Thin discs in an angle grinder
Just got to report how fantastic ultra-thin cutting discs are in a 115mm angle grinder.
1.2mm thick, they go through box section and sheet stainless like a hot knife through butter. They are insurpassed for trimming.
A genuine contender for the title "The Tool"

Spacers
Yes you do need a spacer! the thread is normally long enough to allow very thin disc's.
Whatever you do - always where eye protection when using these wheels they are very susceptable to splitting. I know they flex, but I saw one bust as
an apprentice and I'll never forget it! If a fragment comes for your eye - your eyelid won't stand a chance of stopping it!

cutting wheel
to put your cutting wheel on your grinder without it spinning turn the locking nut the other way round and tighten with the spanner

I was demontrated the merits of one particular brand of slitting disc (can't remeber which brand sadly) by it having a large triangle chopped
out of the side of it and then being used to chop up a piece of 5mm steel, very impressive.

Personally Id be very wary of a thin disk. its easy to stress a disk when cutting, and a thin one had gotta be more fragile.
whats wrong with the normal 3mm type? they have a defined cutting line - A jigsaw or nibbler would remove at least 3mm of material anyway

Ummmm, they take an eternity and they're less accurate?

Gotta agree with the positive sentiments re thin blades.
Less waste material, and therefore dust!
Accurate cuts.
Just don't do what I did - try cutting an engine mounting with the engine unsupported (thought it was!!) - blade just exploded. Glad I was in
safety conceous mode (with googles!)

Thin ones are brilliant- is all I use now. Just can't see point of wider ones at all.
I use a 6mm for grinding and the 1.2mm for cutting- perfect combination.

I didn't discover these until I'd finished cutting all the steel for my chassis, with the wide disks - buggered one grinder and p*ssed off
my neighbours!

there seems no lack of speed on my 230mm grinder with a 3mm disk in it.
cut my outer door panels from stainless 3mm sheet with it on Saturday, no probs.
I need a new stock of disks, so I have bought 5 115mm jobbies to try from screwfix.

i just got my thin discs working today, shockingly easy! just glides thru stuff, so much better for the poor old dear next door! Its persuaded me to
keep on with the trailer project that i had abandoned due to noise considerations!

That's why we wear goggles.
I've been using some 115mm 0.8 blades for cutting sheet steel and they are brilliant. They don't snag as much as the thicker ones. As
quoted earlier, turn the securing nut over and they clamp tight. They are not suitable for 230mm grinders but do have the same centre hole size. The
larger gearbox gets in the way and you don't have the same fine control. For grinding welds down get some 40 grit flapwheels or emery disks on a
backing pad, not as vicious as grinding wheels and a nicer finish.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Brilliant if you use one of these from Screwfix and a 0.8mm blade - who needs a hacksaw!

that looks like it does compound angles as well! can it? i spent £200 at MM on a band saw, which admittedly is nice and quiet compared to a grinder,
but for the 180 quid difference the neighbours can go to hell with ringing ears!!

Yeah, we have one of those chopsaw adapters. May I just say though that the clamp on it is SHITE, plus due to the way it's set up you
can't cut any angle greater than about 30 degrees on it or the blade can't reach the base of the tube.
Still, worth having.

Yep, clamp could do with improvement! - but well "cheap as chips" and always being used

Bet we could make a better one - just can't be bothered at the moment.
Nice little project - could make it do all the mitre angles etc.

I cut all my chassis tubes with a hacksaw (yeah - one blade, and that wasn't even new), so saved even more!!
