high speed die grinder bit, you can get them from any good engineering supply place, only triuble is they need to run at a high speed so you really
need an air powered die grinder

Should never use standard grinding wheels on alloy! The best tool for this is a
tungsten carbide burr.

Never argue with an idiot. They drag you down to their level, then beat you with experience.

And I found gear oil to be a great lubricant when porting aluminum.

WD40 is better.

Parafin is recommended
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Grinding Aluminium
Somewhere in Internet I read that you could use regular metal grinding discs/stones for aluminiumm if you apply them to a block of beeswax, and keep
doing it regularly.

***Disclaimer: Do the above at your own risk***
One thing I know for sure, is that you can cut longer with the Tungsten Carbide tips if you apply regular chalk on the grooves as this prevents
cuttings from piling up.
