Cutting oil

[Fretters]

While cheap, they aren't quite what I have in mind. I may have to hit a hobby shop for valves used in RC airplanes, or a good pet store that has brass valves for aquariums. I really would prefer brass in this situation.

Look for old air, fuel or gas taps. Fuel petcocks are another option too, from the likes of motorbike fuel tanks.

Anchorlube G-771 is a green lube that is the consistency of pudding that works very well for drilling and cutting in general. It is environmentally friendly as it contains no oil. You can get a free sample from thier website http://www.anchorlube.com/

Another good oil is Ultra Lube Metal Cutting Lubricant, Fastenal #0301864. it is the consistency of honey and will not smoke, but metal chips stick to it and it's kind of hard to remove from the surface.

Is kroon olie duur?

= "Is kroon oil expensive ?"

Hi Seinmetz, I paid something like 6 euro ($8,34) for a 500 ml (~0,132 gallons) bottle. Not really for free, but when using a small brush to add the oil you can do a long time with it. I think it's worth the money.

The shops Ive worked at use tap magic and Mike-o-cut tap magic I use mainly at home..Mike-o-cut is the best for when trying to get that one last hole out of a tap or drill..but sticky and messy..probably really only needed in machine shop..using some kind of fluid will really make a difference in tool life and make nicer holes/threads.. A can of tap magic that will last a long time for the avg person can be had for under 10 bucks

Isn't Fuchs an American producer? They do cutting fluids too. Have a bottle of theirs stuck on a shelf somewhere. Claggy brown stuff it is.

I need a new can of Tap Magic or Rapid tap mostly used fo0r threading and occasionally for drill or holesaw. Most steel I do by hand and dry. My helper uses a drill press on occasion but I cant remember the last time I did. I like vise or clamp to the bench, so easy to flip pieces around.
I am not much of a machinist and beat the snot out of bits but,,,, its fast, its super simple, portable.

I was recent on a job with ironworkers. They were drilling some holes in the bridge steel & were spraying Windex on the bit. I kinda chuckled and said "no cutting oil, huh?" He swore that it worked better than oil & that a lot of ironworkers use it

I wonder if his wife was at home cleaning the windows with tapmagic?

Windex is only a low conc ammonia solution. You'd think straight water would work just as well to cool it.

BTW. Last time I looked at buying cutting fluid around here they wanted $17.50 for 250 mL http://www.bunnings.com.au/sutton-250ml-cutting-fluid_p6320395

Hmm, used ATF and with a dash of kerosene costs me close to nothing and seems to work just fine.

Humm. Not long ago I posted an question about the use of lard. I kinda got flamed for it. Boiled down to why use it with so many new high tech products out there.

I was basically interested in the history of the use of lard. Whatever.

I have also asked about the use of hydraulic fluid (I had 5 gallons that was contaminated with water and wouldn't trust it for use as hydraulic fluid) and was informed that it would not be a good cutting fluid as there was not enough sulfur in it. I thought HF and ATF were close relatives. Maybe not.

When sharpening a knife on a stone, use of water or oil "floats" the swarf away preventing the swarf from cloging the poors of the stone. Wouldn't this also be the case in drilling or cutting?
