Title: What an angle grinder can do (NWS)
Post by: mantahatch on 21 August 2013, 07:45:07
Don't look at picture if squeamish etc


This what happens when you take your goggles off whilst angle grinder is still spinning and the strap from the goggles is caught by the rotating blade.
This is a chap who I work with sometimes, thankfully not very often  ::)

Tbh, it doesn't look too serious (if a little painful) I cannot see any tissue damage just the full thickness skin lesion which, once debrided and stitched, should be ok.  He won't be doing much with that hand for several weeks though, it may well have to be immobilised slightly to ensure the stitches stay in tact.

The subject is very lucky.  There is an artery which passes very close to the wound area and that could have been pretty messy.

Nasty, but I think most people underestimate how much inertia a disc cutter has after the power is turned off. You should NEVER put a disc cutter down until the disc has stopped turning.  :o :o :o :o

If I'm cutting bricks or blocks and feeling impatient then I will use an offcut to slow the disc down quicker and this also shows how much inertia there is.  ::)

You'd never catch me doing something like that  :-[ (Or stopping a drill with my hand on the chuck .. that would be silly!)  :-[

Familiarity breeds contempt and all that..

Also to keep a proper hold of them when starting them. My Makita 8"/10" ( :-\) grinder kicked as I started it and caught my shin .......  ??? Very fortunately it just cut a hole in my overalls & made the tiniest mark on my leg, I considered myself very lucky. :y

I use a battery 12v drill and have to admit to holding the chuck to fit and remove bits all the time  :( Think I may have to rethink my attitude to such things.

I used to work with a bloke who had a massive scar that ran right up his chest and across his shoulder.  A 9" angle grinder kicked back when he started it, he wasn't holding it properly and it gouged it's way up his front and just missed his neck!!  :o  :(

Some years ago, BT introduced an (official) ban on people borrowing power tools from Engineers - who were quite well equipped for external works.

Eventually it leaked out that the reason was that someone had borrowed a chainsaw & substantial ladder to work on a big tree in his  garden. He was an in-experienced chainsaw user.

It was alleged that there was the sound of three heavy objects hitting the ground. None of the objects was wood, one of them was the chainsaw - think about it  :o

Seeing how easy angle grinders shear through metal that doesn't look too bad..... lucky to still have a hand i'd say!

some years ago our farm fitter cut a piece of steel with a disc cutter, and then proceeded to pick up one of the cut ends without deburring first, not a particually wise move, as his next stop was the local minor injuries unit !

For several years I worked in a fettling shop grinding & cutting cast iron.Sparks in the eyes was an occupational hazard,and could never be completely stopped no matter what ppe was used. I suspect that may have been a contributory factor in me needing glasses quite early.
Our manager bought a load of old equipment from a company which was closing down.These were what he called "hi cycle" grinders.
They were old and worn out,but scarily powerful.One day my workmate was using a 9 " version and the guard slipped off the body of the grinder,due to wear on the body,so the clamp wasn't effective.The guard and disc hit him so hard it knocked him off his feet,breaking several ribs and making a very nasty hole on his arm.He had about 6 weeks off work and enough of a claim to pay off hos mortage.
Those were the days. ::)

Never needed medical treatment for it but I have, once upon a time, picked up a piece of offcut immediately after chopping it off. Ooh it was hot..

I also managed to stick my hand on the end of a piece of studding that I'd just ground down, too. I even thought, right before it, "Better not stick my hand on that"..

Still, it could be worse, there was the time 2woody set fire to the Jag in my garage with the plasma cutter... ;D ;D (OK, that was more comical than anything else)

I sliced my fingers open on a make shift tin oil can that had the side cut out to drain oil into , luckily next door was a sexy nurse that took me to A&E  :-*

Always have a fear of tin cans now  :-[
