9" angle grinder with a diamond blade that is stuck on.

[Housemartin]

I have a 9" angle grinder with a diamond blade that is stuck on I have
tried WD40 and hitting the flange with a hammer and also a nail punch.
I have bent one angle grinder spanner trying to get it off, as have
tried hitting this and also using a extension pipe but to no avail,
any suggestions?

Have you considered the possibility the you are trying to undo the nut in
the wrong direction?

I had this happen once with a cheap grinder. We locked the clamping ring
in the vice and turned the whole grinder against it - which just broke the
locking pin... :o(

Have you got an SDS drill ? See if you can loosen the disk by
"drilling" onto the angle grinder spanner.
You could also try heating the thing carefully with a blow-torch and
see if differential
expansion will loosen it.

I'm not clear if the nut holding the disc is still in place?

I had the same thing happen when I wanted to change my 4 inch AG from
metal to stone cutter. I ended up using a mole grip on the wheel (It
didn't fracture that easily) to lock it in position and jam the mole
grip onto the guard, so that I could use a hammer to unscrew the nut
that held the wheel on. It was a bugger to undo though. Just run the
wheel, under power, and see if it revolves clockwise when viewed from
the nut side. If it does, then it has self tightened the nut.

If you're saying you can't undo the nut, I've had problems in the past
with the cheap spanners supplied by manufacturers. I did get one
particularly "stuck" nut off by using a pair of Robo-Grip pliers to hold
backnut and nut. Make sure you're turning the right way, and at the risk
of grandmother and eggs, you are using the spindle lock, aren't you?

My elderly Wicks takes an allen key in the centre of the spindle to hold
that against the normal peg spanner.
Surely all such fastenings are conventional right hand thread?

Hmm, all the ones I have had (B&D Pro and Bosch) have had a sindle lock
button that has to be held in and yes they should all be RH thread but
I've seen people tug the wrong way and sometimes the brain just fades
about which is the right way to turn.

I don't have a solution, but I certainly feel for your plight. I
bought a £50 9" grinder from Screwfix and the nut locked solid on the
first disc, I bent the spanner trying to get it off. So I took it back
and got a replacement which got through 2 discs before the same thing
happened. So that went back too and this time I got a refund.

I then got a £30 9" grinder from Argos and went through one disc, then
the second one locked solid. Got a replacement and the disc stripped
off the grinder leaving a permanently locked, unmovable nut. So that's
going back for a refund too.

I don't know if it's just that they are cheap grinders or if it's the
locking mechanism, which seems to be the same on all of them, that is
useless.

I have a Metabo grinder of this size. It has never had problems like
this, or in fact any problems, even with heavy use.

You've made two additional trips to Screwfix and three in total to
Argos by the time this is over, plus a further one to find something
new.

£50 for the original plus the cost in fuel and time for the
replacements is considerably more than if you had paid £100 at the
outset for something that works properly.

£40 for the original, no cost in fuel, no time for replacements - is
considerably less than if I had paid £100 at the outset. I have something
that works properly.

The mains switch failed on my Wickes one -- it got stuck ON.
Swapped for a new one, which I haven't needed to use much since.

Have a look at the 'AEG fixtec nut' (google), should solve the
problem.

Many thanks for all your answers I will be having another go tomorrow
and yes I was trying to turn it the right way using the spindle lock!

Strikes me you didn't tighten them properly - allowing the rotation to do
it for you.

I have a 9" Bosch where you need to turn the lock nut over as the
centring spigot is too deep for diamond or other thin cutting discs.

I have a different issue: where the spindle lock is damaged making life
difficult when changing discs:-(

Would you trust a disk that has been clamped in a vice?
10k RPM and damaged disks don't go together well.

If you're changing a diamond one chances are it's because it's worn out.

No:-)

Half the cost of the stolen one it replaced, though.

I think the lock was inadvertently operated while the m/c was in use.
Probably trying to get somewhere not really accessible.

Denting the thumb tip usually works.

Yes, always tighten them properly by hand first. If you allow the
rotation to do it for you, the nut "slams" tight and will show a
distinct tendency to jam.

This isn't a huge problem with £50 mangle grinders and consumable
blades (you can afford to be destructive, if you have to). On $500+
cabinet saws with £50 blades and more inertia involved, it's a real
problem.
