irtgen SA has launched two
new cutting tools for cold re-
cyclers and soil stabilisers to
the South African market.
In cold recycling and soil stabilising, choosing
the right cutting tools alongside primary
machinery has a significant impact on both the
quality and cost efficiency of the application.
No two cutting bases are the same; sometimes
debris or large stones make soil stabilising
more challenging, or the base substrate
for rehabilitation is studded with abrasive
materials. This means that not only do the
cutting substrates differ significantly, but the
forces that act on the milling and mixing rotor
can also vary drastically as a result.
In an effort to further enhance its range
of cutting technology products and to cater
for the demands of particularly tough on-site
conditions, the Wirtgen Group has recently
developed two new cutting tools, namely the
Generation Z and the HT22.
“The Generation Z point-attack cutting
tools and the HT22 quick-change toolholder
system are a great combination offering long
tool life and offer a host of benefits to the
user, including high impact resistance, re-
duced wear and greater stability,” says Ian
Kukard, parts manager at Wirtgen SA.
The reshaped carbide tip of the Generation
Z point attack cutting tools has been further
reinforced and the quality of the carbide
material has been optimised further. These
improvements make the cutting tool more
robust and resistant to large blocks of stone
and abrasive materials.
The steel base, wear plate and clamping
sleeve have also been modified, making the
Generation Z components more durable.
Cutting tools with shank diameters of either
22 mm or 25 mm can be used with the Gener-
ation Z range, so users can adapt to different
requirements with ease and precision.
New development
The HT22 quick-change toolholder system is
a new development from the Wirtgen Group.
Due to the updated geometrical design of
the base and the upper and lower parts of
the toolholder, as well as the enhanced steel
quality, the system components are said to be
highly robust, offering the user sound stability.
The hammer head of the redesigned base
offers additional protection against wear.
“The direct benefit for the user is the ex-
tended service life of the cutters and the

Generation Z and HT22 are available for all
wheeled cold recyclers and soil stabilisers
in the WR series as well as tractor-towed
stabilisers in the WS series.
quick-change toolholder system. This results
in fewer tool changes, less downtime on ma-
chinery, longer service intervals and increased
machine availability, so soil can be stabilised
cost-effectively regardless of challenging
site conditions. Even severely damaged road
pavements can be recycled efficiently,” says
Kukard. “Wirtgen SA is proud to bring this
innovation to the South African market and
looks forward to passing on the many benefits
that come with Generation Z and HT22 to our
South African customers.”
