9.13 DRILLING WOOD AND PLASTIC –
FIG. 9
To prevent splitting around the drill holes on the
reverse side, clamp a piece of scrap timber
under the material to be drilled.
9.14 DRILLING METAL – FIG.10
Metals such as mild steel, aluminium and brass
may be drilled.
– Mark the point to be drilled with a centre
punch to help the drill bit tip to locate.
– A drop of oil on the drilled area will aid
cutting and help prolong the life of the bit.
Note: Although metal drilling is technically within
the capabilities of this drill, its rotational speed
is not always fast enough to achieve perfect
results every time. For this reason, extra
caution should always be taken when drilling
metal, as snagging of the drill may occur.
9.15 DRILLING MASONRY
Start drilling at a low speed to prevent the drill bit
from wandering. Once penetration is achieved, fully
depress the trigger to achieve maximum speed and
hammer power.
9.12 SCREWDRIVING
To prevent slip or damage to the screw head, match the screwdriver bit to the screw head size.
To remove screws:
– Move the direction switch to the reversing position and apply pressure to the screw head and
depress the trigger slowly).
Screwdriver bits are consumable items.
