Machinist's Minutes: Cutting oils and coolants

[@HOWEES]

The barrels of high sulfur oil, were bought from "Industry Depot" in 2015, sorry I can't find a current link or ph# for them. The other option that I had found at that time was the Hercules dark cutting oil, available from many sources in gallon jugs.

Im a student currentley going to school for tool and die and i will say being in an area where all the shops are going completely cnc these videos are fantastic for learning old school ways of machining they dont really teach by me anymore

So what's your suggestion

[@jimwednt1229]

You're a good man taking the time to mentor us. Sharing the knowledge you've aquired over the years, with the youth is an invaluable education and a process that needs to be brought back across all disciplines. Thank you . Most kids nowadays don't have the access to elders who want to mentor them . Not as many around as a century ago. The breakdown of the family and proliferation of immorality in society.is the cause. I'm sure you know that .

On aluminum, isopropyl alcohol works fantastically well. Used with a cheap mister, it evaporates before it puddles up, less mess.

[@b.paddenmaintenanceandrepa2872]

I am excited for the lineboring! I was stumped on building the boring bar, what steel to use, and drilling the holes perfectly! There is not a lot of info on homemade set ups. Im a truck mechanic, not a machinist, however with you own businessyou do it all. You guys are helping me branch out with a practical can do additude love the videos keep them coming!

[@jalenwalshak3598]

I recently installed a wet line tank on my peterbilt and used the vevor mag drill and the bits that came with it and I was very impressed with it. I used cutting oil also and it helped too. Love watching your videos. Learn something new everyday. My grandpa always said if you don’t learn something everyday your not doing it right

[@donavinnezar]

as a neat cutting oil i use one from fuchs , its a yellowish colour and it definitely has sulphur innit , i can smell it , smells like a rotten egg when i open the can to refill my oilcan , i have used some of the tapmatic trichloro ethylene based lube , i was tapping a m45 with a pitch of 5mm , this stuff really does wonders , boss didnt buy more and we had to do more of those big threads but used undiluted water soluble oil instead and ended up breaking the tapping wrench and needing 2 people to work together to actually turn the tap

[@jeffreyjohnston1625]

Affordable line boring for the small shop and limited machine tools will be a good series.... We have a Milwaukee mag drill with annular cutter morse taper adapter .....Thanks for sharing your life time of experience and imformation !!

[@rok1475]

I started using ordinary canola oil for cutting. It is not healthy for human consumption, but environmentally friendly and seems to work for me in machining. It is inexpensive and when it smokes it smells like food fryer. Thanks to all the additives it never goes rancid and nothing grows on it. Built up cleans off easily with isopropyl alcohol or detergents, doesn’t interfere with welding. Worth trying.

[@EddSjo]

Who told you canola oil isn't healthy for humans?

If my comment make you think that I am just another food fanatic - ignore it. If it makes you think that maybe there is something to it - look it up, the information is out there. But please don’t expect a lecture here on the history of “vegetable oils”, how they are made, what they contain and what possible health effects could they have when consumed over lifetime. Food for thought- it took a while for the society to accept that cigarettes are not as healthy as doctors, who recommended them to pregnant women to calm them down, once thought. Sugar is very slowly getting recognized as dangerous to our health in the quantities we consume (on average). I hope one day “vegetable oils” will join the list. Until then I will be making those unsubstantiated comments about them but you are free to not think about it at all.

At the shop where i work, we have huge Gantry mills, about 5 meters by 8 meters table size. The mills and the parts we make on them are physically to big for liquid cooling, it'd get stuck in small cavities, cause rust, fires, and smell up the place. So they are cooled exclusively with compressed air, cutting both easy cutting stuff, like cast, but also tool steels and things of that nature. The only cutting fluid they use is dark cutting oil, they have it in watering cans like you use in a garden, they only use it when drilling deep holes into castings

[@MWL4466]

The company i work for purchased a Climax portable lineboring system about a year ago. Nice machine. Paid for itself in no time. I operate a horizontal boring mill and had an 8 foot boring bar made up with square holes every 7 inches apart to hold a cutter. We bought some pillow block bearings and made up some other supports out of angle iron. Now i can line bore nicely . You're right. You can spend many thousands or get a little creative and come up with something just fine. Sometimes theres money in a job to justify the expense. And sometimes business is slow and you can experiment a little. Cheers from Canada.

[@Vikingwerk]

I’ve been using air tool oil as cutting oil drilling holes lately because it was within reach. It actually works pretty well! Way better than the 10w-40 motor oil that usually gets used around here….

[@bcc2a]

Boelube blue wax applied with a flux brush does amazingly well on annular cutters. Speed control is critical when you get into larger diameter bits. I think I run 1" at around 350rpm

[@georgewelker853]

There was a cutting grease that was popular in my area called coolcut it was perfect for odd stuff and occasional needs it came in a tube like grease but turned into a liquid as it heated up

[@dcraft1234]

I've been experimenting with EP gear oil for tapping. I'm not sure if it is sulfur heavy, but it sure smells like it and works great in steel.

[@northmanlogging2769]

old formula Tap Magic with the trichoroetheline, was the skookum choocher, it was fine and dandy unless you tried it on aluminum... then noxious fume city... (I'm now concerned for my liver...) Castrol Molly DEE is pretty skookum on anything but copper alloys, still works good but stains the copper stuff

[@NTK_FabWorks]

I’ve been using Zep Lubeze Drill Chill for going on 14 years, it’s some incredible stuff. I’ve always hated how it smelled, but never knew about sulfur and chlorine. Just looked up the sds and sure enough, it has sulfur in it. It’s also really thin and creeps in when using it. It’s around $200 for 12 16oz cans, just found a place selling 5 gallon pails for $200, where other places are $350+. I don’t need it right now, but 100% buying it before it’s not available.

