Operation
Tips and notes on handling the cordless rotary hammer
General information:
•
The centre position of the clockwise/counter-clockwise
rotation switch (lock) is suited for work breaks or (drill) bit
exchange.
Drilling in general:
•
Take short breaks regularly during drilling. When doing so,
take the drill bit out of the drill hole so that the drill bit can
cool down.
•
Secure the workpiece in a tensioning device or vice.
•
Select the speed depending on the material characteristics
and the size of the drill bit:
– High speed for small drilling diameter or soft material
– Low speed for large drilling diameter or hard material
•
Use a suitable aid to mark the intended location of the drill
hole.
•
Select a low speed for spudding.
Drilling in metal:
•
Use suitable metal drill bits (e.g. drill bits made of
high-
speed steel
(HSS)).
•
For larger drilling diameters, use a smaller drill bit for pre-
drilling.
•
To achieve ideal results, the drill bit should be cooled with
a suitable lubricant.
•
Metal drill bits may also be used for drilling in plastic.
Drilling in wood:
•
Use drill bits suitable for wood.
•
Place a block of wood under the workpiece or drill in from
both sides so that the wood cannot break off when it is
being drilled through.
•
Use a wood drill bit with centring tip. For deep drill holes,
use an auger bit; for large drilling diameters, use a
Forstner bit.
Hammer drilling in masonry / bricks:
•
Use a drill bit suitable for masonry / bricks.
Screwing:
•
When using screwdriver bits, always use a universal bit
holder. Only use screwdriver bits that are suitable for the
screw head.
