wards the quick-action drill chuck) so that the quick-action drill chuck turns clockwise.
Select left-handed rotation (arrow pointing away from the quick-action drill chuck) so
that the quick-action drill chuck turns counterclockwise. The right-handed/left-hand-

7. Place
• the drill bit straight on the marking.
• the bit straight into the screw slot or slots.
8. Observe the following notes on screwing and drilling:
Screwing • You can drive screws into soft wood without drilling a
hole in advance.
• Pre-drill when screwing into hard wood and driving in
large screws.
• Countersink the drill hole for counter-sunk screws.
• In case of wood screws without continuous threading,
pre-drill half a screw length.
• If the set torque is exceeded, the slip clutch will block
the rotation of the quick-action drill chuck.
Drilling (in general) • Pull the drill bit out of the drill hole regularly so that it
can cool off.
Drilling (wood) • Centre punchthe marking for the drill hole with a centre
punch.
• Place a wood block under it or drill from both sides to
prevent the wood from breaking off when breaking
through.
Drilling (metal) • Centre punchthe marking for the drill hole with a centre
punch.
• Clamp in the metal sheet and place a wooden block
under it to prevent deformation.
• Use an HSS spiral drill bit.
• Use a smaller drill bit to pre-drill the hole for a large bore
diameter.
• Use a lubricant for steel and aluminium;
Steel: oil
Aluminium: turpentine, paraffin
brass, copper, cast iron: do not use a lubricant
