I know aluminum isn't a real durability test but these did the job quickly, make sure you use cutting oil and safety precautions etc

I guess I am going to have to grind off .2 mm to get the bit to cut 20 mm.

I purchased these for drilling shallow holes in pressure treated pine with a handheld drill. I do not recommend these for that purpose. The center point is not able to hold the bit in location and I was unable to keep the bit from walking.

Bit's package is good to store for a long time. Tried to make a hole in a laminated chipboard. Worked good. Circle edge was very good - no chips or unnecessary scratches.

I bored a hole in wood to hold a flashlight and soldering iron. Worked well. I think this one was a cheaper tear sh up bore but did the trick.
