9. BASIC HAMMER DRILL OPERATIONS
13
9.6 SDS+ SYSTEM – FIGS. 10 – 11
The tool holder clamps SDS+ drill bits and chisels
without the need for a chuck key.
– Pull collar back.
– Insert the bit. It may be necessary to rotate the bit to
ensure it engages correctly.
– Release the collar to lock the bit in place. Check by
pulling the bit to see if it's firmly seated.
IMPORTANT: Always clean and lightly grease the tool
shaft before inserting into the chuck.
Take care that the dust protection cap is not damaged.
Allowing dust and debris inside the holder will cause
problems in the future.
– To remove a bit, slide the collar to the rear and
pull out the tool.
WARNING: Bit will be hot after use.
9.7 DUST AND SWARF:
A correctly fitted dusk mask, suitable for the activity and
in accordance to the relevant standard, must be worn.
For work activities involving exposure to fine wood dust,
a mask rated to at least FFP2 should be used.
Swarf produced by metal drilling is extremely sharp. Take
precautions when clearing swarf. The burr left on the
hole is also sharp and should be removed with a
suitable tool.
9.8 DRILLING WOOD AND PLASTIC
(as per section 9.2, page 12) – FIG. 12
To prevent splitting around the drill holes on the reverse
side, place a piece of scrap timber under the material
to be drilled.
9.9 DRILLING METAL
(as per section 9.2, page 12) – FIG. 13
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.
