They used to be a True Value Hardware. I'm not sure if they are part of a chain
now. I don't buy
much from them as their prices aren't low. The gallon of Carb-Sol weighs 13+
lbs. It's hazard class
6.1 as per DOT. This might be you best bet. The where to buy page from Sunnyside
If you really like the stuff, you might want to go back & grab some
more. From the Sunnyside site:
"Where can I buy Carbo-Sol?
Carbo-Sol was discontinued in January, 2006 because of changes in air
pollution regulations in California and other states. ..."

I am unable to post to RCM due to a problem with my ISP. I can
read, just not post.
You have it wrong. Trichloroethylene is not the solvent used
for machining. What you're thinking of is 1,1,1,
trichloroethane-----which was the active ingredient in Tap Magic
and other tapping solutions at one time. They were NOT
recommended for aluminum, nor should they be used on aluminum. It
requires a different formulation to avoid corrosion.
I am very familiar with the use of the chloroethane I mentioned.
It used to be used in the sumps of our turret lathes along with
cutting oil when I worked at Sperry.
Thought you might like to know.
Wikipedia does mention rubbing alcohol (isopropyl) as an aluminum
I don't endorse using wiki as a be-all and end-all source, but it is
useful for turning up tidbits to be fleshed out via more reliable
One shop I worked in used denatured in a spray bottle for 1/4" and
smaller endmills cutting pockets with carbide.
For cooling though, not cutting. Spray misters created too much local
Another benefit is chip clearing - no sticky coolant holding the chips.
my 2 cents
Thanks for all the responses.
I was mainly interested in the alleged claim that alcohol as a cutting fluid
will leave an aluminum surface resistant to corrosion. I am an optical
engineer and am always looking for manufacturing techniques that may be
useful for ultra-precise optical mounts and assemblies. There are times when
anodize is not an ideal surface finish for such things.
In any case it seems like if there is any truth to this rumor, it is not
common process. I may have to try the experiment myself.
