Glycerine as cutting fluid.

I discovered a new use for glycerine, at least new to me, today by accident. Im doing some work at the moment that involves drilling lots of large holes in sheet metal. The stepped bit I was using was getting very hot and I looked around for water to dip the bit into. There was no water but there was a bucket of glycerine nearby. I dipped it in and hey presto the bit not only cooled but cut better and smoother. Forget expensive cutting fluid aerosols, just keep a pot of glycerine next to the pillar drill.

Yes. Pillar Drill. A drill on a pillar.Leave it to the Brits to take the English language literally. Cool

Darn handy that BD glycerine stuff. Will there ever be an end to all the great things it can do ?

Yes indeed pillar drill=drill press but on the other hand Brit does not =Irishman. I think it was Benjamin Franklin who said that we are forever divided by a common language.

No offence taken,
My glycerine is KOH based so it very liquid. I have filled a plastic bottle with a spray pump ( it use to contain my wifes window cleaner). It sits next to the pillar drill/ drill press and I can apply it easily while I work. NaOH based glycerine would probably not spray but it could be applied with a brush.

Parafin based stick lube is pretty common in machine shops so it stands to reason that glycerine would make an effective cutting compound.

I've used glycerin as a pipe threading fluid, works great.
