liquid wrench be ok as a cutting or tapping fluid ?

I don't see why not. I routinely use WD40 for working aluminum. Got tierd of the smell of kerosine

Liquid Wrench is nothing but kerosene in a high-priced can for suckers.

So, yes.

Well, now that I know that I think I'll take my can back to Sears tomorrow. :-) Thanks for the info! JCD

That's not what the MSDS says.

I'm not quite sure why you'd want to use a penetrant as a cutting fluid, but it's not kerosene.

Sure it does. If you know the nomenclature.

For aluminium, it is OK. Not for steel. So why not buy a real cutting fluid? Oh! Spit is good for aluminium, can't be cheaper.

Depends on what you expect a tapping/cutting fluid to do. Most of them simply carry away heat, either through flooding and convection, or through evaporation (energy absorption due to change of state). A few, like the old Rapid Tap that had 1,1,1-trichloroethane in it, actually created a thin oxide layer on the tool as soon as the tool got hot, and that oxide acted as the lubricant. The trick was to use only a drop so that the tool would get warm enough. Too many folks would flood it and the effect was lost. Of course, like anything that works well, it was outlawed, in this case because it affected the ozone layer. I don't know if the "new" Rapid Tap (must be 17 or 18 years old now) does the same thing, but it looks more like oil and doesn't work as well. I still have half a can of the old stuff that I use only on the toughest cuts. WD40 or kerosene or anything like that (I use Mouse Milk sometimes) will evaporate quickly and cool the tool. Makes less mess than having to flood it. The messiest stuff I ever used was a green goop that resembled yogurt that worked ok but left scum and lumps all over everything. Can't remember the name of it.

You talking about Anchor Lube?

The bottom-end formulation of Liquid Wrench is mostly naphtha.

That was it.

Dan

Would that be Molly-D?

Probably not what you mean by "naphtha", such as VM&P naphtha.

One MSDS gives, "PETROLEUM MID-DISTILLATE, ALIPHATIC PETROLEUM NAPHTHA".

Aka "kerosene".
