Thread: What type of coolant do you use?

I haven't heard of it, but the blue stuff Ray uses on his grinder sounds good as you can see through it. I am going to look into it up this way when I need some more.

Hi Simon,

I've been lately using a 50-50 mix of lanox and kerosene, I think kersosene is similar to white spirit?

The water based coolant Dave referred to is Fuchs Eco-cool, and I use that on the grinder, but it's pretty good as a water based rust preventative as well, so I have a mix of eco-cool and detergent that is handy for cleaning off oil.

Straight metho makes a good coolant as well, especially for aluminium.

Regards
Ray

Hi Simon,
Coolant for what?
It doesnt sound all that cheap, unless you're just talking about making up a couple of litres.

I think it's for his new mill/stand set up.

I'd be a little worried on a mill of anything with motor oil in it. I tend to get coolant all over the place when I use it, which is bad enough at 20:1. 60% motor oil would seem to get messy quick.........but hey it could be worth a shot.

Hi,
I use lube alloy oil. I find it ok, but see through oil would be good. Any chips I leave on the mill do tend to rust though, but not the mill itself.

I have been using Callington Ultra Synthet 971, that is what my supplier has stocked. I use it at 5% concentration mixed with water. It seems to work well, has rust inhibitors (so no rusty swarf or machines), is non-carcinogenic and does not stink up over time. I use it on the lathe and mill and also with the bandsaw and hacksaw.

Hi,

I'm using kero and compressor oil at the moment (from a spray bottle), works fine.

I did score a litre of real coolant from work awhile ago. Just oil which you mix with water. Can't remember the brand, but is commercial/industrial type.
