Angle Grinders and the use thereof...

[Basil135]

So, here is the question.

When putting a cutting disk onto an angle grinder, which way do you face the label of the disk?

1) Label facing in (ie: facing up when looking at it from the top)

2) Label facing out

3) Doesn't matter...


I have asked 3 different people, and gotten the above answers.

cutting or grinding disk???, cutting eather way, grinding dome in

I'd say out, but don't think it matters. What i do know about them is don't get one stuck in your arm, they cut straight through your bicep and it hurts a little and makes a big mess:(

[101RRS]

They will cut you just as easily either way - right or wrong.

Nasty piece of kit as my thumb will attest. I sliced into the first joint on my thumb last July and it does not work very well any more - the thumb that is. Nearly did the same to my other thumb the other week - and that is with safety gloves on - cut through the safety gear like a knife through butter - got away with just a knick this time.

:eek::eek: This thread just pops up as I get news my mate down the road from here has done his thumb tendons and is in Dubbo hospital:(

The flange will matter but label I have my doubts. The problem here as most is incorrect use. Never work in a way that they thrust from the opposite side of a job and take you out:( The nine inch are nasty for this.

I here ya, i did my injury cutting inch thick lead plates on a battery bank in the ANZ bank basement, i was using a 5inch with a tungsten carbide cutting disc, was weraing all the safety gear, first cut and it jammed and bit then jumped up, grabbed my shirt and went straight in my arm through my bicep (58 stitches, half internal). This happened whilst i was a third year apprentice, i told the boss it was the wrong tool for the job, but hey what did i know:(, 'just do the job', they did the rest with a saber saw whilst i had a plastic surgeon fix my arm:mad:

the disc should have a metal flange on one side.....
this should face whatever it is that centres the disc on that particular grinder.....

on most of the standard 4 inch little home grinders......its the nut that cetres the disc.....
so the metal and in most cases this is also the label side.....will face the nut.....

some of the discs actually have a picture and instruction as to which side should face the spindle.......

[Slunnie]

Facing in so that you can see it when you're operating the machine. I tend to think that its more just good practice as its consistent with grinders and flap discs.

[Basil135]

I have the utmost respect for angle grinders...

I too know of people that have caused themselves serious injury with them.

I am quite happy with my little 100mm thanks.

[Blknight.aus]

what zook said plus the label is usually on the up side of the flange...

try to mount a flap, grind or wood disk upside down and you physically cant do it because of the guard.


ummm

you do have the guard on right?

[Basil135]

ummm

I always have the guard on. There is a reason that I don't borrow my mates 9" grinder - NO GUARD :o:mad:

[BigJon]

Label up for me. I also use the thin 1 mm discs. They don't last as long, but they do a neater job in my opinion.
My 100 mm cheapy grinder has a locating shoulder on the grinder shaft. The nut can go on either way, one way is flat sided for thin discs, the other way has a locating shoulder for thick discs.

[Redback]

Most of the discs I've used, there isn't a label on the grinding surface of a grinding disc and on cutting discs the same.

Self explainatory.

Technically, the cutting surface of a cutting disc is the edge of the circumference. Bit hard to get a label on there!

[Tombie]

The 'kick' on a 9" grinder has some much 'damage' potential that they are banned on all work sites up here...

Max is 8" and must have instant braking

Yeah that's what I was thinking when I clicked. On most cutting disks I have bought the label is on the same side as the flange. But then I also bought a bunch of cheap Chinese ones that had no labels.

You would not get an argument from me about this ban. I regard those 9" grinders as just about the most dangerous hand held tool of all.

Why is it that the most dangerous tools are also regarded as the simplest and operated by unskilled, untrained labour? Chainsaws, 9" grinders, aerial loppers to mention a few.

AFAIK the label is supposed to go on the side away from the grinder as some sort of 'containment measure' in the event of catastrophic failure of the disc.

Never had that happen though. :D Well, maybe once or twice.

Never really thought about it much until I read a similar thread on some other forum a couple of years ago and someone chimed in with that info, and labels then were generally paper.

Cutting discs generally are not directional i.e. you can put them on either way. If they were directional there would be an arrow on the label to indicate which way they should rotate. On this basis it doesn't matter which way they are mounted, label in/label out. The label is only there to provide information eg. barcode, size, use etc.

Grinding disks are generally dished and can only be installed one way around or they will interfere with the guard.

Just an aside. (In my opinion) Angle grinders should always be used 2 handed (for safety) clamp the job down correctly and you lessen the risk of damage to yourself.
