OPERATION TIPS
the bit out of the hole with the drill still spinning. This
will allow debris to leave the hole and relieve pressure.
When you press the bit back into the hole you should
notice increased cutting speed.
• When drilling metals you should keep a firm constant
pressure that ensures the drill bit is always cutting
through the material. If the drill bit is allowed to spin
without cutting then heat will build up and harden
the surface. Once hardened the material will be very
hard to cut and may damage the drill bit. Water or
oil continuously applied throughout the process to
dissipate heat will help maintain the cutting surfaces. The
increased leverage of a drill press/pillar drill can allow the
user to apply more pressure to the cut.
• Use a good quality sharp drill bit or hardened driver bit
with the correct profile as described below.
• Use sufficient pressure to ensure the drill is always
cutting material and back off that pressure to avoid
splintering the reverse side of your work and allowing the
drill to impact with the work piece.
• When doing big jobs that require constant charging of the
batteries remember that you can swap Li-Ion batteries at
any time during a charge/discharge cycle.
A 4.0Ah Lithium Ion POWER8 Battery will be charged to
80% of its full capacity in the first 30 minutes on the fast
charger, the final 20% capacity charges at a lower current.
Drill bits
There are 3 main
types of drill bit:
Metal (HSS)
, use
sufficient pressure
to ensure the drill bit
continues to cut
the surface, if it is turning without
cutting then the surface will heat up and become hardened
making it very hard to drill through. Support thin metals with
a wood backing to prevent distortion. Lubricate with oil to
keep bits cool, beware of fire risks.
Wood and plastics
(has an extra point on the tip),
regularly back the drill off to allow swarf (shavings) to clear
the hole.
Masonry
(has 2 spade head) a hammer drill will make fast
work of hard masonry and brick, a small pilot hole before
using a large drill bit is faster.
When drilling a tile use masking tape to mark the hole and
to prevent slipping, firm even pressure and patience will
give a good result. Lubricate
with water to reduce dust.
Driver Bits
The images on the right show both Phillips™
and Posidrive™ screw heads. These screw heads are
often confused. Look for the second cross shape on the
Posidrive™ screw head, for this type of screw use the
driver bit with 8 flutes. Posidrive™ uses PZ2, PZ3 etc.
Phillips™ driver bits are usually marked with PH2, PH3
etc and have 4 flutes. Higher numbers are for larger sizes.
When driving a screw in or
removing it, use very firm,
controlled pressure to ensure
the bit does not slip in the
screw head, damaging it.
Use the lowest torque
setting possible to drive
screws flush, this ensures
a consistent result and
avoids stripped screw heads.
• Mark your work and use a hole punch to guide
the drill bit or screw into the correct location.
• When drilling start the drill and allow it to reach
full speed before starting to cut. Maintain a
steady, even pressure and speed that does
not slow the rotation speed. Ease off slightly
whenever the cutting progress slows and lift
