smokeless cutting oil

[Chris12Participant @chris12]

What kind of system do you have to collect the coolant ? Just a basic tray, or something with higher edges ? A common complaint about the use of coolant is that it ends up everywhere.

 

Thinking about a proper coolant system now…

On Julie Ann Said:

As discussed above CT-90 acts a lubricant when tapping/reaming, often by hand. It is not intended for turning, which is why you didn’t see any difference. Cutting oils intended for machining are primarily used for lubrication where high cutting forces are involved; gear shaping for instance.

 

Just to clarify one things : I am not using CT-90 for turning. I’m am using Rock Oil cutting and tapping fluid, which is sold for cutting. But to my understanding now it is mainly for heavy (aka industrial) turning operations more than light duty cuts in a hobby machine shop.

Like Graham Meek, I have some Smith and Allan neatcut 32, I just dab it on with a brush as required, you can get it direct from Smith and Allan, or via their Ebay shop. It will smoke if you get it hot though.

I can’t give a comparison, as it’s the only one I have tried.

Mark.
