WARNING: Read instruction manual for the
DeWALT
Bluetooth® ToolTag.

WARNING: Remove battery from tool before installing the
DeWALT
Bluetooth® ToolTag.

WARNING: When installing or replacing the
DeWALT
Bluetooth® Tool Tag, use only the screws provided. Be sure
to securely tighten thescrews.
Your tool comes with mounting holes
13
and fasteners for
installing a
DeWALT
Bluetooth® Tool Tag (DCE041). You will
need a cross head bit tip to install the tag. Screw torque should
be between 0.8 and 1.2 Nm (7.1 to 10.6 in-lbs). The
DeWALT
Tool Tag is designed for tracking and locating professional
power tools, equipment, and machines using the
DeWALT
Tool
Connect™ app. For proper installation of the
DeWALT
Tool Tag,
refer to the
DeWALT
Tool Tagmanual. To learn more,visit:

OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can causeinjury.
Proper Hand Position (Fig. H)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position asshown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
suddenreaction.
Always hold tool firmly with both hands in the proper position
for operation asshown.
Drilling

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.
1. Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, power auger bits, self-feed bits, or hole saws. For
METAL, use steel twist drill bits or hole saws. For CONCRETE,
use dry core drill bits. Do not usewater.
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 minimise 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.
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 8 mm to 13 mm holes in steel can be made easier
if a pilot hole 4 mm to 5 mm is drilledfirst.
NOTE: When using a cutting lubricant, be sure not to get the
lubricant on thetool.
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

WARNING: Never drill into masonry which is reinforced
such as rebar reinforcedconcrete.

WARNING: For applications which produce a
considerable amount of dust such as core drilling, always