Take a look at Ridgid or Oatey pipe thread cutting oil.

[@servicetrucker5564]

If you are tapping hard and wear resistant materials, like Hardox or acid proof steel, this make's our day so much easier: 400 G ROCOL RTD LIQUID R53072. There is greasier version of this.

[@moosesmachinery]

Ive gone to using mineral lard oil for most everything that requires cutting oil. Works great for the price ($20/a gal or so) and doesnt offend the nose too badly. Its not the best, but it works great and isnt too terribly toxic.

[@garth849]

That's what we used back in the day. Works well, but when it goes rancid you'll know! I don't think the lard itself ever really goes bad, much like tallow its pretty stable, but other things like bacteria can find a home there and get quite comfortable.

[@moosesmachinery]

Thank You for sharing Your Experiences!! They are super helpful! I'm just getting into Metalworks, both traditional and machinig and I wondered for a while now, would vegetable Oils work also as Lubricant and Coolant?

[@benpeterson9835]

These cutters are designed to be used with flood coolant . Lower rpm helps regardless

Try the blue boelube in the tubs instead of the white sticks. I like it much better.

[@dr.feelgood2358]

Beoing Lube...I just realized that is what our machinist at work has been using for tapping 316 stainless. it really stays in the threads, so I have to heat it to get it to flow out, because if I don't it smokes like crazy when i weld around it!

[@markferrari9734]

Ball Tap "S" is a great cutting oil. Smells like deviled eggs mixed with a draft beer fart, but works great on everything and doesnt stain aluminum like a couple that ive tried.

[@AndrewHemstreet]

Would your quick mention of diesel fuel perhaps only apply to the days before ultra low sulfur is all that's available?

[@waldemarii]

I have found out that WD40 is the best with aluminium. I have tested many other products, but WD40 comes on top always. WD40 Specialist Multipurpose Cutting Oil works very well with steel. All I use are these two.

[@swgard1]

Rapid tap or cool tool II works very well to drill aluminum for me, we have some water based castrol cutting fluid that we use out of misters on manual mills, airs great when you can get away with it

When I was a kid, I was given kerosene to use with aluminum.

[@lpfreak1708]

Can't wait to see the line boring with the mag drill!!

[@endoresu]

What about motor oil or vactra way oil? That's what I usually use when hand drilling and tapping.

[@jenpsakiscousin4589]

We went with the micro lube or accu-lube system for a while, on mag and aluminum it wasn’t much better than an air blast and it made everything sticky.

[@UbrShadow]

So as a question out of curiosity. What is the difference between cutting oils and honing oils? Furthermore has the need for lapping become something that is far more specialized?

[@rok1475]

„The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.” So the lapping oil/fluid/compound is in fact a liquid or paste abrasive that grinds the surface. There is no cutter involved in lapping operation, the tools used for lapping push the abrasive suspended in the carrier substance to remove material. The cutting oil on the other hand is a lubricant that reduces friction between the cutter and the workpiece.

[@Nilhilustfrederi]

maybe mixing in elemental sulfur would work, it's easy to find.

[@phalanyx3478]

Has anybody else here ever had a lung rupture in this trade or in mechanics? My lungs are feeling real fucked up 2 years in using zep drill chill which is heavily chlorinated. Before machining I worked stucco & cement, absolutely no lung problems even without a respirator when mixing mortar/cement/basecoat. Before that I was an apprentice auto mechanic; 2 lung ruptures. Mechanics use a LOT of chlorinated brake cleaner and so did my shop. I'm only 22 and have had 3 spontaneous pneumothoraces and the only things they all had in common was the chlorinated chemicals.

[@NTK_FabWorks]

I’ll second the stench of drill chill. I’ve always hated the smell of it and the smoke it creates, always try and set up a fan or ventilation when possible. But I’ll be damned if that shit isn’t an amazing cutting oil!

[@phalanyx3478]

@@NTK_FabWorks Its an amazing oil, Ive drilled pilotless 2.5" holes a foot deep in 4340 with it and a HSS taper drill, but that shit reeks and gives me a smoker cough. Its even worse to inhale after blowing the stuff out of a tapped hole.

Seriously, don’t use anything with 1.1.1. I had a 55 gallon drum of that when we were processing Kodachrome film. It was used right before the film dry cabinet on rollers that looked like paint rollers to remove the residue cyan dye. Whenever I went on the processor platform I would get a tremendous headache. I never figured out which chemical it was coming from. Then the EPA banned it and I had to get it disposed of (properly). My headaches went away. This chemical will not only kill your liver, but it’s cancerous. It’s a very serious danger to health. Never use anything that has it. Fortunately, you can’t buy anything new with it. The fact is that 1.1.1. Is slightly better for cutting, but really, it’s not that much better. Just stay away from it.

[@phitsf5475]

Engine oils are designed to keep metals from touching each other, not a good thing when you're trying to cut.

[@warwickms_teched2907]

I had the same experience with Clear CRC cutting lube. Bought it for a job, was very disappointed in the performance, and it is sticky and doesn't clean up nicely. WD-40 or Tap Magic Aluminum for aluminum, and dark cutting oil for steel. I do want to try AnchorLube at some point.

[@RichieRichOverdrive]

I have a small bottle of green anchorlube, it is ok. I mostly save it for drilling and tapping in stainless. It’s nice that it’s sort of a paste and you can dab it on wherever and it sticks there, at least until it gets fairly hot, at which point it gets runny.
