Drilling Tools
The machine is intended for hammerdrilling in concrete, brick and stone. It is also
suitable for drilling without impact in wood, metal, ceramic and plastic. Machines with
electronic control and right/left rotation are also suitable for screw driving and thread
cutting.
Chipping Tools
The machine is intended for chipping in concrete, brick and stone.
Drilling
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.
1. Always unplug the drill when attaching or changing bits or accessories.
2. 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 carbide-tipped bits
rated for percussion drilling. Be sure the material to be drilled is anchored or
clamped firmly. If drilling thin material, use a wood “back-up” block to prevent
damage to the material.
3. 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.
4. Hold tool firmly to control the twisting action of the drill.
5.
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 AT TEMPT TO
START A STALLED DRILL — THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce pressure on drill and
ease the bit through the last fractional part of the hole.
7. Keep the motor running when pulling the bit back out of a drilled hole. This will
help prevent jamming.
8. 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.
Removable SDS Chuck & Three Jaw Keyless Chuck
(D25114-XE, D25314-XE)
The D25114-XE and D25314-XE are equipped with a removable quick change SDS
chuck as well as a removable three jaw keyless chuck. The hammer mechanism
does not function when the three jaw keyless chuck is used.
Both the SDS and three jaw keyless chuck can be easily removed by turning the collar
(K) into the unlocked position (L) to release the chuck (Fig. 6).
The SDS and three jaw keyless chuck can be easily attached by inserting the chuck
into the spindle of the tool and turning the collar to the locked position (M). The chuck
will click when properly installed.
DRILLING IN METAL
(D25113-XE, D25114-XE, D25213-XE, D25313-XE, D25314-XE)
An SDS to round shank adaptor chuck is required. Ensure that tool is in drill-only
mode. 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. The cutting lubricants that work best are sulphu-
rized cutting oil or lard oil; bacon-grease will also serve the purpose.
NOTE: Large [7.9 mm to 12.7 mm (5/16" to 1/2") ] holes in steel can be made easier
if a pilot hole [4 mm to 4.8 mm (5/32" to 3/16") ] is drilled first.
DRILLING IN WOOD
(D25113-XE, D25114-XE, D25213-XE, D25313-XE, D25314-XE)
An SDS to round shank adaptor chuck is required. Ensure that tool is in drill-only
mode. 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. For larger holes, use spade bits, power auger bits, or hole saws. Work that is
apt to splinter should be backed up with a block of wood.
