They are dangerous if using it to cut and the wheel gets nipped. Had a couple of near misses.

Can't see them being banned, nothing else like them for cutting slabs,
concrete, etc. While they have a lot of "oomph" they are normally quite
heavy and the inertia makes them manageable.

Judging by the racket on a nice day around here most people have an angle

I think all power tools capable of making hot dust should come with eye
protection and a face mask of some kind.
People are stupid it is clear. A person I know has suffered for years with
getting tiny metal bits in his eye. The medics have done all they can but
its irritating and now they say they cannot do an mri of his shoulder in
case the bits of metal are affected by the magnetic field.

I bought mine for trimming bricks round an enlarged window opening. A 4"
one ain't deep enough to cut through a brick.

I'd say they're no more dangerous than a 4" one. Both need treating with

It's an obsolete spelling of angel. It originates because if you aren't

They are actually, lot more torque and a much bigger
spinning disk if it come apart when the disk jams in
what you are cutting. Much safer to use that disk in
a hand held circular saw if the disk come apart in use.

Both need treating with
respect.

Bought my first one in the early 70's; black and decker, it has done a
lot of work and is still fine. Might have had a couple of sets of
brushes. Still on its original power lead, with only one sticky
hot-shrink splice.

Even is face masks and eye protection are supplied the stupid will not
wear the PPE. Even if it's used the first time the tool is used the PPE
is unlikely to be stored with the tool and forgotten about the second
time it's used.

At some time in life people have got to take responsibility for their
own safety. The safety information is always included in the manual but
I guess most people don't RTFM. Possibly the problem is sometimes in
dumbed down safety advice in the manuals - part of an Amazon review I
wrote for a Dewalt Mitre saw "Truly awful instruction book. At the back
of the book is some safety related text but most of the manual is
pictures. The first page indicates you should be wearing a wet-suit, be
blindfolded and you should never plug the equipment into the mains nor
operate it if carrying a teddy bear."

Sometimes important safety information is lost in the pages of legal
arse covering...
Do not operate under the influence of alcohol or drugs
Do not operate this power tool in rain
etc.

Yup, this excess of advice for the retarded actually results in most people NOT reading even basic safety advice. It may be an improvement on the old days of zero safety information, but it's a mostly missed opportunity in safety terms.

Stupid advice is needed for legal reasons. Perhaps it could work a lot better if they put the stupid stuff & the sensible stuff in separate places.

Mind you I did see a deficiency in safety advice with one angle grinder. The instructions failed to point out that the machine should not be used for surgery.

The last bit was from a Makita tools I purchased recently. Some of the

Instead of just recommending safety glasses they must comply with ANSI

It appears that in Australia that it's a legal requirement to wear such
PPE when using this tool.

They are all much the same, my Metabo angle grider:

121 pages
pages 2€“3 picture with The Numbering of Parts
pages 4€“5 large table of specifications for every model variant
page 6 pictures with the reference Nrs of accessories

pages 15€“25 English instructions, of which
3 pages of safety instructions
2 pages how to use
the rest being blank space and yet more warnings

the rest of the big fat booklet being in every other language including
a set of pink pages with yet another page of safety instruction in English

It appears that in Australia that it's a legal requirement to wear such
PPE when using this tool.

I think the key is that the manufacturers do this to ensure they are not
prosecuted for 'dangerous equipment' and failing to inform its
purchasers how to use it.

Viz the apocryphal 'pet in a microwave' case where it was held that the
manufacturer was responsible for failing to inform users that it was not
suitable for drying out wet pets.

So it is less that these things are legal requirements on the *owners*
than that they are legal requirements on the *manufacturers*

There is no legal requirement for me as a private individual to wear
safety gear when chainsawing, and I don't.

But I could not employ someone else and make them perform without it.I
would be personally liable for any ****wittery they might indulge in and
no insurance would cover me.





As the TV advert asks "do you locks conform to bs3621 - no-one knows"!

So change them.

Mine oddly, all do.

Not that my insurance company has ever asked.

mechanical workshop.

I have the (relatively) new 1 mm sheet-metal-cutting disks. They are specced for
sheet metal of a mm or two, for cutting with less heat and less distortion than
the more usual cutting disks -- 5 mm thick or so? I am less inclined to trust
these, particularly if used in cutting thicker stock, as will inevitably happen.
(This lack of trust means I think more about where the bits would fly if it
should shatter, than when using a thick cutting disk. One should be checking if
the sparks are flying somewhere safe anyway, i.e. excluding tile, glass,
glasses, porcelain, ceramic, mirrors, etc from the landing zone. Most who have
used angle grinders have that particular t-shirt, is my guess.)

Any thoughts on the thin slitting disks?
