Do you trust WD40 to be a lube then? I am very wary of it, When drilling which is about all the machining I do, I'll use 3in1. I think the difference is that ATF for instance is a fantastic lubricant but does it have the qualities needed when cutting metal?
Could start a whole thread on this!
PS I feckin hate working with stainless particularly due to its propensity to work harden in nothing flat and then eat drilling bits.
Found this which is quite interesting,
https://www.thomasnet.com/articles/process-equipment/cutting-fluids-for-machining/#:~:text=For tool steels and tough,mineral-fatty oil is used.

and discovered that WD do make a cutting lubricant!

I have been using standard WD40 for cutting aluminium and mild steel for as long as I can remember. The Rocol is for tapping and heavier cuts / harder materials. I have not used 3 in 1 as a cutting oil but I will give it a go. I am always will to try stuff as no one can know it all :)

+1 Me too!
All a drillbit is looking for really is some cooling.
Ali Loves WD40 when being turned.
Steel, I am using "proper" cutting oil. But I am a noob at turning metal.

I wouldn't take anything I say as being a good idea! I am not a trained engineer and tend to just use what I have lying around.
In the days before the internet I used to buy old skool engineering books and take advice from them. They were interesting and had recipes for making stuff you could never make nowadays as the ingredients are now illegal to buy/sell!
When I visited the Enots factory that made the stuff I flogged as a rep, they worked brass and ally on computerised lathes, churning out fittings, valves etc at a very fast rate. They were very proud of the cleanliness of their swarf which they were able to sell for quite a sum. They used continuous flow cutting fluid that was a kind of milky brown, but then I hardly ever drill brass and at the time I wasn't interested enough to ask what it was.
Ally I find needs little lube, but then I usually only drill thin sections.
I also use 3in1 when hacksawing, for what it's worth!:)

That is the flood coolant I mentioned. It is a water soluble oil (I know but yes it does exist!!) and requires care as it can breed bacteria that can cause all sorts of problems. I suffer from contact dermatitis and cannot risk it (I used it extensively in my youth which is what caused the problems with my skin).
I have many years experience but I will still listen to other methods as you never know what can help :)
 
Me screwdfix order be still not ready. Gorra message this mornin sayin it be send oat ware ouse to the chop. Wait fer massage ter say it be there. Int gorrit yet.

That makes sense, and in that link I put up it mentions many lubricants that are very water soluble.
Such a shame about the dermatitis.
No elf n safety in them days.
To think that nowadays you so rarely see a mechanic NOT wearing gloves.
In my yoof I used to coat my hands in washing up liquid, rubbing it right in until it was dry. It worked a treat as then any oil I had on my hands washed off easily, but it didn't work if I was dealing with coolant.:rolleyes:
I used to use barrier cream, but now like most, I use tough gloves which are a lot better than they used to be. Frinstance I only used two pairs all yesterday. :)
