FEATURES
BAND CLAMPS
These clamps are ideal for round, rectangular, or irregularly
shaped woodworking projects together with the range of
quality nylon, canvas, and rapid-acting band clamps.
SPECIALISED CLAMPS
In addition to traditional clamps, Pony Jorgensen also has
specialty clamps. The range of specialty clamps include the
hand screw, and hold-down clamps, cabinet claws, press
screws, gear, and edging clamps. All are available in their
option of sizes, materials and finish.
"If dust settles on the workpieces,
this is guaranteed to impair quality.
It has also been proven that
tools from which dust is actively
extracted have a significantly longer
service life."
SAW SAFETY
The SawStop Safety
innovation reduces injuries
caused by saws.  SAWSTOP SAFETY
Working with timber requires
the use of saws, which can
potentially cause injuries.
SawStop Safety is an
innovation that reduces
injuries caused by saws. Table
saws cause tens of thousands
of serious injuries every year.
SawStop minimises these
injuries by stopping the blade
within 5 milliseconds of
contact. That is ten times
faster than a car’s airbag. Ten
times faster than your reflexes
can respond to danger.
The blade carries a small electrical signal, which the
safety system continually monitors. When skin makes
contact on the blade, the signal changes because the
human body is conductive. The change to the signal
activates the safety system.
An aluminium brake springs into the spinning blade,
stopping it in less than 5 milliseconds! The blade’s angular
momentum drives it beneath the table, removing the risk of
subsequent contact and the power to the motor is
automatically shut off. Resetting the saw yourself is easy.
Simply replace the blade and affordable brake cartridge and
your saw is operational again. The entire reset process
takes less than five minutes.
DUST EXTRACTION
Whether cutting, sanding,
sawing or routing, dust is
produced as part of day-to-
day operations in workshops,
on construction sites and at
other mobile operating sites.
However, a dust-free working
environment is indispensable
in order to ensure that your
work produces good results. If
dust settles on the

been proven that tools from
which dust is actively
extracted have a significantly longer service life. When
working without dust extraction, tradespeople breathe in the
substances, some of which are hazardous. This poses a
health risk.

The Festool Dust Extractors keep the workplace safe and
healthy for all workers, offering numerous versions of
extraction systems providing the appropriate model in the
correct dust class for every user.
"Clean air and good working results go hand in hand. This is
why we offer numerous versions of extraction systems which
provide the appropriate model in the correct dust class for
every user. All Festool extractors have proven in independent
tests that they comply with legal requirements and are
manufactured according to the 'Made in Germany'
standards," explains Festool product manager Andreas Buck.
In addition, the extractors are suitable for use with Festool's
fully compatible system – whether for applications with power
tools, air tools or cleaning accessories.
Companies use different extractors to optimally remove dust,
depending on whether the work is being carried out on a
construction site or at a mobile operating site. The
Occupational Exposure Limits (OELs) for the machined
materials can be taken from the materials lists of the
occupational insurance associations. Each OEL value
determines the maximum dust concentration of certain types
of dust in the air. The benchmark is that the dust remaining in
the air must not pose a health risk, even when work is carried
out for up to eight hours each day.
Dust and dirt on construction sites are sucked in via the air
volume flow of the tool extractors. The extractor's turbine
creates a vacuum and therefore the air or volume flow
required for this. The air speed must be increased for sucking
in heavier materials. "Many people are unaware that the
suction power is not directly related to power consumption.
That's why you shouldn't pick a new extractor solely based
on the declared power consumption," explains Festool
Product Manager Andreas Buck.
A different air speed might be recommended – and therefore
a larger hose diameter – depending on the materials to be
collected: The larger the hose diameter, the lower the air
speed. The larger the hose cross section, the greater the
volume flow. For instance, lightweight materials, such as
wood, stone and glass dust, metal chips or PVC, only require
low air speeds up to 25 m/s with a large hose diameter. By
contrast, the best way to collect heavy materials, such as
oil or stony sand, is to use high air speeds with a small
hose diameter.
In addition to the filter performance, another important feature
of the mobile dust extractors is ease of transport on
construction sites and at mobile operating sites.
