Steel Cutting Lube
 
Iím drilling a lot of holes into metal (mild steel)
I have premium quality drill bits and are using lubricant (Suttons Metal Cutting Lubricant) , works a treat, but was wondering if there was a cheaper option than this expensive oil.
Any of you guys have an alternative?.... Is engine oil or ATF going to provide equivalent lubrication and cooling?....As a metalwork student in high school, i recall we used to make up what was called Ďsoluble oilí which was simply oil and water mixed.
Anyone got a new age formula for an inexpensive lubricant/coolant for cutting/drilling mild steel?
Thanks guys ✌️

Check your speed, too fast, too much force will dull a bit real quick. Let the bit do the work...

BTW: what's expensive, meaning price ?

I use marvels mystery oil for cutting, drilling, in the air tools, in my oil, and in my fuel.
Stuff is cheap enough and I always keep a bottle in the shop or have one in something I drive.

Marvel works well, I've used WD40 on aluminum. I have a buddy who owns a big machine shop and he lets me take a few bottles of water soluble coolant home, the mix is 50:1 so a little lasts me years.

https://en.wikipedia.org/wiki/Cutting_fluid may be helpful here...

https://www.amazon.com/Ounce-Bottle-...dp/B002R7VMEW/ is good for many metals such as aluminum, stainless steel etc...

Because it's so great or you don't cut much?

There are many good brands of cutting oil. I used the ACE hardware brand for hack saw and drilling.

After purchasing machines, now use Tap Magic. Cutting, drilling and taping, as mentioned WD is good for aluminum .

Metal bandsaws use a stick type lube, oil and rubber drive tires not a good combo.

Cutting oil, like motor oil a users choice and how much is it worth to the same.

Yes I have my preferences one size does not fit all. Because the different materials used for the tooling is also in play.

But without a doubt using cutting oil is the right way to go.

Thanks for the ongoing replies, the wiki article was interesting.
The last bottle in bought was Suttonís brand and was A$16.98 for 250ml bottle/ US$12 for 8oz, give or take
Obviously the small bottle is not a cost effective way to purchase.
Iím in Oz so some of the products mentioned are not necessarily available here and we have other ones.
I was wondering if someone had homemade recipe they found worked well.

This is what I use. https://www.acehardware.com/departme...CABEgKszfD_BwE

I am not kidding you, if this friggin can were to cost $50, I would buy it, THAT is how good this stuff works. I am not comparing it with others understand, I am not saying it's better than some other product. All I am saying is it's MIND BLOWING better than not using it! I use it with the hand hack saw, air saw, drills, and of course tapping, it's awesome stuff!

A 1/2 gallon of water soluble makes 25 gallons of coolant... that is a lot for my use.


I have a can of Tap Magic, works well. I also have Anchor Lube which can be thinned down, also Moly Dee for tapping harder materials.


My Bridgeport and lathe are set up with coolant pumps, I use the spray mist on the mill now and then.
