A thick cut-off disc can cause
unwanted burring, localised
heating and deformation when
cutting thin sheet metal and other
delicate materials such as profile
and tube of small cross section.
To avoid these problems, and the
possibility of having to rework or
scrap the job, Tyrolit, UK, has
added to its Secur Extra range a
0.75mm disc that is claimed to be
the thinnest on the market.
The resin-bonded, fibre-reinforced
disc is aimed at automotive repair
shops, electrical equipment fitters
and tinsmiths, but is also suitable
for heavier work such as cutting
steel rope and steel reinforcement.
The ultra-thin profile results in
straight, clean cuts and effortless operation,
making it particularly suitable for working
overhead. The load on the hand tool is also
reduced.
for strength and longevity, and may be used
at peripheral speeds up to 80m per second.
Tyrolit manufacturing operations are
recognised by the Organisation for the
Safety of Abrasives (oSa), and the 0.75mm
Secur Extra discs comply specifically with
EN 12413, ANSI B.7.1, and BGV D12.
