Adapting grinder for wet cutting

[bsr]

Has anyone seen a wet cut adaptor for a 9" grinder? I've see the little bottle and hose jobs for stihl saws and wondered if you can get them for grinders?

Cheers

stihl saws are petrol so safer to use with water than electric, I wouldn't try it

Had to cut through a 15mm copper pipe that had a bit of water in it. Decided to use the 4 1/2" angle grinder with the diamond blade it it because of restricted access. A few seconds in and the grinder started wobbling violently.... only it wasn't the grinder doing it - it was me receiving the shock!

I think a grinder wheel at the cutting edge would travel far too fast to wet. It would always be dry. You would have to slow the blade considerably to get the right effect. Power tools are double insulated so electric shock isn't really a problem.

...electric shock isn't really a problem.

Famous last words?

Been using the things in the rain for years - the motor makes that much wind the rain doesn't even get close.

you need to think off that statement carefully

its caused by the air thats sucked in at one end being expelled at the other end
now it is possible the fan that sucks the air in will expell it away from the commutator and brushes but they are still live and contact with water may still cause eletricity to flow
double insulation means no more than 2 levels of insulation between you and the electrics so if one level fails the second will protect you but not from water

I mean I don't run in when it starts spotting with rain. I don't do it in heavy rain. However, you won't get a shock by cutting a wet pipe like someone suggested.

I'm afraid I disagree. Although water is a relatively poor conductor of electricity, it is still a conductor and you could receive a shock (even a fatal one) using a grinder in wet conditions.

 

[joe-90]

Don't do it then.

Here we go again - pratt Joe knows best. Suppose I imagined it then. You really are a fool.

 

[joe-90]

You are the one that cuts pipes full of water and gets an electric shock. What a fool you are.

 

[gcol]

I didn't think I got a shock - thought I was a liar.
It's one thing making and owning up to mistakes.... it's another thing entirely being a fool and a consistent one at that.
