Installing and Releasing a Bit
Open the keyed chuck jaws by turning the collar by hand,
10
then insert the shank of the bit about 19 mm into chuck.
Tighten the chuck collar by hand. Place chuck key
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.

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.

Drilling

e
Drilling in Metal
13 and fasteners for 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
WALT Tool Tag,

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: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
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.
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
